5+ years writing production Python. You should be comfortable in a 5K+ line Python codebase, idiomatic with typing, pathlib, subprocess, pytest, and the subtleties of mocking at the import-site vs. the source-site (this will come up).

Deep familiarity with Docker, docker-compose, and the Dev Containers specification. You should be able to read a devcontainer.json plus its referenced docker-compose.yml and predict exactly which bind-mounts, setting variables, and lifecycle hooks will land inside the resulting container.

Comfortable across macOS, Linux, and Windows as both a user and a developer. Cross-platform shell quirks (PowerShell vs. bash, path-separator handling, symlink semantics, NTFS junctions vs. POSIX links) should be old friends,



not surprises.

Robust Git: worktrees, hooks, submodules, the difference between git rev-parse --git-common-dir and --git-dir, and exactly what git add -A will silently sweep into a commit.

A working understanding of at least one of: large C++ codebases (CMake/Bazel, distcc/ccache, NFS-backed build artifacts) or large Java codebases (Maven/Gradle, IDE indexing, build caches). You will not write application code, but you will need to read it and understand why a build is slow inside the container.
