The job description
About the Role
What if your Python expertise could directly shape how the world's most advanced AI systems write and reason about code? We're looking for experienced Backend Python Engineers to evaluate AI-generated code, build complex algorithmic challenges, and help push the boundaries of what AI can do with software.
This is a fully remote, flexible contract role built for senior Python developers who want meaningful, high-impact work alongside cutting-edge AI research labs — on their own schedule.
What You'll Do
- Review and evaluate AI-generated Python code for correctness, efficiency, and adherence to PEP 8 and industry best practices
- Design and develop complex backend algorithmic solutions and data processing scripts that challenge AI reasoning at its limits
- 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
- Prior experience with data annotation, RLHF, or AI evaluation workflows
- Background in API security, distributed systems, or data engineering
- Familiarity with software testing methodologies and edge case analysis
Why Join Us
- Work directly with leading AI research labs on some of the most technically demanding projects in the field
- 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
- Potential for ongoing work and contract extension as new projects launch
