  • High standards for clean code, including modularity, readability, and adherence to Python standards such as PEP 8 and PEP 20
  • Ability to identify subtle logical flaws, memory leaks, or security vulnerabilities in generated code

What you'll be doing in the role

  • Review AI-generated Python code for functional correctness and adherence to best practices
  • Audit AI explanations for complex algorithmic solutions to ensure logical accuracy
  • Execute model-generated scripts to verify performance and output
  • Identify inefficient solutions, deprecated syntax, or hallucinated library methods
  • Provide structured feedback on backend architecture, data pipelines, and API design discussions

Key Technologies

  • Expert-level Python 3.x including type hints and modern language features
  • Experience with Django, FastAPI, or Flask
  • Proficiency with pytest, unittest, coverage.py, and tox
  • Strong understanding of RESTful APIs, GraphQL, and server-side Python development

  • Flexible hours
  • Remote work opportunity
  • Fast onboarding process after assessment
