In this position, you will join the Python Infrastructure and Performance (PIP) team, which currently consists of two members and the team lead. The team’s vision is a codebase that we would be proud to open-source. The team cares a lot about doing things properly and sets high standards in their work in terms of maintainability, performance, and security. Taking a broader view, this team is responsible for improving the codebase on a systemic level, writing proposals for architectural changes, and facilitating discussions with other development teams (the primary customers).
Continuously improve the maintainability and quality of our Python codebase.
Example: modeling all the requests and responses in our HTTP endpoints
Remove technical debt by modernizing legacy code, upgrading dependencies and carrying out large-scale migrations and refactoring.
Example: migrating Pydantic from v1 to v2
Monitor and improve the performance of our API endpoints and of our background jobs.
Example: rewriting performance-critical code in Rust
Improve the performance and correctness of our test suite.
Work on security improvements together with other security specialists in the company.
Examples: Single Sign-On, security improvements to authentication tokens

Libraries: pydantic, sqlalchemy, typing, requests, logging, flask, fastapi, pytest
Tools: mypy, ruff, Sentry, Prometheus, Grafana, Loki
You are committed to high engineering standards; you care about making things robust and easy to maintain. Making other developers' lives easier makes you happy.
You don't just want things to work: you also want to understand how and why they work. You love diving deeply into technical details and finding creative solutions to complex problems. You can be pragmatic, but also truly enjoy doing things the right way.
