Job description

Experience: 5+ years

Key responsibilities:

• Assess assigned packages, dependency trees, API-change exposure, build impact, and upgrade friction before execution.


• Upgrade Go modules and package versions; separate version bumps and local patches where required, and re-apply or retire patches safely.


• Resolve breaking API changes in the upgraded library and update directly affected downstream callers within the approved scope.


• Diagnose and remediate Go/Bazel build failures, existing test failures, and applicable presubmit failures attributable to the upgrade.


• Maintain Copybara configurations and troubleshoot source-synchronization or integration issues associated with the package change.

Required qualifications:

• 3-8 years of software engineering experience, including substantial hands‑on development and debugging in Go.


• Strong command of Go modules, semantic versioning, transitive dependency resolution, package compatibility, and idiomatic API refactoring.


• Practical experience with Bazel, go build, go test, CI/presubmit pipelines, and troubleshooting large or monorepo‑based build environments.


• Demonstrated ability to isolate compiler, linker, build, test, and runtime failures introduced by dependency upgrades.


• Proficiency with Git-based change management, code review, merge-conflict resolution, and local patch lifecycle management.


• Strong Linux and scripting skills for investigation, repeatable validation, and engineering automation.


• Clear written and verbal communication, disciplined documentation, and effective collaboration with reviewers and language SMEs.
