Senior Java Engineer

This is a remote position.

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.
