Senior Java Engineer - (UK- Remote)

Senior Java Engineer We are hiring a Senior Java Engineer to design and build cloud-ready, microservices-based applications for a major banking modernisation programme. You'll work in an Agile team delivering resilient, secure, high-throughput services that sit alongside — and increasingly replace — legacy back-end systems.

What you'll do

Design, build and maintain Java (17+) services using Spring Boot and a microservices architecture. Build and consume RESTful APIs; work with event/streaming and messaging (Kafka, RabbitMQ/JMS). Write clean, well-tested code — TDD/BDD, unit and integration testing (JUnit, Mockito). Containerise and deploy services (Docker, Kubernetes/OpenShift) through CI/CD pipelines (Jenkins/GitLab CI).

Integrate with relational and/or NoSQL data stores (Oracle/PostgreSQL; DB2 a plus given the estate). Contribute to solution design, code reviews, and non-functional concerns — performance, resilience, security, observability. Collaborate with architects, BAs, testers and product owners; support SIT/UAT and production releases.

Requirements

Essential skills 8+ years hands-on Java engineering. Strong, current Spring Boot and Spring ecosystem (Spring MVC, Data, Security). Proven microservices design and delivery in production. REST API design; messaging/streaming (Kafka or similar). CI/CD, Docker and Kubernetes/OpenShift; Git. Automated testing discipline (JUnit, Mockito; ideally contract/integration testing).

Comfortable in an Agile/Scrum delivery environment.
