Careers at TCS: It means more

TCS is a purpose-led transformation company, built on belief. We do not just help businesses to transform through technology. We support them in making a meaningful difference to the people and communities they serve - our clients include some of the biggest brands in the UK and worldwide. For you, it means more to make an impact that matters, through challenging projects which demand ambitious innovation and thought leadership.

The Role

We are seeking an experienced Java Developer to join us, designing and building Spring Boot services within a microservices architecture for a regulated banking environment. The role focuses on delivering secure, scalable APIs and event-driven components, collaborating with product and platform teams to implement well-engineered solutions across transaction-heavy systems. You will contribute throughout the software development lifecycle—analysis, development, testing, deployment, and production support—helping to modernise critical platforms and improve performance, resilience, and observability.

Key Responsibilities

• Design, develop, and maintain Java applications using Spring Boot, building RESTful APIs and microservices for high-volume banking platforms.
• Implement microservices patterns (service decomposition, resilience, circuit breakers, retries, idempotency) and ensure reliable inter-service communication.
• Collaborate with architects, product owners, QA, and DevOps to refine technical requirements, estimate work, and deliver features in Agile sprints.
• Build automated tests (JUnit, Mockito, integration tests) and contribute to CI/CD pipelines to enable frequent, reliable releases.
• Develop data access layers using Spring Data/JPA and SQL; optimise queries and persistence strategies to meet performance and scalability goals.
• Define and maintain API contracts (OpenAPI/Swagger), integrate with upstream/downstream systems, and ensure backward compatibility across releases.
• Apply secure coding practices (OAuth2/JWT, input validation, secrets management) and support security reviews in a regulated environment.
• Improve service observability using structured logging, metrics, and distributed tracing; troubleshoot incidents and perform root-cause analysis.
• Containerise services (Docker) and support deployments to Kubernetes/OpenShift and/or cloud platforms, following infrastructure and release standards.
• Promote engineering best practices (clean code, reviews, documentation) and contribute to technical design discussions to improve platform resilience and maintainability.

Your Profile

Essential skills/knowledge/experience :

• Strong hands-on experience in Java development (typically 5+ years), delivering backend services using Spring Boot in an enterprise environment
• Proven experience designing and building microservices (REST APIs, service-to-service communication, resilience patterns) and integrating with distributed systems
• Strong engineering practices including unit/integration testing (JUnit/Mockito), code reviews, and experience working with CI/CD pipelines
• Experience with data persistence and integration, such as SQL and ORM frameworks (JPA/Hibernate), and familiarity with messaging/event-driven patterns (e.g., Kafka/RabbitMQ)
• Comfortable working in Agile teams and in production environments, with exposure to containers/cloud (Docker/Kubernetes, AWS/Azure) and observability (logging/metrics/tracing)

Desirable skills/knowledge/experience: (As applicable)

• Experience with container orchestration and deployments (Kubernetes/OpenShift) and hands-on troubleshooting in production environments
• Cloud experience (AWS/Azure), including networking basics, IAM concepts, and working with managed services used by microservices
• Experience with event streaming/messaging and distributed data platforms (e.g., Kafka) and designing event-driven microservices
• Performance engineering experience (profiling, JVM tuning, latency analysis) and building resilient services under high throughput
• Exposure to financial services domain (banking/payments) and experience working with distributed, cross-functional teams on large-scale systems
