Senior Software Engineering Expert, AI lab project (Remote, Contract) — Mercor via AI Gig Scout

Mercor is working with a leading AI research lab on a project to improve how AI systems do real-world software engineering work, and is looking for senior software engineers with deep experience at top technology, quantitative or financial firms to train and evaluate frontier AI models. It is a remote contractor role listed at $120–$180/hr and 40 hours a week, open to candidates based in the United States, United Kingdom, Canada, Australia or New Zealand.

You will design realistic, challenging software engineering tasks drawn from real-world work (feature changes in large codebases, debugging and root-cause analysis, code review, system design and architecture decisions, codebase Q&A, technical documentation and planning); write task proposals explaining why each task is realistic, how it is verified and what makes it hard for current AI models; write reference solutions, tests and task-specific criteria covering correctness, architecture, maintainability, style and scope; assess AI-generated code and work alongside AI coding agents to judge where they succeed and fail; and iterate on structured feedback from senior reviewers.

Requirements: 4+ years of professional software engineering experience at a leading technology or quantitative firm (FAANG+, Magnificent 7+, top-tier quant funds or equivalent) with a mid-senior title (ML, infrastructure, data, security and quant developer roles may also qualify), at a top financial institution as a software engineer, or at a household-name high-growth tech company with a senior title (experience may be split across employers); strong command of at least one major language such as Python, Java, C++, Go, TypeScript or Rust, plus system design, testing, debugging and code review; proven ability to work in large, complex production codebases; excellent written English; and a Bachelor's degree from an English-speaking country.
