About the job
Mercor connects elite creative and technical talent with leading AI research labs. Headquartered in San Francisco, our investors include Benchmark , General Catalyst , Peter Thiel , Adam D'Angelo , Larry Summers , and Jack Dorsey .
Position: Software Engineer, Python — Codebase Q&A
Type: Contract
Compensation: $130 per approved task
Location: Remote
Role Responsibilities
- Select tasks from a pre-validated pool of Python repositories, each pinned to a specific git commit and arriving with an engineering question, positive and negative rubrics, foils, and a golden solution.
- Explore the repository until you genuinely understand the subsystem in question, including the relevant PR or issue history.
- Rewrite the task's question so it defeats frontier coding agents while remaining well-defined and fairly answerable.
- Adjust rubrics and foils so they reward correct reasoning and reject plausible-but-wrong answers.
- Run the full validation loop in Studio — Check, Golden, Run, Analyze — and iterate until every stage passes.
- Document your work in the task README and submit for expert review, addressing reviewer feedback on returned tasks.
Qualifications
Must-Have
- 3+ years of professional software engineering experience, with substantial production Python .
- Demonstrated ability to navigate a large, unfamiliar Python codebase and explain how it behaves at runtime.
- Fluency in Python internals that matter in real systems: import machinery, descriptors and metaclasses, async and event loops, packaging, and C-extension boundaries.
- Precise written English: the questions and rubrics you write are the product.
- Comfortable with git at commit level, containerized environments, and command-line tooling.
Preferred
- Experience with web frameworks, developer tooling, type checkers, or scientific/numeric libraries is highly relevant.
Compensation & Legal
- Payment is per approved task; every task is reviewed by a second engineer and a super reviewer before acceptance.
Application Process (Takes 20–30 mins to complete)
