Senior Java Engineer
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.
