**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
    
- Strong financial-statement analysis, forecasting, valuation, and investment-judgment skills
    
- Experience covering TMT or semiconductors, or conducting event-driven and SEC-filings-intensive research, is a strong plus
    
- 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
    
- Experience reviewing analysts, approving work, designing controls, or setting quality standards is especially valuable for the senior track
    

**Why This Work Matters**

## 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.

## Consulting Expert — AI Training & Evaluation

We're training frontier AI to perform advanced consulting work, and we need experienced consultants to create and grade expert-level deliverables. You'll take on realistic engagements end-to-end — diagnose the problem, work through dense and sometimes conflicting source material, and produce (or evaluate) the kind of rigorous, decision-grade output a client would actually pay for.

### What you'll do

- Produce and review consulting deliverables such as: M&A / investment cases (EBITDA normalization, valuation, acquisition-debt structuring, covenant and sensitivity analysis, "proceed-with-conditions" recommendations); post-merger integration plans (synergy phasing vs. one-time costs, operating pro formas, integration narratives); and strategic / operational recommendations backed by quantitative analysis.
    
- Synthesize messy inputs — data rooms, due-diligence reports, memos, conflicting stakeholder guidance — into a clear, structured, well-reasoned case, correctly weighing more-credible vs. stale or distractor sources.
    
- Deliver client-ready work products: crisp memos, models, and recommendations with explicit assumptions, risks, and conditions.
    

### Who we're looking for

- 4+ years at a top consulting or advisory firm — MBB, Big-4 strategy & transaction advisory (TAS/TS), corporate strategy, PMI & operations consulting, or boutique advisory — or equivalent in-house corporate-development experience.
    
- Elite structured problem-solving and the ability to drive to a defensible recommendation under ambiguity.
    
- Strong financial and business acumen plus advanced modeling (LBO / 3-statement, pro forma) and executive-quality written deliverables.
    
- Comfort owning an engagement independently, not just supporting one.

**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).
