We are looking for Software Engineer, Go — Codebase Q&A candidates for a project delivered through Mercor.
What you'll do
- Select tasks from a pre-validated pool of Go 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
What you need
- 3+ years of professional software engineering experience, with substantial production Go
- Demonstrated ability to navigate a large, unfamiliar Go codebase and explain how it behaves at runtime — not just what the source says
- Fluency in Go concurrency, interfaces, module boundaries, and the standard library; comfort reading generated code and build tooling
- Precise written English: the questions and rubrics you write are the product
- Comfortable with git at commit level, containerized environments, and command-line tooling
Nice to have
- Experience with distributed systems, networking, storage engines, or Kubernetes-ecosystem tooling is highly relevant — the task mix is weighted toward architecture and system design (42%), code onboarding (26%) and root-cause analysis (20%)
