Design, build, test, and maintain Java 17+ microservices for a banking modernization program. Develop REST APIs and messaging integrations, containerize and deploy services through CI/CD, integrate relational and NoSQL databases, and address performance, resilience, security, and observability. Participate in Agile delivery, solution design, code reviews, testing, and production releases while collaborating with architects, analysts, testers, and product owners.
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.

What you need to know about the Belfast Tech Scene
If asked to name the birthplace of the RMS Titanic, you might not say Belfast. Similarly, if asked to name Europe's leading destination for foreign direct investment in new software development, Belfast might not come to mind. Yet, both are true. The city has emerged as a tech powerhouse, recently ranked among the best in the U.K. for tech careers — especially for software developers. It also leads the U.K. with the highest percentage of software development jobs advertised.
