Human Resources Specialist

## Role Overview

Mercor is partnering with a leading AI lab to build a network of government, public policy, and regulatory affairs experts who help train and evaluate frontier AI systems on real-world public-sector work. As a Government & Public Policy Expert, you will apply your professional judgment to author, review, and stress-test tasks spanning the full policy and administrative lifecycle — policy analysis and memo drafting, regulatory drafting and compliance review, procurement and contracting, program and grants management, budget and appropriations, and legislative affairs. Your expertise directly shapes how advanced AI models reason about the decisions that agencies, legislatures, and public institutions face every day.

## Key Responsibilities

- Design realistic public-sector scenarios and tasks drawn from your hands-on experience: policy options analysis, decision memos, briefing papers, and issue backgrounders for senior officials.
    
- Build and review regulatory work products — proposed and final rule text, preambles and regulatory impact discussion, public-comment analysis, guidance documents, and compliance determinations against controlling statute and regulation.
    
- Create procurement and contracting exercises grounded in real practice: requirements and statements of work, RFP/solicitation development, FAR and agency-supplement analysis, evaluation criteria, source-selection rationale, and contract administration issues.
    
- Develop program and grants management tasks covering notices of funding opportunity, application review and scoring, subrecipient monitoring, performance measurement, and reporting obligations.
    
- Author budget and appropriations tasks — budget justifications, spend plans, reprogramming and apportionment questions, cost estimates, and fiscal-law issues such as purpose, time, and amount.
    
- Draft legislative affairs materials, including bill analysis, fiscal notes, amendment tracking, testimony preparation, and constituent or stakeholder correspondence.
    
- Review and grade AI-generated outputs for accuracy, completeness, procedural soundness, and fidelity to the governing authority; identify subtle errors, edge cases, and failure modes in model reasoning.
    
- Provide clear, structured written rationale explaining why a given answer is correct, incomplete, or wrong, and collaborate with the team to refine evaluation rubrics and raise the quality bar for this domain.
    

## Ideal Qualifications

- 3+ years of professional experience in government, public policy, or regulatory affairs.
    
- Federal, state, local, tribal, and agency-adjacent experience is all welcome — including civil service and political appointments, legislative staff, regulatory agencies, public authorities and special districts, government contractors and consultancies, think tanks, trade associations, advocacy organizations, and in-house government affairs or regulatory teams.
    
- Depth in one or more sub-domains: policy analysis and memo writing, rulemaking and regulatory compliance, procurement and contracting (FAR, RFP/solicitation, source selection), program and grants management, budget and appropriations, or legislative affairs.
    
- Working command of the administrative process — how authority flows from statute to regulation to guidance to implementation — and of the tradeoffs, constraints, and stakeholders that shape real public decisions.
    
- Excellent written communication, with the ability to explain nuanced reasoning clearly and concisely for a decision-maker audience.
    
- Sharp attention to detail, citation discipline, and comfort evaluating the quality of others' work.
    
- A relevant credential or degree (MPP, MPA, JD, CFCM/CPCM, PMP, or comparable) is preferred but not required — demonstrated hands-on experience matters more.

Human Resources Expert

**About the Opportunity**

A leading AI research organization is starting a focused Finance Sprint within Project Mercury in the next 24 hours. We are seeking experienced finance professionals to evaluate whether individual workflows and tasks accurately reflect real professional practice in their specialist domain.

Offers are first-come, first-served. This will be a high-engagement project over the next week, so please apply only if you can stay actively involved throughout the sprint. Work may involve completing multi-hour tasks in one sitting, typically around 2–4 hours, and requires keeping Slack notifications on and responding to project updates, questions, and feedback within the day.

This is a workflow-realism evaluation engagement. You will use your professional judgment to assess whether each task, its provided context, expected workflow, and constraints would make sense in real practice. The exact task content is confidential and may vary during the sprint.

**What You'll Do**

- Review individual finance tasks and workflows for professional realism, clarity, scope, and internal consistency
- Assess whether the task inputs, context, and expected workflow reflect how the work is actually performed in your domain
- Identify missing assumptions, ambiguous instructions, unsupported requirements, impractical constraints, and material edge cases
- Flag where a task is too broad, too generic, or otherwise unlikely to produce a meaningful signal of real finance capability
- Provide concise, structured written feedback and targeted recommendations to improve task realism
- Where needed, cross-check task logic with trusted domain peers to maintain a high bar across the sprint

**Who We're Looking For**

- 5–9 years of relevant experience for the practitioner track, or 9–15 years for the senior reviewer track
    
- Professional experience in fundamental equity research, asset management, hedge funds, or a closely related investing role

Finance Expert — Public Equities Analyst / PM

**About the Opportunity**

A leading AI research organization is starting a focused Finance Sprint within Project Mercury in the next 24 hours. We are seeking experienced finance professionals to evaluate whether individual workflows and tasks accurately reflect real professional practice in their specialist domain.

Offers are first-come, first-served. This will be a high-engagement project over the next week, so please apply only if you can stay actively involved throughout the sprint. Work may involve completing multi-hour tasks in one sitting, typically around 2–4 hours, and requires keeping Slack notifications on and responding to project updates, questions, and feedback within the day.

This is a workflow-realism evaluation engagement. You will use your professional judgment to assess whether each task, its provided context, expected workflow, and constraints would make sense in real practice. The exact task content is confidential and may vary during the sprint.

**What You'll Do**

- Review individual finance tasks and workflows for professional realism, clarity, scope, and internal consistency
- Assess whether the task inputs, context, and expected workflow reflect how the work is actually performed in your domain
- Identify missing assumptions, ambiguous instructions, unsupported requirements, impractical constraints, and material edge cases
- Flag where a task is too broad, too generic, or otherwise unlikely to produce a meaningful signal of real finance capability
- Provide concise, structured written feedback and targeted recommendations to improve task realism
- Where needed, cross-check task logic with trusted domain peers to maintain a high bar across the sprint

**Who We're Looking For**

- 5–12 years of relevant experience for the practitioner track, or 10–18 years for the senior reviewer track
- Experience in public-sector finance, municipal credit, public pensions, fiscal policy, applied economics, or empirical finance
- Strong quantitative reasoning and fluency with financial or econometric analysis
- Ability to assess evidence quality, methodological choices, causal claims, and policy interpretations
- Excellent written communication and the ability to explain not only whether something is correct, but why
- High attention to detail, sound professional judgment, and comfort evaluating work against explicit standards

Expert Project Manager

**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

Join a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking talented Molecular Biology subject-matter experts (SMEs) with hands-on experience designing DNA and RNA sequences — primers, plasmids, guide RNAs, mRNA constructs, and repair templates — to bring deep domain expertise and elevate the quality of our AI training data. This is a part-time to full-time commitment of up to 40 hours per week.

This is a W-2 employment position with Cincinnatus LLC (or appropriate international entity), with the opportunity to be placed at a leading AI Lab as part of their extended workforce.

# 2\. Key Responsibilities

- Guide research and engineering teams to close knowledge gaps and improve AI model performance in molecular biology, nucleic-acid sequence design, and construct engineering.

- Design challenging, domain-relevant tasks and write accurate, well-documented solutions — spanning primers (PCR/qPCR/cloning), plasmids/expression vectors, gRNA/sgRNA for CRISPR editing, mRNA/RNA constructs, and HDR/repair templates — that serve as ground truth.

- Evaluate molecular-biology tasks and AI model outputs against expert-quality solutions and provide clear, written technical feedback on correctness, rigor, and biological reasoning.

- Develop guidelines and detailed rubrics/evaluation frameworks to assess sequence-design quality — guide/target selection, homology-arm length, primer melting temperature and specificity, codon optimization, and regulatory elements.

- Collaborate with other subject matter experts to ensure consistency and accuracy in training data.

# 3\. Core Qualifications

- Advanced degree (PhD strongly preferred) in molecular biology, genetics, biochemistry, synthetic biology, bioengineering, or a related life-science field.

- Hands-on experience designing nucleic-acid constructs prior to experiments — across several of primers, plasmids/vectors, gRNA/sgRNA, mRNA, and HDR/repair templates — together with cloning strategy (Gibson, Golden Gate, Gateway, restriction) and codon optimization.

- A strong peer-reviewed publication record, weighted toward first-author work in notable venues (e.g., Nature and the Nature family, Cell, eLife, Nucleic Acids Research, PNAS, EMBO Journal). Please include publication links with your application.

- Demonstrable career progression.

- Ability to engage reliably for at least 20 hours/week during weekdays.

- Past experience in AI training, model evaluation, and data annotation is preferred.

- Strong written communication skills and the ability to justify design choices clearly and precisely.

## Non-Investment Finance Expert — AI Training & Evaluation

We're building frontier AI for complex, real-world finance work, and we need senior finance practitioners to produce and evaluate expert-grade work products that set the bar for what "correct, professional output" looks like. You'll work through realistic, document-heavy scenarios — messy source files, distractors, ambiguous guidance — and either produce the deliverable yourself or judge AI-generated attempts against a professional standard. This is hands-on finance craft, not survey-taking.

### What you'll do

- Build and review deliverables such as: PnL and mark-to-market reconciliations (trader vs. accounting, month-end marks, commissions, adjustments); vendor / AP payment reconciliations under cash constraints with controls (PO, P-card, aging); integrated 3-statement and pro-forma models including purchase-accounting impacts (ASC 805 deferred-revenue haircut, PPA amortization, synergy phasing); covenant and credit analysis; and partnership / professional-services allocations (profit-pool waterfalls, capital accounts).
    
- Reason from primary sources — term sheets, purchase/partnership agreements, trial balances, memos, emails — and separate what's material from deliberate distractors.
    
- Write clear, CFO/partner-ready narratives that explain assumptions, variances, and recommendations.
    

### Who we're looking for

- 5+ years in a hands-on non-investment finance role: product control / financial control, corporate FP&A, technical accounting, treasury / financial operations / AP–P2P, commercial-banking credit, or professional-services / partnership finance.
    
- CPA / CA / ACA / ACCA / CIMA (or equivalent) strongly preferred.
    
- Strong US GAAP / IFRS (bonus: ASC 805 & 606) and advanced Excel modeling (linked 3-statement models, reconciliations, pro formas).
    
- Comfort exercising professional judgment on incomplete or ambiguous information.
    
- Note: a CFA / investing / portfolio-management background is not required — this is operational and technical finance, not markets.

\- Producing high-quality video and film for leading technology companies, global brands, startups, or cultural institutions

\- End-to-end production: scoping, budgeting, scheduling, client management, and directing creative teams through delivery (producer track)

\- Editing, motion design, and finishing in tools such as Premiere Pro, After Effects, DaVinci Resolve, or Cinema 4D (editor track)

\- Commercial, branded content, or campaign film production

\- Collaborating with multidisciplinary teams to deliver polished, production-ready film and video

**Preferred candidates have experience at one or more of the following studios:**

\- BUCK

\- Tendril

\- Future Deluxe

**About this study**

Mercor is building a new, more accurate version of O\*NET — 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 software developers is described.

**About the role (SOC 15-1252.00 — Software Developers)**

Software developers research, design, and build computer software, network software, or specialized utility programs. They analyze user needs, determine the feasibility of designs within time and cost constraints, and develop software solutions by applying principles of computer science, engineering, and mathematical analysis. Their work spans the full development lifecycle: defining specifications and performance requirements, architecting systems, directing testing and validation procedures, and modifying existing software to correct errors, adapt to new hardware, or improve performance. They may coordinate with hardware engineers to integrate hardware and software systems, and they often own decisions about system design rather than executing designs handed to them.

**This occupation excludes**

- **Web developers (15-1254.00)**, whose work centers on developing and implementing websites, web applications, and interactive web interfaces. A worker whose primary responsibility is building or maintaining websites, optimizing website performance, or integrating websites with other applications is a web developer, even if they write substantial application code. The distinguishing test is the artifact: web developers produce web properties; software developers produce software systems and applications more broadly, of which the web may be one deployment surface among many.
    
- **Computer programmers (15-1251.00)**, who create, modify, and test code working from specifications drawn up by software developers or others. The distinguishing test is authorship of the design: programmers implement designs they are given, while software developers analyze requirements, produce the design, and direct development. A worker who primarily writes and debugs code to someone else's specification is a programmer, not a developer.
    

**What you'll do**

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

**Who we're looking for (eligible applicants have)**

- **4+ years of experience working specifically as a software developer.**
    
- **Current work, or work within the last 12 months, in the role.**
    
- **Direct knowledge of design, coding, and deployment tasks.**
    
- **U.S.-based.**
    

**Not eligible (common confounders)**

- Software QA analysts and testers whose role is testing rather than development (SOC 15-1253.00).
    
- IT support, help desk, or system administrators who do not develop software.
    
- Computer programmers (SOC 15-1251.00).
    
- Web developers (SOC 15-1254.00).
    
- Computer systems analysts (SOC 15-1211.00).
    
- Computer systems engineers (SOC 15-1299.08).
    
- Computer and information systems managers (SOC 11-3021.00).

We're looking for professionals with deep, hands-on experience in the administrative and operational work that keeps healthcare organizations running — the "back office" of a medical practice, hospital, or health plan. This spans the full administrative lifecycle: getting patients registered and covered, securing authorizations, moving claims through to payment, managing provider and payer relationships, and keeping records and compliance in order. You'll help us understand the precise steps these workflows take in the real tools you use every day.

AI Rater Guidelines Writer (Linguist / Instructional Designer)

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
