## About the Role

* Strong Python skills: comfortable across many codebases, refactoring safely, writing well-tested library code
 * Deep familiarity with modern Python tooling: uv, pytest, ruff, static type checking (pyright/mypy), pre-commit

 * Lead cross-repo runtime and dependency upgrades (e.g. Python version migrations), keeping the ecosystem current and consistent
 * Standardize build and CI/CD across projects using GitLab pipelines: typecheck, lint, format, test, with pyright and ruff
 * Manage Python packaging and dependency resolution with uv (workspaces, lockfiles, private Artifactory indexes)
