What this actually is

You review AI-generated code, rank model outputs against each other, write prompts that test edge cases, and provide expert feedback that gets used to train coding models. Not shipping production software. The platform title (Chip Design Expert (RTL Design & Verification)) reflects the rate band and the expertise required, not the day-to-day work.

How Mercor picks people

  1. Upload your CV and answer the role's written questions.
  2. Do a video interview with Mercor's AI interviewer. Most take about 20 minutes, in English unless the role says otherwise.
  3. Some roles add a skills test. A test you pass once counts for similar roles.
  4. The project team reviews your results and sends offers to the people it picks.

Before you start

  • Take Mercor's free practice interview first. It does not count toward any application.
  • Use Chrome on a computer with a camera and microphone, in a quiet room.
  • You can retake an official interview up to 3 times, but hiring teams see how many times you retook it.

Not every applicant gets an offer. Prepare well for the interview.

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.
