Denver, CO

Prolific is building a large pool of quality human data used by AI developers, researchers, and organizations.

The role

We're looking for Senior Python Developers to help train and evaluate cutting-edge AI models. Candidates complete a short assessment and, if successful, join as participants to help AI understand and summarize complex scientific data.

Researchers looking for these skills tend to pay up to $50/hr, depending on skills and experience level. Tasks may require one hour of uninterrupted work, though many are shorter.

  • Real-world experience as a Senior Software Engineer/Developer specializing in Python
  • Ability to solve LeetCode Medium to Hard-level problems in Python independently
  • Expert understanding of the GIL (Global Interpreter Lock), decorators, generators, memory management, and asynchronous patterns (asyncio, async/await)
  • High standard for clean code, including modularity, readability, and adherence to modern Pythonic standards (PEP 8, PEP 20)
  • Ability to spot subtle logical flaws, memory leaks, or security vulnerabilities in model-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 in appropriate environments 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

  • Python 3.x with type hints and modern language features
  • Django, FastAPI, or Flask
  • pytest, unittest, coverage.py, and tox
  • RESTful APIs, GraphQL, and server-side Python development

Benefits

  • Competitive pay rates up to $50/hr depending on skills and experience
  • Flexible working hours
  • Remote work opportunities
  • Fast onboarding process after successful assessment
