We are seeking a Java Engineer to join our UK Digital Data & Cloud Practice. Our Digital Practice is expanding rapidly and you will have the opportunity to develop your career and technical skills. You will be working for one of our high‑profile trading clients within the financial services domain, contributing hands‑on to a Java‑based development team supporting a high‑volume message processing environment.

The team is heavily Java‑focused, operating within a client ecosystem that relies extensively on Kafka, Kubernetes/Open Shift, caching solutions, REST APIs, and high‑throughput distributed systems. You will bring solid, practical experience in backend Java development and a keen interest in scalable distributed systems.

• Design, develop, and maintain backend components in Java, with a focus on performance and resilience.
• Contribute hands‑on to features across messaging, caching, and distributed processing layers.
• Troubleshoot and resolve issues related to sequencing, recovery, message failures, and large‑volume processing.
• Support releases, deployments, and production stability activities.
• Adhere to CI/CD pipelines, code quality standards, and operational readiness requirements.
• Apply performance, security, and resilience best practices, particularly around message handling.

• Work closely with the Technical Lead and peers to deliver against team objectives.
• Contribute to technical discussions, design reviews, and knowledge sharing within the team.
• Raise risks, blockers, and progress updates clearly within the team.

• Some exposure to trading or financial platforms, with an awareness of non‑functional requirements such as latency, resiliency, throughput, and failover handling.
• Experience developing cloud‑native applications with a microservices architecture running on Docker/Open Shift/Kubernetes.
• Solid application development skills in Java, SQL (SQL Server, Oracle, etc.) and messaging platforms such as Kafka and MQ.
• Experience with the Spring framework and Spring Boot technologies.
• Experience in Java REST API development and application security best practices (OAuth, JWT, etc.).
• Experience with build and source control tools:
  Gradle, Maven, Git/Bitbucket.
• Familiarity with caching services such as Redis.
• Awareness of AI coding assistants such as Git Hub Copilot, Cursor, or Claude to accelerate development, generate boilerplate, and review code.
• Ability to apply AI tooling critically – validating, refactoring, and integrating AI‑generated code rather than accepting output uncritically.
• Awareness of prompt engineering techniques relevant to software development workflows.
• Experience working in an Agile/Scrum environment.
