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/OpenShift, 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.

Responsibilities

• Design, develop, and maintain backend components in Java, focusing 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.

Qualifications

• Some exposure to trading or financial platforms, with awareness of non‑functional requirements such as latency, resiliency, throughput, and fail‑over handling.
• Experience developing cloud‑native applications with a microservices architecture running on Docker/OpenShift/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 GitHub Copilot, Cursor, or Claude, and ability to validate and integrate AI‑generated code.
• Awareness of prompt engineering techniques relevant to software development workflows.
• Experience working in an Agile/Scrum environment.

Benefits

• Quarterly Performance‑Related Profit Share Scheme.
• Career progression and mentorship coaching through Strength in Balance & Leadership schemes and a quarterly Pathways Career Development programme.
• Flexible/remote working options.
• Financial wellbeing initiatives: pension, private healthcare cover, life assurance, financial advice and employee discount scheme.
• Wellbeing schemes: gym discounts, bike‑to‑work, fitness classes, mindfulness workshops, employee assistance programme, generous holiday allowance, enhanced maternity/paternity leave, marriage/civil partnership leave and special leave policies.
• Educational assistance, incentivised certifications and accreditations, including AWS, Microsoft, Oracle and Red‑Hat.
• Reward schemes: Annual Excellence Awards and a ‘Call‑Out’ platform.
• Environment, social and community initiatives for local fundraising and development opportunities.
