- Improve reliability, performance, and safety across production Python codebases
- Integrate AI services and APIs with robust error handling and edge case coverage
- Identify bottlenecks and failure modes in data and system behavior, then implement scalable solutions
- Collaborate with data, research, and engineering teams to support model training and evaluation workflows
- Participate in synchronous design reviews to iterate on system architecture and implementation decisions
Who You Are - 3-5+ years of professional experience writing production-grade Python
- Strong full-stack developer with a solid systems programming background
- You write clean, maintainable code and naturally reach for linters, formatters, and comprehensive test coverage
