Position Overview
The Senior API/Backend Engineer is responsible for designing, developing, and optimizing robust backend services and API architectures that power our critical business applications. This role requires deep expertise in API design patterns, microservices architecture, database optimization, and modern backend development practices, with a focus on transforming existing monolithic applications into scalable, maintainable, and performant microservices and service-oriented architecture in our Azure environment. Key Responsibilities
Lead API modernization efforts. Collaborate with cross-functional teams to enable seamless integrations while ensuring optimal backend performance. Lead transformation from monoliths to service-oriented architectures (REST, GraphQL, event-driven). Design and implement scalable API gateways (rate limiting, authentication, routing). Establish API-first development with OpenAPI/Swagger and contract-first design. Apply microservices patterns: saga orchestration, CQRS, event sourcing. Build efficient data access layers with caching, pooling, and query optimization. Develop backend services with modern frameworks (.NET Core, Node.js, Python FastAPI). Implement message-driven architectures with queues/streams. Design resilient third-party integrations. Establish a service mesh for inter-service communication and load balancing. Implement error handling, retry, and circuit breakers. Key Outcomes
Achieve 99.95% API uptime through resilient service patterns, circuit breakers, and retries. Decompose monolithic applications into microservices, reducing coupling and improving deployment independence. Establish comprehensive API governance (versioning, documentation, contract testing) across services. Achieve sub-second response times for the 95th percentile of API requests. Improve database query performance by 40% through indexing, caching, and optimization. Reduce inter-service dependencies by 50% with event-driven architecture and clear domain boundaries. Lower MTTR to under 30 minutes with enhanced logging, tracing, and debugging. Increase API development velocity while maintaining backward compatibility. Core Responsibilities
