We are seeking a Senior Go Engineer to deliver complex third-party open-source package upgrades in a large monorepo environment.

Upgrade Go modules and package versions; separate version bumps and local patches where required, and safely re-apply or retire patches. Resolve breaking API changes in upgraded libraries 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 package changes. Use approved internal tooling and reusable automation to accelerate analysis, failure triage, validation, and evidence capture. Submit review-ready change lists with clear technical rationale, validation evidence, patch status, and traceable migration records. Document and escalate material package deviations, external blockers, and cross-product dependency impacts with actionable evidence. Required Qualifications
3–8 years of software engineering experience, including substantial hands-on development and debugging in Go. Robust command of Go modules, semantic versioning, transitive dependency resolution, package compatibility, and idiomatic API refactoring.
