Job Description

Salary: $97,760 - 108,160 per year Requirements:

• 7+ years of software engineering experience; the target profile is 7–12 years.
• Strong, recent hands-on Go/Golang development and debugging experience, including idiomatic Go and API refactoring.
• Strong knowledge of Go modules, semantic versioning, dependency management, transitive dependencies, and package compatibility.
• Hands-on experience with Go build and Go test, plus Bazel and large-scale or monorepo build environments.
• Proven ability to troubleshoot compiler, linker, build, test, and runtime failures, including CI and presubmit issues.
• Experience with Git-based development, code reviews, change management, merge conflicts, and local patches.
• Strong Linux and scripting skills, analytical and problem-solving abilities, communication, documentation, and collaboration skills.
• Ability to work independently in a complex engineering environment.
• Must be able to work onsite in Bellevue, Washington, three days per week, beginning on day one; relocation candidates must confirm they can meet the onsite requirement.
• Candidates should be available to start within 1–2 weeks. We strongly prefer candidates authorized to work in the United States.
• Nice to have: Copybara or similar source-synchronization tools; open-source dependency upgrades; vulnerability remediation or package maintenance; complex dependency graphs; generated code and multi-target changes; high-impact API migrations; reusable upgrade playbooks or engineering automation; enterprise monorepos; and CI/presubmit infrastructure experience.

• Assess assigned packages, dependency trees, API changes, build impacts, and upgrade complexity.
• Upgrade Go modules and package versions, manage version changes and local patches, and reapply, update, or retire patches as needed.
• Resolve breaking API changes, update affected downstream callers, and address dependency relationships and compatibility issues.
• Diagnose and remediate Go and Bazel build failures, existing test failures, and compiler, linker, runtime, CI, and presubmit issues related to upgrades.
• Validate that upgraded packages build successfully and existing tests pass; creating new unit or integration test suites is not required.
• Maintain and troubleshoot Copybara configurations and source-synchronization issues.
• Use approved internal tools and reusable automation to analyze dependencies, triage failures, and support large-scale package migrations.
• Develop repeatable investigation, validation, and evidence-collection approaches.
• Submit review-ready changes with clear technical rationale and validation evidence.
• Document package versions, dependency remediation, validation results, patch status, migration records, deviations, and external blockers.
• Identify cross-product dependency impacts and communicate them to relevant stakeholders.
• Work with reviewers, engineering teams, and language subject-matter experts; communicate issues and blockers clearly and proactively.
• Provide actionable evidence when escalating complex issues, maintain progress against assigned priorities, and ensure clean handoffs with reusable technical learnings.

• API
• Bazel
• Git
• Golang
• Support
