• Protobuf Cleanup Engineer

    FocusKPI Inc. (San Francisco, CA)


    FocusKPI is looking for a Protobuf Cleanup Engineer to join one of our clients, a high-tech SaaS company.

     

    The team is looking for a contractor to help them remove all usages of GoGoProto (gogoproto) from their protobuf packages in the main live tier service. This work is part of a broader modernization effort, and the changes will significantly impact their metadata model and service interfaces.

     

    This migration is a key step toward improving their services' maintainability, tooling compatibility, and long-term sustainability and security. You’ll play a critical role in keeping the foundation of the client’s file metadata stack modern and reliable.

     

    Work Location: Remote - anywhere in the US

     

    Duration: 6-7 month contract

     

    Pay Range: $50/hr to $56/hr

    Responsibilities:

    + Identify and remove all uses of GoGoProto extensions in protobuf definitions.

    + Update .proto files to use standard protobuf features, replacing deprecated/custom gogoproto options where needed.

    + Regenerate protobuf code using standard tooling (protoc, protoc-gen-go, etc.) compatible with the Go/GRPC-based infrastructure.

    + Refactor Go services that rely on gogoproto-generated behavior (e.g., JSON serialization, custom options, field behavior).

    + Coordinate with the Filesystem team to validate changes, ensure compatibility, and integrate with ongoing development work.

    + Document migration steps and provide guidance for long-term maintainability.

    Qualifications:

    + Solid experience working with Protocol Buffers in a Go/GRPC environment.

    + Experience with GoLang is required

    + Familiarity with large-scale service-oriented architectures.

    + Strong understanding of code generation workflows and protobuf tooling.

    + Comfortable navigating and updating large, production-critical codebases.

    + Ability to work independently and communicate effectively with the team.

    + Having general problem-solving & troubleshooting skills is mandatory.

    + Bonus: Experience with GoGoProto and its ecosystem of extensions and options.
