Full description

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.
