Protobuf Cleanup Engineer

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 $54/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.
• Bonus: Experience with GoGoProto and its ecosystem of extensions and options.
