The Work

As a C Quality Assurance Lead, you will review AI-generated C code and trainer QA work across C programming AI training projects. You will assess whether code compiles, runs correctly, handles memory safely, follows instructions, and meets the project rubric.

  • Review C code, debugging responses, pointer and memory examples, algorithms, tests, and technical explanations.
  • Check correctness, compilation, runtime behavior, memory safety, pointer logic, portability, performance, readability, formatting, and rubric adherence.
  • Identify memory leaks, use-after-free issues, invalid pointer arithmetic, race conditions, unsafe recommendations, and other correctness problems.
  • Monitor quality, escalate critical issues, and provide clear feedback to contributors.
  • Support contributor communication, question handling, activation follow-up, and onboarding.
  • Maintain style guides, trackers, FAQs, examples, honeypots, calibration tasks, and quality documentation.
