This is a great opportunity to join a high-growth tech team building the core services and applications that power a major cloud platform used across a global, high-profile customer base. We're specifically interested in speaking with senior software engineers with a strong foundation in back-end development (Java specifically) and exposure to cloud technologies. This is a role well suited for software engineers who like owning things end-to-end - from React SPAs to Java/Spring services, from infrastructure-as-code to production releases. If you enjoy problem-solving, learning fast, and leaving things cleaner than you found them, you'll fit right in. What you'll do The Senior Software Engineer will ship new features across the full stack - front end, back end, and the cloud that holds it all together. You'll run your own services: pipelines, deployments, monitoring, reliability You'll lean into automated testing to keep quality high and releases smooth Work closely with product, UX, architects, and platform engineers to deliver well-designed software. Contribute to improving CI/CD and the engineering playbook Tackle production issues with a cool head and a systematic approach Use AI-assisted development tools to boost speed and refine solutions Mentor peers and help raise the technical bar across the engineering organisation in Belfast and beyond. Keep an eye on emerging tech and get the chance to bring fresh ideas to the table What you bring Strong commercial experience in Java. While this will be more back-end leaning (ie. 70/30 split) you'll ideally have hands-on skills with React/TypeScript/Node and modern front-end frameworks. Solid automated testing practices Working knowledge of cloud platforms (AWS ideal), containers, and Kubernetes Confident with SQL and performance-aware query design Comfortable navigating CI/CD and automating the boring stuff The tech stack you'll touch Java, Spring Boot, React, Python, Terraform, Kubernetes, Jenkins, Postgres, DocumentDB, AWS.
