Full Stack Engineer

* Evaluate AI-generated code across the full stack — frontend (React, Vue) and backend (Node, Python, C#) — for correctness, quality, and best practices * Design and build full-stack tooling to support AI data annotation and quality control workflows * Review complex system designs and provide expert feedback on scalability, architecture, and performance * Identify subtle bugs, anti-patterns, and security issues in AI-generated code that automated tools miss * Provide structured, detailed technical feedback that directly improves how AI models generate and reason about code * Work independently and asynchronously — fully on your own schedule

Who You Are

* 3–5+ years of professional full-stack experience writing and shipping production code * Master's or PhD in Computer Science or a closely related technical discipline * Proficient across JavaScript/TypeScript, Python, and Rust * Strong command of both frontend and backend development — you're equally at home in a React component and a REST API * Exceptionally clear written communicator — you can explain complex technical decisions concisely and precisely * Detail-oriented and rigorous — you hold code to a high standard and can articulate exactly why

Nice to Have

* Experience with distributed systems, developer tooling, or CI/CD infrastructure * Familiarity with AI/ML workflows or LLM-based code generation tools * Background in code review, technical mentorship, or engineering leadership * Prior exposure to data annotation, prompt engineering, or AI evaluation platforms

Why Join Us

* Work on cutting-edge AI projects alongside the world's leading AI research labs * Fully remote and flexible — work when and where it suits you * Freelance autonomy with the structure of meaningful, technically challenging work * Make a direct, tangible impact on how AI understands and generates code at scale * Potential for ongoing work and contract extension as new projects launch
