About the role

  • 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.

Requirements

  • 7–10+ years of experience in backend software development.
  • Strong proficiency in one or more backend languages such as Java, C#, Python, or Node.js.
  • Deep experience designing and building RESTful APIs and microservices.
  • Proven experience integrating with legacy enterprise systems.
  • Experience working with SOAP services, XML, JSON, and enterprise messaging systems.
  • Strong understanding of relational databases (SQL Server, Oracle, PostgreSQL) and query optimization.
  • Experience with NoSQL databases and caching technologies such as Redis.
  • Knowledge of API security standards and enterprise authentication mechanisms.
  • Experience with containerization technologies such as Docker and orchestration platforms such as Kubernetes.
  • Familiarity with API gateways, service meshes, and middleware platforms.
  • Experience implementing asynchronous communication patterns using Kafka, RabbitMQ, or similar technologies.
  • Strong understanding of distributed systems, scalability, and resilience patterns.
  • Experience working in regulated or high-availability enterprise environments preferred.
  • Strong analytical and troubleshooting skills with the ability to navigate complex system dependencies.
