Job description
· Lead the design and development of scalable backend systems that support enterprise applications and integrations.
· Architect, build, and maintain RESTful and event-driven APIs for internal and external consumers.
· Design abstraction layers that expose functionality from legacy systems in a secure, modern, and reusable manner.
· Develop middleware services to translate, normalize, and orchestrate data between legacy platforms and modern applications.
· Integrate with legacy systems using available interfaces such as SOAP, REST, JDBC/ODBC, message queues, flat files, or proprietary APIs.
· Build API gateways and service layers that handle authentication, rate limiting, logging, and monitoring.
· Design and implement data transformation logic to map legacy schemas to modern domain models.
· Develop asynchronous processing pipelines using queues, event streams, or batch processing frameworks.
· Optimize backend services for performance, scalability, reliability, and fault tolerance.
· Implement caching strategies and database performance tuning techniques.
· Create robust error-handling and retry mechanisms for unstable or high-latency legacy endpoints.
· Ensure secure integration using OAuth2, JWT, mutual TLS, SAML, or other enterprise authentication mechanisms.
· Work closely with enterprise architects and infrastructure teams to modernize legacy integration patterns.
· Participate in system decomposition initiatives, including incremental migration from monoliths to microservices.
· Write comprehensive unit, integration, and contract tests to ensure API reliability.
· Document API specifications using OpenAPI/Swagger or similar standards.
· Implement logging, tracing, and monitoring using observability tools.
· Support CI/CD pipelines for automated builds, deployments, and environment promotion.
· Troubleshoot production issues related to system integration, performance bottlenecks, or data inconsistencies.
· Mentor junior developers on integration patterns, clean architecture, and backend best practices.
