Senior Java Software Engineer in Belfast

We are seeking an experienced, hands‑on Senior Java Engineer to join a newly established Deployment Security and Software Reliability Engineering team supporting one of the world’s largest financial institutions. This is not a traditional development, support, or operations role. You will work directly with development teams to make software releases faster, safer, and more secure, identifying what is preventing teams from releasing effectively and helping solve those problems hands‑on. The role is highly hands‑on, with a focus on Java, CI/CD, dependency modernization, automated testing, software supply‑chain security, containerization, release automation, and vulnerability remediation. Key Responsibilities Design, develop, troubleshoot, and improve enterprise Java applications and services. Work directly with development teams to identify and resolve technical barriers to safe and rapid software delivery. Improve and modernize applications through dependency upgrades and automated code transformation, using tools such as Renovate and OpenRewrite. Improve CI/CD build and release processes, including release branching, cascading merges, semantic or calendar versioning, and deployment automation. Build and improve automated, local, and smoke testing. Work with build and package ecosystems including Gradle, Maven, npm, and related tooling. Integrate and improve static code analysis, code quality gates, and application security scanning. Support integrations with tools such as Snyk, Black Duck, and Checkmarx. Work with SARIF, SBOM tooling, and CycloneDX to improve software supply‑chain visibility and security. Support and improve containerized and Kubernetes‑based application deployments. Troubleshoot complex issues across application code, dependencies, builds, configuration, testing, and deployment processes. Contribute to reusable engineering practices and automation that can be adopted across development teams. Required Skills
