Senior Java Full Stack Developer

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.

Ready for your next big role to own and deliver high‑quality, secure full stack services (Java React JS) that meet business outcomes. You will set the bar for engineering standards, champion secure-by-design practices, mentor teammates, and ensure scope is delivered reliably, on time, and with clear operational ownership.

Your responsibilities:

• Deliver full-stack features end-to-end—building responsive React/Next.js user interfaces, designing clean API contracts, and implementing Java/Spring Boot services to support them.
• Work closely with product and UX to turn designs into intuitive experiences—contributing to component design, state management, accessibility and consistent UI patterns.
• Build, deploy and operate full-stack applications on AWS—optimising UI and API performance, and using logging/metrics/tracing to keep services observable and reliable.
• Design secure end-to-end integrations—covering browser-to-API authentication/authorisation, API gateway patterns, and data/storage interactions that meet performance and compliance needs.
• Strengthen CI/CD for both front-end and back-end—automating builds, tests, security scans and deployments to improve release frequency and confidence.
• Develop scalable APIs, microservices and event-driven flows (e.g., Kafka), ensuring stable contracts and versioning so front-end changes can ship safely and independently.
• Contribute to agile delivery across the stack—refining stories, proposing technical designs, and balancing UI/UX quality with API/service robustness.
• Own quality and outcomes end-to-end—writing well-tested code (unit/integration/UI tests), reviewing PRs across React/Next JS and Java, mentoring teammates if needed, and driving issues through to resolution in production.
