  • Write clear, human-readable explanations of backend logic, architectural decisions, and code quality judgements
  • Identify edge cases, security vulnerabilities, and failure modes in AI-generated API logic
  • Provide structured, expert-level feedback that directly informs how AI models learn to write better code

Who You Are

  • Deep expertise in Python, including modern frameworks such as Django, Flask, and FastAPI
  • 3–5+ years of professional experience writing production-level Python code
  • Strong grasp of advanced Python language features, performance considerations, and software design principles
  • Exceptional written communication skills — you can explain complex technical concepts clearly and precisely
  • Bachelor's degree or higher in Computer Science or a related technical field
  • Self-motivated and comfortable working independently in an async environment

Nice to Have

  • Background in API security, distributed systems, or data engineering
  • Familiarity with software testing methodologies and edge case analysis

Why Join Us

  • Fully remote and flexible — work when and where suits you best
  • Freelance autonomy with the structure of meaningful, task-based work
  • Make a tangible impact on how AI understands, writes, and reasons about real-world code
