Arabic expert

**Fluent Language Skills Required:** Korean. Native fluency in Korean, including full command of Hangul, is required for this position. All annotation and transcription work is performed in Korean.

**Why This Role Exists**

Document understanding breaks down fastest in the languages that parsing and vision-language models rarely see. This project builds training data for exactly those languages: Korean, alongside Japanese and five Indic scripts. Each task takes a real, publicly available PDF page and produces a complete structural map of that page, paired with a faithful transcription of every text region in the original script.

The dataset deliberately concentrates on the material models handle worst: handwriting, dense multi-column layouts, tables, diagrams, and mixed-script pages. Documents are drawn from newspapers, textbooks, examinations, and everyday formats such as flyers, forms, manuals, menus, brochures, notices and worksheets, so that the corpus reflects the real diversity of Korean documents rather than a narrow band of easily parsed ones.

Delivered work is human-authored throughout. Component identification, component typing, reading order and all transcription are performed by people, not generated by parsing models.

**What You'll Do**

- Source documents: find a publicly accessible Korean PDF in an assigned document type, containing at least one multimodal element (images, tables, diagrams, or handwriting), and record where you obtained it
    
- Annotate structure: identify and bound every meaningful region of the page - document title, section heading, paragraph, list, table, figure, diagram, caption, formula, question, answer field - and assign each a component type and a reading-order index
    
- Record relationships: link each region to the figure or table it belongs to through a parent component identifier
    
- Transcribe faithfully: reproduce all text exactly as it appears in Hangul, including any hanja and handwritten content, flagging any region where the source is not legible
    
- Capture page metadata: language, document type, source, page dimensions, and flags for tables, formulas and handwriting
    
- Review a colleague's work: every task is reviewed end to end by a second Korean expert, and experienced annotators take on that review
    

**Who You Are**

- You are a native Korean speaker with full command of Hangul, including hanja where it appears in older or formal documents
    
- You have worked in bilingual transcription, translation, editorial work, or AI training data, ideally with reviewer experience
    
- You are exact: character-level accuracy matters more here than speed, and a single wrong jamo is a defect
    
- You are systematic: you apply a taxonomy consistently across hundreds of pages rather than improvising per document
    
- You are comfortable with unfamiliar layouts: multi-column newspapers, exam papers, handwritten forms
    

**Nice-to-Have Specialties**

- AI training data: annotation, labeling, grading, or bilingual evaluation for training datasets
    
- Transcription and localization: MTPE, subtitling, bilingual QA, OCR correction or post-editing
    
- Document production: typesetting, copy-editing, proofreading, or digitization of Korean-language material
    
- Script and encoding: Unicode normalization, Korean input methods, Hangul jamo composition, and hanja handling
    

**What Success Looks Like**

- Every meaningful region on the page is captured, correctly bounded and correctly typed
    
- Reading order reflects how the page is actually read, including across columns
    
- Transcriptions match the source character for character, in Hangul rather than romanization
    
- Your tasks pass second-expert review the first time
    
- The documents you bring in add layout diversity rather than repeating templates already in the corpus
    

**Why Join Mercor**

- Build the training data that makes document AI work in scripts it currently handles badly
    
- Work from real published Korean documents rather than synthetic or templated pages
    
- Quality leads on this project: accuracy is the first measure, with handling time tracked alongside it

PDF Annotation & Transcription Experts – Japanese

**Fluent Language Skills Required:** Odia. Native fluency in Odia (Oriya), including full command of Odia script and orthography, is required for this position. All annotation and transcription work is performed in Odia.

**Why This Role Exists**

Document understanding breaks down fastest in the languages that parsing and vision-language models rarely see. This project builds training data for exactly those languages: Odia, alongside four other Indic scripts, Japanese and Korean. Each task takes a real, publicly available PDF page and produces a complete structural map of that page, paired with a faithful transcription of every text region in the original script.

The dataset deliberately concentrates on the material models handle worst: handwriting, dense multi-column layouts, tables, diagrams, and mixed-script pages. Documents are drawn from newspapers, textbooks, examinations, and everyday formats such as flyers, forms, manuals, menus, brochures, notices and worksheets, so that the corpus reflects the real diversity of Odia documents rather than a narrow band of easily parsed ones.

Delivered work is human-authored throughout. Component identification, component typing, reading order and all transcription are performed by people, not generated by parsing models.

**What You'll Do**

- Source documents: find a publicly accessible Odia PDF in an assigned document type, containing at least one multimodal element (images, tables, diagrams, or handwriting), and record where you obtained it

PDF Annotation & Transcription Experts – Odia

**Fluent Language Skills Required:** Malayalam. Native fluency in Malayalam, including full command of Malayalam script and orthography, is required for this position. All annotation and transcription work is performed in Malayalam.

**Why This Role Exists**

Document understanding breaks down fastest in the languages that parsing and vision-language models rarely see. This project builds training data for exactly those languages: Malayalam, alongside four other Indic scripts, Japanese and Korean. Each task takes a real, publicly available PDF page and produces a complete structural map of that page, paired with a faithful transcription of every text region in the original script.

The dataset deliberately concentrates on the material models handle worst: handwriting, dense multi-column layouts, tables, diagrams, and mixed-script pages. Documents are drawn from newspapers, textbooks, examinations, and everyday formats such as flyers, forms, manuals, menus, brochures, notices and worksheets, so that the corpus reflects the real diversity of Malayalam documents rather than a narrow band of easily parsed ones.

Delivered work is human-authored throughout. Component identification, component typing, reading order and all transcription are performed by people, not generated by parsing models.

**What You'll Do**

- Source documents: find a publicly accessible Malayalam PDF in an assigned document type, containing at least one multimodal element (images, tables, diagrams, or handwriting), and record where you obtained it

- Annotate structure: identify and bound every meaningful region of the page - document title, section heading, paragraph, list, table, figure, diagram, caption, formula, question, answer field - and assign each a component type and a reading-order index

- Record relationships: link each region to the figure or table it belongs to through a parent component identifier

- Transcribe faithfully: reproduce all text exactly as it appears in Malayalam script, including handwritten content, flagging any region where the source is not legible

- Capture page metadata: language, document type, source, page dimensions, and flags for tables, formulas and handwriting

- Review a colleague's work: every task is reviewed end to end by a second Malayalam expert, and experienced annotators take on that review

**Who You Are**

- You are a native Malayalam speaker with full command of the script, its diacritics and its conjunct forms

- You have worked with documents: annotation, transcription, translation, localization, subtitling, proofreading, journalism, or regional-language data review

Mexican Spanish expert

**About the role**

We build materials-science and engineering tasks that test how well an AI model does real expert work. You write a realistic task — a prompt, a data room, and a way to grade it — run it against the model, and tighten it until the model can no longer reason through it cleanly.

**What you'll do**

- Author domain-authentic tasks drawn from work you've actually done.
- Build the data room and grading criteria that make the task objectively scorable.
- Run the task against the model, analyse where it succeeds or fails, and iterate until it genuinely discriminates.
- Work with the project lead and other domain experts to settle what "good" looks like in your domain.

**Who we're looking for**

- Senior expertise in **materials science** — metals, ceramics, composites, characterization, additive manufacturing — or in **electrical engineering** (analog, RF, power) or **mechanical engineering** (design, CFD and fluids, heat transfer, pressure vessels, NDE, CAE).
- Comfortable navigating ambiguity — much of the work is still being defined, and shaping it is part of the role.
- Able to explain not just the right answer, but why a wrong answer is wrong.

**Support**

Daily onboarding sessions and multiple office hours every day.

Materials & Engineering Specialist

**About the role**

A frontier engineering-reasoning evaluation run in collaboration with a leading AI research lab. The work measures whether state-of-the-art models can reason from first principles in your engineering domain rather than retrieve facts from training data — and you get visibility into the model's internal reasoning on your own tasks.

**What you'll do**

Domain experts write simulations and specification sheets; the model attempts to design an artifact — controller gains, circuit parameters, geometry — that satisfies every spec.

You define the simulation, a set of specs with pass/fail thresholds, and the prompt. The model probes your simulation with a limited number of calls, then submits a final design. An agentic grader runs the simulation and scores spec satisfaction.

**Who we're looking for**

- Deep applied expertise in control systems, analog or RF circuits, power electronics, or mechanical design — PhD or equivalent industry track record.
- Comfortable writing simulations in Python and expressing acceptance criteria as quantitative, testable thresholds.
- Able to design a problem you can't shortcut yourself, but can still judge rigorously.
- Comfortable working in a browser-based studio and GitHub.

**Support**

Onboarding calls run daily, alongside internal tooling built to help you work faster. Prior model-evaluation experience is not required.

Engineering Simulation Specialist

**About the role**

This is an evaluation framework for frontier AI models in drug research and development. Domain experts write realistic research problems wrapped around messy evidence worlds. The model works offline in a sandbox with open-source scientific tooling, receiving incomplete, indirect and sometimes misleading data, and must reach a defensible conclusion. The answer is present in the evidence but never stated.

Your job is to build a research problem so realistic and well-constructed that the model has to genuinely reason to solve it — it can't pattern-match or look the answer up.

**What you'll deliver**

Three things per task: the prompt, the data room, and the grading document.

1. **Design the challenge** — identify the hidden basin and the forcing chain that makes one conclusion inevitable.
    
2. **Build the world** — assemble a data room from real, source-grounded data. Every decisive value traces to a real source.
    
3. **Write the grader** — a grading document that scores a submitted memo on substance, not style or method.
    
4. **Validate it** — run verification and calibration before submission.
    
5. **Revise it** — you own the rework if a reviewer requests changes.
    

You are the final authority on every scientific and difficulty question in your task.

**Who we're looking for**

- Working expertise in mechanistic enzymology, structure-guided peptide or antibody design, fragment-based discovery, or structure-based medicinal chemistry — PhD or equivalent industry track record.
    
- You can pose a problem whose answer you can defend rigorously, but which a strong solver cannot shortcut.
    
- Comfortable judging reasoning quality, not just final answers.
    

**Commitment**

Minimum 20 hours per week, up to 40.

**Tooling**

Work happens in a browser-based studio plus Claude Code. A Claude Max subscription is required and is fully reimbursed.

## About the role

Mercor is hiring **Corporate Designers** for Project Style — an aesthetics project in which experts review sets of AI-generated knowledge-work deliverables (decks, docs, spreadsheets, PDFs) and rework the strongest one until it's genuinely well-made, on both content and design.

Your work directly shapes how AI models produce polished, publish-ready knowledge work — the kind of output a consulting firm, investment bank, or in-house design team would send to a client without embarrassment.

## What you'll do

- Compare AI-generated versions of the same deliverable and score them across layout & spacing, typography, colour, domain realism, and polish
    
- Take the strongest candidate and rework it to reference quality
    
- Provide clear justifications tied to specific layout evidence (alignment, spacing, balance, grouping, density)
    
- Bring your design judgment to real corporate client materials
    

## You're a good fit if you

- Have a background as a designer, marketing/comms professional, or knowledge-work specialist — management consulting, investment banking, in-house corporate design, agency work, and marcom all fit
    
- Spot subtle layout inconsistencies most people miss: alignment gaps, unequal card heights, dead space, margin discipline
    
- Are opinionated about what "good" looks like in a business deliverable and can articulate it in writing
    
- Care about how work is presented, not just what it says
    

## Rate and commitment

- **$80/hour**, hourly
    
- Approximately **15 hours per week**
    
- Fully remote
    

## Screening

- Submit your resume and complete the Corporate Designer calibration assessment (~45 minutes)
    
- The assessment measures how well your ratings of real deliverables track against a calibrated answer key on the layout & spacing axis

## About the work

We are building high-fidelity simulated work environments used to evaluate and improve AI agents on real marketing work. Each environment reproduces a marketing org's actual tool surface — email, storage, CRM, project management, social media management, web analytics, AEO/SEO, ads, CMS, product analytics and support — populated with realistic documents, dashboards, personas and deliberately planted problems.

You will help design and pressure-test the Brand Marketing environments: the briefs, the artifacts, the judgment calls a strong practitioner would make, and the errors a weaker one would miss.

## What you will do

- Design task briefs drawn from work you have actually done in brand marketing, including what the task is really testing — the planted issue and the decision a strong practitioner should reach
- Specify the documents, dashboards, personas and tool states a realistic version of that task requires
- Write or review the reference answer and the criteria that separate a strong response from a plausible-but-wrong one
- Review AI agent attempts and judge them against your own standard

Tasks span the capabilities we measure: diagnosing what happened from messy or conflicting data, prioritizing and making tradeoffs, planning and executing, QA and reconciliation, triage and escalation, research and evaluation, reporting, and orchestrating multi-step work across several tools.

## Brand Marketing scope

Brand and share-of-voice analysis, messaging consistency across regions and channels, distinctive asset management, and channel and tactic decisions.

## Who we are looking for

- Hands-on practitioner experience in brand marketing — you have owned positioning, brand tracking and brand investment decisions
- Comfortable reading brand tracking studies, share-of-voice data and Google Analytics 4
- Prior experience building AI training environments, RL environments or simulated case studies is strongly preferred
- Rubric Academy or Rubric Bootcamp certification is strongly preferred
- Clear written reasoning — much of the value is in explaining why a decision is right

Each environment reproduces a marketing org's actual tool surface — email, storage, CRM, project management, social media management, web analytics, AEO/SEO, ads, CMS, product analytics and support — populated with realistic documents, dashboards, personas and deliberately planted problems.

You will help design and pressure-test the Content Marketing environments: the briefs, the artifacts, the judgment calls a strong practitioner would make, and the errors a weaker one would miss.

## What you will do

- Design task briefs drawn from work you have actually done in content marketing, including what the task is really testing — the planted issue and the decision a strong practitioner should reach
- Specify the documents, dashboards, personas and tool states a realistic version of that task requires
- Write or review the reference answer and the criteria that separate a strong response from a plausible-but-wrong one
- Review AI agent attempts and judge them against your own standard

Tasks span the capabilities we measure: diagnosing what happened from messy or conflicting data, prioritizing and making tradeoffs, planning and executing, QA and reconciliation, triage and escalation, research and evaluation, reporting, and orchestrating multi-step work across several tools.

## Content Marketing scope

Research and discovery, editorial prioritization, content production, and content QA and audit.

## Who we are looking for

- Hands-on practitioner experience in content marketing — you have owned an editorial program end to end, not only managed people who do it
- Comfortable working in a CMS such as Contentful, alongside Google Analytics 4 and a research tool such as Semrush
- Prior experience building AI training environments, RL environments or simulated case studies is strongly preferred
- Rubric Academy or Rubric Bootcamp certification is strongly preferred
- Clear written reasoning — much of the value is in explaining why a decision is right

## Screening

Applicants complete a short multiple-choice knowledge screener specific to this sub-domain before review.

Mercor's People team is building its compensation and equity foundation from scratch. We want to think it through with people who have done it before.

We're looking for Total Rewards practitioners with depth in **one or both** of the following. Either one on its own is enough.

**Compensation design & architecture**

- Built salary bands, leveling frameworks, and job architecture from the ground up
    
- Owned an annual compensation cycle: merit planning, promotion decisions, bonus programs, equity refresh
    
- Benchmarked against a peer set you then had to defend to a skeptical exec team
    
- Designed incentive structures that were simple, credible, and changed behavior
    

**Equity program management**

- Designed option and RSU programs: grant guidelines, pool planning, vesting structures, refresh philosophy
    
- Worked through 409A valuations, plan governance, and grant administration at a venture-backed company
    
- Built the modeling and communication that lets candidates and employees understand what their equity is worth
    

Those two are what we screen on. Nothing below is required. If you have the whole Total Rewards picture, say so.

**Also valuable**

- Compensation philosophy, benchmarking methodology, pay equity and pay transparency
    
- Compensation design for a global or contractor workforce at scale
    
- Benefits program design, HRIS and compensation tooling
    
- Executive compensation, plan governance, or equity through IPO readiness
    

**Context**

Mercor is a Series C company at a $10B valuation, scaling from roughly 500 employees, with a large global contractor network alongside a growing full-time workforce. Nothing is settled yet: what the compensation philosophy should be, how levels map across very different functions, how equity gets granted and explained.

**How this works**

Applying starts with a short screen. If your background fits, we'll invite you to a paid conversation about a live question we're facing. You're paid for it whether or not anything follows.

Rate is $50–$200/hr depending on depth of experience. Engagements run a few hours at a time, scoped to one question.

We review every submission.

- **AI fluency:** Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
    
- **Availability:** Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
    
- **Location:** Living in the Bay Area, California, and able to work on-site with the client's team multiple days each week, when required. Candidates not currently based in the Bay Area must be willing to relocate there at their own cost. Relocation assistance is not provided.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

We are hiring a senior **accounting and audit domain expert** to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real accounting and audit work.

Your accounting expertise is the substance of this role. You will review the quality of accounting knowledge work tasks, write the instruction specs and golden solutions that define what "correct" looks like, and build the benchmarks that show whether the model is genuinely improving. We are looking for a practicing specialist rather than a generalist.

This is a full-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.

**Location:** This is a **hybrid** role based in the **Bay Area, California**. You must live in the Bay Area and work on-site with the client's team multiple days each week, when required. This is not a remote role. If you do not currently live in the Bay Area, you must be willing to relocate there at your own cost before the engagement starts. Relocation assistance is not provided.

## 2\. Key Responsibilities

- **Data QA and reviews:** Vet the quality of accounting and audit knowledge work tasks and model outputs, spotting missing behaviors, thin reasoning, misapplied standards, unsupported accounting treatments, and answers that read well but would not survive review by a reviewing partner.
    
- **Instruction specs and golden datasets:** Write high-quality instruction specs, produce golden solutions to accounting and audit problems, and define new tasks that reflect how the work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging accounting and audit tasks and evaluation sets, and help build domain-specific skills and tools together with the research team.
    
- **Calibration:** Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit accounting judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Credentials:** An active professional credential, for example CPA, CA, CIA, CFE, or CMA, alongside a bachelor's or master's degree in accounting or a closely related field.
    
- **Experience:** 4+ years of substantive accounting or audit experience at a recognized institution, for example a public accounting firm, a corporate controllership or finance function, an internal audit department, or a regulator. Bookkeeping-only roles do not count.
    
- **Domain depth:** Genuine specialization in at least one area, for example external audit and assurance, technical accounting and financial reporting under US GAAP or IFRS, internal audit and SOX controls, tax, forensic accounting and fraud examination, or revenue recognition.
    
- **Seniority:** Clear progression to a senior level, for example Audit Manager, Senior Manager, Accounting Manager, Controller, Director of Accounting, or Partner, with real ownership of engagements or reporting cycles.
    
- **AI fluency:** Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
    
- **Availability:** Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
    
- **Location:** Living in the Bay Area, California, and able to work on-site with the client's team multiple days each week, when required. Candidates not currently based in the Bay Area must be willing to relocate there at their own cost. Relocation assistance is not provided.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

Engineering & Software Domain Expert

**Mercor is partnering with a venture-backed AI lab building frontier AI platforms and physics-based foundation models for chemistry, materials science, and drug discovery.** They're extending their platform into new areas of pharmaceutical development and are looking for hands-on preclinical R&D experts across drug modalities to help guide what they build.

Are you a preclinical R&D scientist who has taken drug programs from the bench toward the clinic — and curious how AI is reshaping drug discovery? This is a hands-on role that blends your wet-lab and translational experience with a growing understanding of how scientific data trains the next generation of AI models.

**In this role, you'll:**

- Review technical materials and real-world R&D data in your area of expertise

- Label, classify, and annotate scientific data and model outputs to improve model performance

- Provide expert perspective on key scientific and development decisions (target/modality selection, optimization, trade-offs, risk)

- Help define structure and quality standards for the client's dataset pipeline

- Participate in expert discussions, interviews, and research engagements

**You're a strong fit if you:**

- Have hands-on, non-administrative preclinical R&D experience at a company that develops its own drug assets in-house and has taken programs to the clinic — Must Have

- Work in a core R&D function: discovery biology, medicinal chemistry, protein/antibody engineering, computational, in vivo/translational, pharmacology/PK-PD, toxicology, or CMC/formulation — Must Have

- Have hands-on experience with one or more drug modalities (small molecules, monoclonal antibodies, peptides, ADCs, bispecifics, mRNA, siRNA, ASOs, PROTACs, molecular glues, cell therapies, gene therapies, radioligand therapies, etc.) — Must Have

- Have 5+ years of relevant industry R&D experience (flexible based on depth)

- Have taken a program through lead optimization or IND-enabling/preclinical development (nice to have)

- Have experience at mid-sized, emerging, or resource-constrained biotech — ideally currently outside the top-20 pharmaceutical companies (nice to have)

This is a hands-on preclinical R&D role — likely **not the right fit** if your work is mainly CRO/CDMO services, academic-only, QC/analytical-only, clinical-development-only, diagnostics, or regulatory/medical-writing.

Your work will directly feed into the models reshaping how medicines are discovered, helping intelligent systems reason about real-world pharmaceutical R&D.

**Here are more details about the role:**

- You will interface directly with the client team.

- This is an ongoing, part-time engagement of roughly 10 hours per week.

- Seniority welcome from individual contributor through Director.

Preclinical R&D Expert – In-house Drug Development

**About the work**

We're building a high-quality dataset of human preference judgments on AI-generated frontend code. Each task hands you a reference web page — crawled from the real internet, delivered as a full zipped site tree plus screenshots of its default view and, on some pages, additional states reached by hovering, clicking, or scrolling. Alongside it come two model attempts, A and B, each a zipped self-contained site tree. The models only ever saw the screenshots; they never had the source.

You download all three, run them locally, view each at a 1920×1080 viewport, interact with them to reach every required state, then open the source of both attempts and grade them against each other — on visual fidelity per state, and on how the code is actually constructed. Structure and responsiveness are explicitly part of the rubric, not just the render.

This is evaluation work, not authoring. The defining skill is not that you can build a page — it's that you can open someone else's page and tell how it was built and where it cheats.

**Please read before applying**

- Each unit takes roughly 2–3 hours and is timed. This is not microtask work; if you can only offer scattered 15-minute windows, you will not be able to finish a unit.
    
- You need a real local development environment. A tablet, a Chromebook, or a locked-down work machine that cannot run a local static server will not work for this project.
    
- You need at least one completed Mercor engagement, delivered in full. We are not onboarding net-new experts to this project.
    

**What you'll do**

- Render a reference page and two candidate replications at 1920×1080 and judge which is the closer reproduction, state by state.
    
- Diff visual fidelity in detail: box model and spacing, typography (family, size, weight, line-height, letter-spacing), color and border treatment, image and asset handling, z-order and overflow.
    
- Read the source of both attempts and grade construction quality — distinguishing a replication that is genuinely correct from one that merely looks correct at one viewport. Hardcoded pixel offsets, absolute positioning standing in for real layout, inline style soup, a single undifferentiated div tree, or a screenshot pasted in as an `<img>` instead of a rebuilt section.
    
- Test responsiveness: a nav bar that looks right at 1920px but collapses at 1400px is a defect, and you should be able to say precisely why.
    
- Write a specific, evidence-cited justification for every preference. We need "B nests the article body in a single absolutely-positioned div, so the text overlaps the footer below 1600px, while A uses normal document flow" — not "A looks closer."
    
- Use the "this task is broken" escape hatch with judgment: distinguish a task that genuinely cannot be completed from the screenshots provided from one that is merely hard. Over-flagging and under-flagging are both failure modes.
    

**You're a fit if you have**

- 3–8 years of professional web development experience, shipping web interfaces for a living, primarily in frontend or full-stack work.
    
- Fluency across web eras. The reference pages are real crawled sites — one is a small charter-fishing business built in the table-and-image-map tradition, another a corporate press-release page with stacked navigation rows and social share widgets. If your entire career happened inside a modern component framework and you have never authored raw CSS or seen a `<table>` used for layout, you will misjudge many of these pages.
    
- Command of hand-written HTML and CSS: semantic markup, flexbox, grid, media queries, and legacy float- and table-based layouts you can read and reason about. You should be able to look at a rendered layout and predict what's holding it together before opening DevTools.
    
- Browser DevTools as muscle memory — setting an exact viewport, walking the element tree, checking computed styles, watching what a hover handler mutates.
    
- Command-line comfort: unzipping an archive, standing up a static local server because the relative asset paths demand it, and untangling a broken image reference rather than giving up and grading from the screenshot.
    
- Enough JavaScript to read a page's scripts and understand what they do to the DOM, even if you don't write JS daily.
    
- Professional written English. Every task ends in a free-text justification, and a rating without a specific rationale is worth very little.
    

**Equipment**

- A desktop or laptop that displays a 1920×1080 viewport.
    
- Administrator rights on your own machine, so you can install and run a local server.
    

**Nice to have**

- Prior RLHF, preference-labeling, model-evaluation, or structured code-review work — the strongest single signal. Rubric-driven comparison at volume needs almost no ramp here.
    
- Pixel-perfect design-to-code experience: agency work, design systems, template production. Anyone who has had a designer reject a build over four pixels has exactly the fidelity eye this needs.
    
- Accessibility expertise (ARIA, semantic landmarks, heading hierarchy) — you'll notice immediately when an attempt renders a heading as a styled `<span>`.
    
- Familiarity with how LLMs fail at code generation.
    
- Web scraping, archiving, or DOM-parsing background — comfort with messy crawled site trees.
    
- More than one completed Mercor project, and availability in contiguous multi-hour blocks.
    

**Note:** this seat is for practicing web developers. Backend-only, ML/data-science-only, mobile-native-only, and DevOps-only engineers do not have the UI instincts this requires, however strong they are otherwise. Designers who do not code cannot grade the source axes at all. Framework-only engineers who have never authored CSS outside a component library will struggle with the legacy reference pages.
