You are a good fit if you:
- Have experience working at top US tech firms
- Proven track record of building and maintaining complex, production-grade Python systems — not just scripts or notebooks, but full-featured services, tools, or frameworks used in real-world environments.
- Deep understanding of Python language fundamentals, including advanced features like decorators, generators, async/await, context managers, and performance tuning (e.g., profiling, memory optimization).
- Experience designing modular, testable codebases, using modern Python tooling and best practices (e.g., FastAPI, Pydantic, type hints, dependency injection, unit/integration testing frameworks).
Interview Process:
- **The vetting process involves a technical interview conducted by a human; you will not be allowed to use an AI IDE (Integrated Development Environment) but you will be allowed to use LLMs or Stack Overflow**

- This contract is expected to last at least **1 month**
- Successful contributions increase the odds that you are selected on future projects with Mercor
