## About the role

An AI company building models for enterprise sales teams needs experienced sellers to show what great deal thinking looks like. You'll review realistic B2B deal rooms (account research, stakeholder notes, deal context) and write the analysis a strong AE or sales leader would bring into the room. Your work becomes training data for a sales-specialized model.

## What you'll do

- **Discovery prep:** pull out the details that matter for a specific prospect, form a pain hypothesis, and lay out what you would dig into on the first call
- **Current vs. future state:** summarize where the buyer is today, where they want to be, and the capabilities needed to get there
- **Exec briefs:** prep an executive for a meeting: the goal, their role, your read on the people across the table, and what they most need to know
- Each task is self-contained and takes roughly 15 to 30 minutes
- **Commitment:** about 10 hours/week for a short pilot, with more work likely if it goes well

## Qualifications

**Required:**

- 4+ years as an Account Executive, or as a first- or second-line sales leader (Director, AVP, VP), selling B2B software
- Experience at well-regarded software companies (for example Stripe, Plaid, Salesforce, ServiceNow or similar)
- Hands-on enterprise deal experience: discovery, multi-threading, exec alignment, mutual action plans
- Based in the United States
- Clear, concise written English

**Preferred:**

- Experience managing or coaching AEs on deal strategy
- Experience with large, multi-stakeholder enterprise deals

## What this is not

This is not a sales or quota-carrying role. You will not contact any buyers. You are writing the expert analysis a model should learn from.

Enterprise Sales Expert (AE / Sales Leader)

**Role overview**

Mercor is working with a frontier AI lab on chip design tasks used to train and evaluate AI models. We're looking for experienced RTL design and verification engineers to review these tasks.

Each task is a realistic hardware engineering problem, such as designing or fixing an RTL block or writing a testbench. It comes packaged with a specification, starting files, a reference solution and automated tests.

**What you will do**

- Review each task end to end: the spec, the starting files, the reference solution and the tests.
- Confirm the task is fair and solvable: the reference solution passes, and everything the tests check can be worked out from the spec.
- Find flaws: ambiguous specs, tests that let wrong designs pass or reject correct ones, leaked answers, and tasks that are easier than they look.
- Judge whether each task is hard enough to challenge today's best AI models.
- Write clear, specific feedback and suggested fixes, and help shape new task ideas.

**Who we are looking for**

- 5+ years of hands-on RTL design or verification experience in industry (semiconductor, FPGA, EDA or similar).
- Strong Verilog / SystemVerilog skills, and experience with simulation and testbenches.
- Able to read and reason about Python test code.
- A careful, skeptical reviewer who can explain in writing why a task is broken or too easy.

Nice to have: experience with open-source EDA tools (e.g. Icarus Verilog, Verilator, Yosys, cocotb), formal verification, or reviewing benchmarks for AI models.

**Details**

- Remote and flexible, about 15–20 hours a week.
- $100/hour.
- Starts immediately.

Chip Design Expert (RTL Design & Verification)

We're looking for semiconductor fab safety and emergency response experts to review and create expert content on fab hazards, emergency procedures, and safety documentation.

## Required

- 3+ years as an EHS engineer, emergency response team (ERT) member, fab facilities or sub-fab engineer, electrical safety engineer, or occupational health nurse/EMT
    
- Hands-on work inside an operating semiconductor fab, or fab-floor work for a semiconductor equipment or gas supplier
    
- Direct knowledge of fab hazards: toxic and pyrophoric gases, HF and wet chemicals, gas detection, cleanroom evacuation
    
- Last fab-floor experience within the past 8 years
    
- Not only office, audit, or compliance EHS work; not only construction or general-manufacturing safety without cleanroom or HPM exposure
    
- Writes clearly in English
    

## Preferred

- Responded to a real fab incident (gas alarm, chemical spill, evacuation, earthquake), or held an ERT lead / incident commander role
    
- Experience at a leading fab or equipment maker: TSMC, Intel, Samsung, Micron, GlobalFoundries, Texas Instruments, SK hynix, Applied Materials, Lam Research, KLA, Tokyo Electron, ASML
    
- Knows SEMI S2/S8/S22 tool-safety standards, NFPA 318, or facilities experience with utilities, abatement, gas cabinets, or tool hook-up
    
- Safety certifications such as CSP, CIH, ASP, HAZWOPER, or CHMM
    

## Details

- Remote, about 10 hours per week
    
- $85/hour

Most work is asynchronous and can be done in the evenings or on weekends, with occasional meetings with the lab's researchers as needed.

You'll be engaged through Cincinnatus LLC, 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 software engineering, code review, and open-source maintenance topics.
    
- Design challenging, realistic engineering tasks grounded in the open-source codebase the expert knows best, such as the features, refactors and bug fixes a maintainer would assign, and write accurate, well-structured reference solutions.
    
- Evaluate AI-written code, tests and grading rubrics against the repository's architecture, conventions and quality bar, and provide clear, written technical feedback.
    
- Build, run and test the project locally, including with Docker, to confirm that tasks, solutions and tests behave as intended.
    
- Write precise rationales that explain what a strong solution looks like and where AI-generated changes fall short.
    
- Collaborate with other subject matter experts to ensure consistency and accuracy in training data.
    

# 3\. Core Qualifications

- Maintainer (named in MAINTAINERS or CODEOWNERS, or 10+ PR reviews in the last 12 months) or core contributor (3+ substantive merged PRs in the last 12 months) of a widely used open-source project.
    
- The repository is 2+ years old, has real users and an active code review culture, and is primarily human-written.
    
- Years of sustained open-source contributions, with a public history that can be verified against the candidate's own GitHub account.
    
- Senior-level code review judgment, including the ability to critically assess AI-written code, tests and edge cases.
    
- Hands-on ability to build and run the project and its test suite locally, including with Docker.
    
- Ability to commit 30–40 hours/week as your primary work focus, with availability for occasional meetings with the lab's researchers. Given that time commitment, this role isn't a fit alongside a full-time job.
    
- Exclusivity: no work with another AI lab or AI training company, including other Mercor projects, during the engagement.
    
- Authorized to work in the country you live in.
    
- Able to complete any necessary background checks and confidentiality agreements before starting, and to work on a company-provided device to protect the security of information.

- Share what made integrations go well or badly: documentation, reliability, pricing, security and compliance review, and support.
    
- Give candid feedback on what you would want from vendors serving retail-investing products.
    

Please share only your own experience and opinions. You will **not** be asked for confidential or proprietary information about your employer.

- Work at a company that reaches **retail investors**, such as an online brokerage, investing app, robo-advisor, neobank with investing, wealth platform, or brokerage infrastructure provider.
    
- Work on the **retail product side**, not institutional, hedge fund, or asset management desks.
    
- Evaluated or integrated a **third-party API or AI vendor in the past 12 months** (or will soon).
    
- **Involved in choosing** the vendor (helped evaluate or shortlist), not only building it after the decision was made.
    

* * *

### Nice to Have

- Integrated market data, news, research, or AI chat features.
    
- Experience across different company sizes or seniority levels.
