About the Role

Build and extend capabilities across Optimum's internal omni-channel API platform — a Go gRPC backend deployed across GCP, AWS, and private cloud environments, serving Optimum's call-center, sales, and customer-support operations. You will own API and service delivery across multi-step workflows, with coordination across backend systems and presentation-layer consumers where appropriate.

Responsibilities

• Design and implement API capabilities using Go, gRPC, and Protocol Buffers that support business workflows across customer, order, billing, catalog, mobile, and related domains
• Develop and evolve service endpoints, orchestration logic, and integration layers across multiple backend and legacy systems
• 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

Requirements

• 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
• 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
• Background in telecom, billing, mobile, or e-commerce domains
• Exposure to Terraform or infrastructure-as-code practices
• Experience coordinating API delivery with frontend or client engineering teams
• Applicants must be authorized to work for ANY employer in the U.S.
