- Translate business requirements into Protocol Buffer contracts, Google AIP-aligned API designs, and reliable service implementations
- Expose platform APIs to internal consumer applications through well-defined service and gateway interfaces
- Address error handling, caching, and data consistency concerns across distributed service interactions involving Cloud Spanner, Redis, and related data stores
- Build and maintain automated tests using Go test frameworks to validate service behavior, integration paths, and contract expectations
- Support user-facing feature delivery through stable API contracts and collaboration with presentation-layer engineering teams
- Participate in platform modernization efforts, including migration from legacy integration patterns toward gRPC-based service delivery
- Contribute to code reviews, technical discussions, and continuous improvement of engineering practices within GitLab CI-supported workflows

- Understanding of service integration patterns, including synchronous communication and messaging approaches such as Pub/Sub or Kafka where applicable
- Experience with relational or distributed data stores such as Cloud Spanner, and familiarity with caching using Redis
- Proficiency with Git, code review practices, and GitLab CI or similar CI/CD pipelines
- Ability to troubleshoot issues across API and service boundaries
Preferred
- Experience with cloud platforms including GCP, AWS, and private cloud environments, and services such as Cloud Run, Cloud Spanner, Pub/Sub, and Redis
