We are seeking a senior Go engineer to deliver complex third-party open-source package upgrades in a large monorepo environment. The role owns the engineering path from package assessment and version change through dependency remediation, build and existing-test stabilization, applicable presubmits, change submission, and migration reporting.

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.

Use approved internal tooling and reusable automation to accelerate analysis, failure triage, validation, and evidence capture.

Submit review-ready change lists with transparent 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.

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.

Preferred experience:

Copybara or comparable source-synchronization tooling.

Large-scale OSS dependency upgrade, vulnerability-remediation, or package-maintenance programs.

Complex dependency graphs, generated code, multi-target changes, and high-impact API migrations.

Building reusable upgrade playbooks or automation within controlled enterprise environments.

Expected outcomes:

Accepted package upgrade: package builds pass, existing tests pass, applicable presubmits pass, and the change list is submitted.

Migration report: package/version details, code and dependency remediation, validation evidence, patch disposition, and documented exceptions.

Predictable delivery: early blocker escalation, clean handoffs, reusable learnings, and reliable progress against assigned priorities.
