About You:

You’re an experienced backend engineer who thrives in collaborative environments and enjoys solving complex technical problems. You’re confident in your skills with Java and bring solid experience with microservices, messaging systems, and scalable architecture. You’ve likely worked in fast-paced environments and know how to strike the balance between delivery speed and long-term maintainability.

You’re someone who:

• Thinks deeply about software design and architecture.
• Can clearly articulate your thinking to both engineers and non-engineers.
• Enjoys mentoring, supporting teammates, and fostering a strong engineering culture.
• Has a curiosity for emerging technologies and is eager to learn (and teach).
• Feels comfortable working independently, taking initiative, and owning solutions end-to-end.
• Believes in writing clean, testable code and values continuous improvement.

This is a great opportunity if you're passionate about impactful work, value autonomy and collaboration, and want to help build systems that matter.

About The Team:

You’ll be joining a small but mighty cross-functional engineering team within Collaboraite, focused on developing a collaborative data and analytics platform. The work involves cutting-edge challenges; real-time event handling, secure data ingestion, working with LLMs and Computer Vision models, and crafting high-performance indexing and search pipelines.

About The Role:

We’re hiring a Senior Java Engineer to join our Collaboraite team, building the next generation of secure, high-performance, and scalable data analytics platforms. This is a hands-on engineering role with real scope for technical leadership. You’ll help design, build, and deliver features and services that power AI-enabled products used by some of the most respected organisations in the UK.

Key Responsibilities:

• Build and maintain scalable, secure, and high-performance backend systems using Java, with additional exposure to Go and Python.
• Contribute to architectural decision-making and ensure alignment with engineering best practices.
• Build APIs and services in a microservices ecosystem, often using Spring Boot, Quarkus, and modern messaging systems.
• Support CI/CD practices, including infrastructure as code, containerisation, and GitHub Actions or Jenkins.
• Collaborate cross-functionally with Product, ML Engineers, and Designers to define, plan, and deliver features.
• Mentor junior engineers and champion best practices in testing, documentation, and code quality.
• Troubleshoot performance and reliability issues across distributed systems.

Success in This Role Looks Like:

• Delivering robust, scalable, and secure features that contribute directly to the platform’s growth and stability.
• Influencing technical direction by contributing to architectural decisions and raising the standard of engineering quality across the team.
• Proactively identifying improvements in system performance, developer experience, or technical debt—and driving them through to implementation.
• Mentoring and supporting team members, fostering a culture of collaboration, continuous learning, and engineering excellence.
• Communicating effectively with stakeholders across disciplines, translating complex technical ideas into clear, actionable insights.
• Taking ownership of projects and features from design through to deployment, monitoring, and refinement—delivering value quickly without compromising maintainability.

What We're Looking For:

• 7+ years of hands-on backend engineering experience, with deep expertise in Java and modern backend ecosystems.
• Proven experience building microservices and event-driven systems (e.g., with Kafka, RabbitMQ, or NATS).
• Strong relational database skills (PostgreSQL), including schema design and SQL optimisation.
• Experience with RESTful API design and implementation, ideally with Spring Boot or Quarkus.
• Familiarity with containerisation (Docker, Kubernetes, Helm) and DevOps practices.
• Comfortable working in Agile, cross-functional teams.
• SC clearance (or eligibility to obtain it) is a requirement for this role.

Soft Skills:

• Clear communicator who can explain technical concepts to both technical and non-technical stakeholders.
• Natural mentor who shares knowledge and brings others along.
• A thoughtful engineer who balances speed with maintainability.
• A proactive mindset—always looking for ways to improve systems, codebases, or processes.
• Ability to break down complex problems and drive solutions through to delivery.

Security Clearance Requirements:

Please note that holding current SC clearance is not essential at the point of application, but eligibility is required. This role requires the successful candidate to be eligible for Security Check (SC) clearance. To meet this requirement, applicants must:

• Have the right to work in the UK
• Have lived in the UK continuously for the past 5 years
• Not have spent more than 6 months outside the UK in total during that period
• Be willing to undergo security vetting as part of the onboarding process.

Please note that the talent acquisition team is managing this vacancy directly and we do not require agency support. Candidates who are successful will be required to undergo relevant security checks.

Our Process:

Our talent acquisition team will be in touch if you're successful, and the team will arrange a short screening call (max 30 minutes) to learn more about you, what you’re looking for, and answer any questions you may have. If all goes well, the team will share your profile with the hiring manager for review. Our interview process is tailored to each role but typically the first half is run remotely with a final stage on-site. For this position, you can expect a two-stage interview process:

• 1st Stage – An informal 30-minute video call with the hiring team to discuss your skills and relevant experience. This is an excellent opportunity to learn more about the role and ask any questions.
• 2nd Stage – A 60-90-minute formal interview where you can anticipate competency and technical questions. Depending on the role, there may also be a short take-home technical exercise or a virtual pair programming task to complete.
