Senior Software Engineer (Python/TypeScript) - AI Code Review, Contract

We're hiring senior software engineers for remote contract work with frontier AI research teams: designing and refining rubrics for AI-generated code, reviewing model outputs with a high bar for quality, catching subtle bugs others miss, and turning that judgment into clear write-ups and scalable evaluation pipelines. Real engineering judgment, not data labeling.
Pay: $60–100/hr depending on experience
Hours: 20–40 hrs/week (at least 4 hrs/day), about 3 months, starts within 1–2 weeks
Location: remote, must live in the US or Canada, 4 hours/day overlap with US Pacific time
Required:
- 5+ years of professional software engineering in Python (ideally building pipelines/infrastructure) or TypeScript / Go / JavaScript
- Hands-on experience with preference data, rubric creation, or AI/LLM evaluation
- Strong written communication: you can explain why something is good, not just that it is
- An up-to-date LinkedIn profile
Strongly preferred:
- Experience at top-tier tech companies and/or a degree from a top university
- Experience working in large codebases (e.g. VS Code-scale projects)
Note: we can't consider anyone currently employed at Microsoft.
How it works: a 2-minute application, a short technical screen, then ID verification. We check every résumé, LinkedIn and ID, so please apply with your real work history.
