We are seeking an experienced Senior Java Engineer to join our UK Digital Data & Cloud Practice. Our Digital Practice is expanding rapidly and you will have the opportunity to achieve medium and long-term career goals. 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 deep, practical experience in scaling systems that process millions of messages per day and strong problem-solving capability across complex backend challenges.
Responsibilities
* Design, develop, and maintain high-quality backend components in Java, with a focus on performance and resilience.
* Contribute hands‑on to complex 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 large-scale 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
* Experience working on trading or financial platforms that process millions of messages per day, with strong awareness of non-functional requirements such as latency, resiliency, throughput optimisation, failover handling, and backpressure management.
* Experience designing and developing cloud-native applications with a microservices architecture running on Docker/OpenShift/Kubernetes.
* Strong 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.
* Experience with caching services such as Redis.
* Awareness of AI coding assistants such as GitHub 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 (code generation, test writing, documentation, debugging).
* Experience working in an Agile/Scrum environment.
Benefits
* Share in our success with our Quarterly Performance-Related Profit Share Scheme, where employees collectively benefit from a share of our company’s profits.
* Strong career progression & mentorship coaching through Strength in Balance & Leadership schemes with a dedicated quarterly Pathways Career Development programme.
* Flexible/remote working – the company is tremendously understanding of life events and people’s individual circumstances and offers flexibility to help achieve a healthy work‑life balance.
* Financial wellbeing initiatives including pension, private healthcare cover, life assurance, financial advice and an employee discount scheme.
* Employee wellbeing schemes including gym discounts, bike‑to‑work, fitness classes, mindfulness workshops, employee assistance programme and much more, plus 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 including the company’s Annual Excellence Awards & ‘Call‑Out’ platform.
* Environment, social and community first initiatives – allow you to get involved in local fundraising and development opportunities as part of fostering diversity, inclusion and belonging.
