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.
