Job description

• 5+ years hands-on software engineering experience delivering production systems in an enterprise or regulated environment.
• Strong proficiency in Java (17+) and Spring Boot, building microservices at scale.
• Solid experience with at least one front-end framework — React or Angular preferred — for building customer-facing digital journeys.
• Deep understanding of RESTful APIs, event-driven architectures (Kafka or equivalent) and integration patterns.
• Practical experience deploying services on Google Cloud Platform (GCP) or another public cloud (AWS / Azure), including Kubernetes / GKE, container images and Helm.
• Strong grounding in CI/CD, GitOps and Infrastructure-as-Code (Terraform).
• Test automation experience across the pyramid — JUnit, Mockito, Cucumber / RestAssured, Playwright or similar.
• Comfort with observability tooling — Splunk, Dynatrace, Grafana, Prometheus.
• Working knowledge of secure engineering practices — OWASP Top 10, secrets management, SAST/DAST integration in pipelines.
• Demonstrable use of AI-assisted development tools (e.g. GitHub Copilot, Cursor, Claude Code) and an appreciation of where they add — and don't add — value.
• Prior experience delivering into a UK Tier-1 bank or other regulated financial services environment.
• Exposure to Pega, Thought Machine Vault, or comparable core banking / BPM platforms.
• Experience contributing to platform / capability roadmaps and non-functional improvements (performance, resilience, cost).
• SC clearance (or eligibility to obtain).
