• Integrate with internal and external systems using established architectural patterns, including SOAP, GraphQL, and enterprise adapter approaches where applicable
• 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

Qualifications

• Bachelor's degree in Computer Science or equivalent experience
• 3+ years of professional software development experience building and maintaining backend systems or service-oriented applications
• Strong Go development skills and experience building production backend services
• Experience designing, building, or consuming REST or gRPC APIs in production environments
• Working knowledge of Protocol Buffers, contract-first development, and code generation 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
• Experience integrating with legacy enterprise systems via SOAP, GraphQL, or similar protocols
