AI Rater Guidelines Writer (Linguist / Instructional Designer)

**About this study**

Mercor is building a new, more accurate version of ONET — the U.S. government's framework for describing occupations and the tasks they involve. We are gathering input directly from experienced practitioners to improve how the work of accountants is described.

**What you'll do**

- Complete a one-time online survey/interview about your day-to-day work as an accountant. It takes **up to 30 minutes**.
    
- There may be an optional follow-up survey, task, or short interview afterward, which would be paid separately.
    

**Pay**

- Pay is set in proportion to the expected hourly wage for accountants (~$39/hour). The initial task is \*\*~30 minutes\*\*, so it pays roughly half an hour at that rate, with the potential for additional paid tasks later.
    

**Who we're looking for**

- **2+ years of experience working specifically as an accountant** (SOC 13-2011 — Accountants and Auditors).
    
- **U.S.-based.**
    
- **Currently employed as an accountant, or employed in the role recently** — we are not looking for people who left the profession many years ago.
    
- You must have actually held an accountant role. Accounting students or people with only general finance exposure are not a fit unless they have genuinely worked as an accountant.

Accountant - Research Survey (ONET Occupation Study)

We are recruiting a select cohort of accomplished physics researchers to contribute to the next generation of AI systems for scientific reasoning. Our partner labs are building models that need to reason about theoretical physics, condensed matter, quantum information, particle physics and high-energy theory, astrophysics and cosmology, atomic/molecular/optical (AMO) physics, plasma physics, biophysics, statistical and computational physics, and mathematical physics at the level of a working researcher — not a textbook. To get there, they need contributors whose own research sits at the frontier.

This position will be placed at a leading AI lab as part of their extended workforce.

## What you'll do

- Review and evaluate research papers in physics for correctness, novelty, and significance
- Author and review challenging physics problems used to train and evaluate frontier AI models
- Evaluate model outputs on tasks ranging from analytical derivation and mechanism prediction to numerical modeling, experimental design, and literature reasoning
- Surface areas where current models fail — especially the kinds of mistakes a working PhD physicist would catch immediately
- Collaborate with a small program team and other senior contributors

## Qualifications

We're looking for researchers who meet several of the following:

- First-author or co-first-author publications in journals such as Physical Review Letters, Physical Review X, Reviews of Modern Physics, Nature Physics, Nature, Science, PNAS, Nature Communications, the Physical Review A/B/C/D/E family, Physics Letters B, the Journal of High Energy Physics, the Astrophysical Journal, Monthly Notices of the Royal Astronomical Society, Quantum, or Communications Physics
- A doctorate or postdoctoral training from a top-20 global institution in physics or a related STEM field
- A competitive fellowship, such as an NSF Graduate Research Fellowship, a Hertz Fellowship, a DOE Computational Science Graduate Fellowship, a DOE Early Career award, a Sloan Research Fellowship, a Packard Fellowship, a Simons Investigatorship or Junior Fellowship, a Hubble, Einstein, Sagan, or Kavli (KITP) Fellowship, a Marie Curie/MSCA award, a Fulbright, Rhodes, Marshall, Gates Cambridge, or Schmidt Science Fellowship, an NSF CAREER award, or an APS Fellowship
- Issued patents, a spin-out company, or grants held as a named Principal Investigator or Co-Investigator
- An International Physics Olympiad (IPhO) Gold, Silver, or Bronze medal
- Current or recent experience in an active research role, as a PhD candidate, postdoctoral researcher, instructor, faculty member, principal scientist, or industry researcher; current title matters — we prioritize active faculty, postdoctoral researchers, or PhD candidates over general staff research-scientist titles

Outstanding senior PhD students and recent graduates with strong publication records are strongly encouraged to apply; the depth of your research output matters more than years of experience.

## Engagement

- Part-time: up to 20 hours per week
- Compensation reflects research seniority and credentials

Physics Research Collaborator (Part-time)

We are recruiting a select cohort of accomplished chemistry researchers to contribute to the next generation of AI systems for scientific reasoning. Our partner labs are building models that need to reason about organic synthesis, mechanism, catalysis, structural and physical chemistry, chemical biology, computational and theoretical chemistry, and materials at the level of a working researcher — not a textbook. To get there, they need contributors whose own research sits at the frontier.

This position will be placed at a leading AI lab as part of their extended workforce.

## What you'll do

- Review and evaluate research papers in chemistry for correctness, novelty, and significance
- Author and review challenging chemistry problems used to train and evaluate frontier AI models
- Evaluate model outputs on tasks ranging from retrosynthesis and mechanism prediction to spectral interpretation, computational chemistry, and literature reasoning
- Surface areas where current models fail — especially the kinds of mistakes a working PhD chemist would catch immediately
- Collaborate with a small program team and other senior contributors

## Qualifications

We're looking for researchers who meet several of the following:

- First-author or co-first-author publications in journals such as JACS, Nature Chemistry, Science, Nature, Angewandte Chemie, Nature Catalysis, ACS Catalysis, Chem (Cell Press), Chemical Reviews, Chem Soc Rev, the Journal of Organic Chemistry, Organic Letters, Inorganic Chemistry, or Nature Communications
- A doctorate or postdoctoral training from a top-20 global institution in chemistry or a related STEM field
- A competitive fellowship, such as an NSF Graduate Research Fellowship, a Hertz Fellowship, a Sloan Research Fellowship, a Camille and Henry Dreyfus award, a Searle Scholar or Pew Scholar award, a Beckman Young Investigator award, an NIH F32/NRSA, a Damon Runyon, Helen Hay Whitney, Marie Curie, Fulbright, Rhodes, Marshall, Gates Cambridge, or Schmidt Science Fellowship, an NSF CAREER award, or a DOE Early Career award
- Issued patents, a spin-out company, or grants held as a named Principal Investigator or Co-Investigator
- An International Chemistry Olympiad (IChO) Gold, Silver, or Bronze medal
- Current or recent experience in an active research role, as a PhD candidate, postdoctoral researcher, instructor, faculty member, principal scientist, or industry researcher

Outstanding senior PhD students and recent graduates with strong publication records are strongly encouraged to apply; the depth of your research output matters more than years of experience.

## Engagement

UK-Based Accounting Specialists

**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

A leading AI lab is growing a team of chip design and verification engineers to help shape how its models understand real hardware engineering work. If you've spent your career chasing down a bug across multiple blocks, architected a piece of RTL from scratch, or fought a design through timing and coverage closure, we want to hear from you — the goal is to bring that same kind of real-world judgment into the problems these models are trained and tested on.

We're building out this team across experience levels, from PhD students and new grads just starting out to senior engineers who've taken silicon all the way to tapeout. There's no single "right" background here — what matters is that you've actually done the work, not just studied it.

This is a part-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. This role is fully remote within the United States, at roughly 20–40 hours per week depending on your availability.

## 2\. Key Responsibilities

- Design and write up realistic chip engineering problems drawn from your own experience — the kind of design, debugging, or verification work you've actually done, not textbook exercises.
    
- Build out full solutions to go with them: reference RTL, testbenches, and supporting materials, using SystemVerilog/Verilog and the tools you already know.
    
- Run your problems against an AI model, see where it holds up and where it doesn't, and help explain why.
    
- Work alongside other engineers on the team to keep everyone's work at a consistent bar of rigor and difficulty.
    

## 3\. Core Qualifications

- Hands-on ASIC/SoC design and/or functional verification experience, ideally with exposure to production silicon that's been taped out.
    
- Strong fluency in SystemVerilog/Verilog.
    
- Comfortable working in industry toolchains (e.g., Synopsys VCS, Cadence Xcelium, Siemens Questa, VC Formal, Verdi) and/or their open-source counterparts (Icarus Verilog, Verilator, CocoTB, Yosys, OpenROAD).
    
- Solid grasp of subsystem/SoC-level concerns: interface protocols, handshaking and backpressure, multiple clock domains, and multi-module dataflow.
    
- Real depth in at least one of the following: RTL design & microarchitecture; IP integration, bring-up & system configuration (NoC, PCIe, DDR, ARM/AXI); functional verification (UVM, SVA, CocoTB; testbench architecture); formal verification & coverage closure; PPA, timing, and synthesis optimization; analog/mixed-signal design verification; or specification authoring, comprehension & Q&A.
    
- Able to commit 20–40 hours per week, with confirmed availability and no scheduling conflicts.
    
- Past experience in AI training, model evaluation, or data annotation is a plus.
    
- Strong written communication and comfortable working independently.

Machine Learning & NLP Expert

**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

A leading AI lab is teaching its AI to do real enterprise sales work — the kind of multi-step, judgment-heavy workflows that only someone who has actually carried a quota knows how to get right. To do that well, they need seasoned sellers to act as the ground truth: people who can show the model what excellent looks like, catch where it goes wrong, and set the bar its work is measured against.

That is where you come in. As a Sales Domain Expert, you will bring years of real selling experience to auditing sales workflows, building the "golden" reference examples the model learns from, and shaping the rubrics used to evaluate it. This is a role for accomplished enterprise sellers — not general data annotators.

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. This role is fully remote within the United States.

## 2\. What You'll Do

- **Set the standard for "good":** Review multi-step enterprise sales workflows and judge whether the AI handled them the way a strong seller would, flagging what is off and why.
    
- **Build golden trajectories:** Work real sales tasks end-to-end — prospecting, pipeline management, CRM hygiene, reporting, and customer-facing documents — to create the expert reference examples the model is trained on.
    
- **Shape the evaluation:** Pressure-test and refine the rubrics used to score AI outputs so they capture what actually separates great selling from average.
    
- **Work in realistic sandboxes:** Operate inside test environments that mirror a real sales tech stack, completing and simulating workflows across CRM, communication, and billing tools.
    
- **Produce senior-level artifacts:** Create polished, customer-facing materials — pitches, slide decks, and summaries — at the quality a senior sales leader would put their name on.
    

## 3\. Who We're Looking For

- Around 10 years of hands-on experience selling in enterprise environments, with a real feel for the full sales cycle.
    
- A consistent track record of meeting or exceeding your sales quota, which you can speak to in specifics.
    
- Sellers at every level are welcome — quota-carrying individual contributors, managers who lead selling teams, and VPs running regional or global sales organizations.
    
- Day-to-day fluency with the standard enterprise stack (Salesforce, Jira, Confluence, Google Workspace, and Microsoft Office), and the comfort to pick up tools like Slack, HubSpot, Notion, Aircall, Stripe, Intercom, Zoho, and Microsoft Teams.
    
- Genuine depth in CRM administration, sales process management, pipeline tracking, and data-driven reporting.
    
- Strong writing and a good eye for polish — you can turn a complex situation into a clear, professional, customer-facing artifact.
    

## Nice to Have

- Experience working within or alongside a two-sided, AI-powered B2B SaaS creator marketplace — for example, running outcome-based campaigns against contracted performance targets (tracking views, engagement, installs, and sign-ups in real time) and troubleshooting across a connected stack such as Zoho CRM, Jira, Confluence, Freshdesk, Microsoft Teams, and Google Workspace. If this sounds like you, tell us — we are especially keen to talk.
