Role OverviewMercor connects elite creative and technical talent with leading AI research labs. As a Backend Engineer, you will use frontier AI coding agents to complete and evaluate complex engineering tasks.
What You Will Do
Review model-generated code for correctness, quality, maintainability, and performance. Identify bugs, edge cases, and failure modes in model outputs. Compare outputs from multiple frontier models and assess their strengths and weaknesses.
Why It Might Be a Fit
You will work independently and asynchronously to meet deadlines while improving AI model performance. You will apply professional engineering judgment to realistic backend engineering scenarios.
Requirements
- 2+ years of professional backend engineering experience
- Experience building APIs, distributed systems, microservices, backend platforms, or databases
- Regular use of AI coding agents such as Cursor, Claude Code, Codex, Windsurf, Gemini CLI, or similar tools
- Ability to evaluate model-generated code and identify bugs, edge cases, and architectural tradeoffs
Benefits
- $400 per accepted task
- Typical tasks take approximately 1–3 hours after ramp-up
- No fixed task limits
- Compensation is tied to accepted work
