The work
You will review AI-generated C code, low-level systems designs, and technical explanations. Your reviews will focus on whether the work is correct, clear, safe, maintainable, and suitable for real systems.
You will also create reference implementations and step-by-step explanations for difficult engineering problems. The role includes comparing AI responses, finding subtle logic errors and undefined behavior, fact-checking technical claims, and helping improve model quality.
- Review C code, systems designs, and technical explanations for correctness and safety
- Find issues involving pointers, memory management, concurrency, performance, and low-level debugging
- Write reference implementations, technical explanations, and model solutions
- Rate and compare AI responses for correctness, clarity, and reasoning quality
- Identify undefined behavior and other subtle problems in systems-level C code
- Fact-check technical information and follow detailed project guidelines

About AI training work
AI training is the human work behind systems that learn from examples, including reviewing code and rating model responses. People with strong technical expertise are needed to show models what accurate, safe, and useful work looks like.
