Software Engineering Expert

About this role

The research teams behind the best-known AI models come to Mercor for software engineering judgment they can't generate on their own. Your standards and expertise become the rubric that frontier AI is graded against. This is a standing listing for engineers who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week. New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins. **What the work looks like** We match engineers in the network to projects like: - Writing an engineering problem from a system you have shipped, with the requirements, the constraints, and the failure modes, plus the reference answer a model's attempt gets graded against - Grading model-written code and design: whether it handles the edge cases, whether the complexity is justified, whether the test actually exercises the behaviour it claims to - Flagging where a model's code passes review and would fail in production, given concurrency, scale, error handling, or what it costs to operate Software engineering listings on Mercor have posted at $70 to $150 an hour, set per project by scope and depth. **What we're looking for** - Professional experience building and shipping software - Clear written communication, since most of the work involves explaining your reasoning - Comfort with ambiguous tasks, and willingness to flag unclear instructions **What this covers** This pool spans software engineering, including: - Frontend (React, TypeScript, Next.js); backend (Java, Go, Node.js); full-stack - Mobile (Android, iOS); embedded and IoT - DevOps and platform engineering; systems and performance engineering - QA and automation; security engineering Where you trained matters less than whether you have owned code in production and dealt with what it did there. **How it works** Apply here with your resume and confirm wher
