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.
