Software Engineer - Entry Level

Mercor

Mercor is recruiting U.S./UK/Canada/Europe-based SWEs for a model-training project with a leading foundational model AI lab.

This is a contract role requiring around 20 hours per week, at least one month long, with pay of $100 per hour based on experience. Successful contributions increase the odds of being selected for future projects.

• Experience working at top U.S. 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).

The vetting process involves a 90‑minute technical interview conducted by a human, focusing on Python. LLMs or Stack Overflow can be used, but you will not be allowed to use an AI IDE. You will hear back within two weeks.
