Senior Java Engineer – Event Driven Systems, Kafka

If you\’re a backend engineer who thrives on solving hard problems in distributed systems and you\’re looking for a role that actually matters, this one\’s worth a look.

We\’re working with a specialist team in the defencetech space scaling a brand new platform. Think live coordination, secure messaging, and data sync that holds up under pressure. It’s built for real-world, high-consequence environments.

Why:

• Low-latency, event-streaming architecture powering real-time decisions
• Greenfield core. This is a full rebuild, not legacy work.

What you’ll bring:

• Solid experience with Java and Spring
• Expertise in Kafka
• Strong grasp of performance, resilience, and secure system design
• Comfortable building in environments where quality, traceability, and uptime are critical
• Familiarity with identity platforms (like Keycloak), containerised deployments, and CI/CD pipelines

You’ll need to be eligible for UK Security Check clearance. That means 5+ years of UK residency and a clean background.

Nice to have:

• Experience with messaging or sync platforms
• Knowledge of geo-redundant or stateful deployments
• Exposure to security tooling, trust models, or encrypted transport layers
