Systems Software Engineer

Job Summary

Join a high-impact engineering team responsible for the core metadata services that power a massive, distributed file storage system. This team owns the design and evolution of systems and database models that manage billions of files and directories, ensuring world-class performance, scalability, and reliability. As part of a critical modernization effort, we’re removing all usages of GoGoProto from our Protocol Buffers definitions. This work impacts the foundation of the platform’s file metadata model and service interfaces and is essential to improving long-term tooling compatibility, maintainability, and security. This is a unique opportunity to work at the heart of a large-scale, production-critical architecture, shaping the future of its core infrastructure.

Responsibilities

• Identify and remove all uses of GoGoProto extensions in existing .proto definitions
• Update protobuf schemas to use standard features and eliminate deprecated/custom behaviors
• Regenerate protocol buffer code using standard Go-compatible tools (protoc, protoc-gen-go)
• Refactor Go services to replace GoGoProto-dependent behavior (e.g., JSON marshalling, custom field options)
• Collaborate with engineering team members to validate functionality, ensure service continuity, and support active development
• Create documentation detailing the migration process, design decisions, and future maintenance guidance

Required Qualifications

• Solid experience working with Protocol Buffers and gRPC in Go environments
• Strong knowledge of protobuf code generation tools and workflows
• Demonstrated ability to understand, navigate, and refactor large-scale production systems
• Background in distributed systems and service-oriented architecture
• Ability to work independently, meet deadlines, and communicate effectively with technical stakeholders
• Bonus: Familiarity with GoGoProto and related ecosystem extensions

Project Impact

This migration is a critical milestone in reducing technical debt, improving codebase health, and aligning with industry-standard tooling. Your work will directly influence the stability, maintainability, and evolution of a large-scale metadata infrastructure that underpins file and directory services used at scale. You'll help ensure the system remains modern, robust, and efficient as it grows and evolves.
