Description

Senior Java Engineer Modern Platform | Greenfield Work | Collaborative Team Hybrid - 3 days onsite (flexible days) Up to £70,000 + benefits (some flexibility for the right person) We're working with a large, well-established organisation who are continuing to build out a modern, evolving platform that supports real-world operational processes at scale. This is a hands-on role within a pure in-house engineering team, offering a strong mix of delivery, collaboration, and technical influence. They're looking for a capable Java engineer who enjoys being close to the code, contributes thoughtfully within a team, and is comfortable working in an environment where delivery and improvement go hand in hand. The Opportunity You'll join a small, collaborative team working on a relatively new system that is still being shaped and evolved. The work includes a healthy mix of new feature development, iteration, and improvement, with room to influence how things are built without the pressure of owning everything. The balance between hands-on delivery and higher-level contribution naturally shifts depending on priorities - some weeks are delivery-heavy, others allow more space for refinement, learning, and improvement. While this role sits at a Senior level, the focus is less on title and more on capability, judgement, and how you approach problem-solving. What You'll Be Working On The platform supports a high-throughput operational environment, where software is used directly in day-to-day processes. This includes **Applications supporting workshop and operational workflows **Tablet-based interfaces used in live environments **Integrations with workforce and process management systems **Ongoing development of a relatively new, greenfield platform You'll be joining a team that values pragmatic engineering and steady improvement. Tech Environment The stack is modern and well-supported: **Java / Spring Boot (core focus) **React on the frontend **OpenShift / Kubernetes for most deployments **Full CI/CD pipelines in place **A growing amount of AWS-native development DevOps experience isn't a requirement. The priority is strong application development, with plenty of opportunity to broaden your skill set over time if you're interested. What They're Looking For **Solid, hands-on experience with Java and Spring Boot **Comfortable operating at a senior-capable level within a delivery-focused team **Someone inquisitive who asks questions and contributes ideas **Happy collaborating closely with other engineers, product and design **Experience with React is useful, but backend experience is the priority They're open to different strengths - whether that's delivery, system thinking, mentoring, or continuous improvement - as long as you bring good engineering judgement and a collaborative mindset. Working Pattern & Culture **Hybrid working - 3 days per week onsite (flexible days, team-aligned) **Teams primarily based in London, with cross-site collaboration **Supportive, low-ego engineering culture **Emphasis on good engineering practices and sustainable delivery Interview Process **Initial remote conversation **Technical exercise **Final onsite interview Interested? If you're a strong Java engineer looking for a senior-level role where you can contribute, learn, and have a real impact without being boxed into a single "type" of engineer, this is a great opportunity to explore.
