I’m partnering with a global technology business that builds mission-critical software used across defence, government and complex operational environments.
They’re looking for a Senior Backend Engineer to join a high-performing engineering team working on a major long-term UK defence programme.
This is a genuinely interesting backend role with plenty of technical ownership. You’ll be building secure, scalable services, designing integrations across complex systems and helping shape the technical direction of a platform where reliability and quality really matter.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What they’re looking for
- ☕ Strong commercial experience with Java and Spring Boot
- 🔗 Experience building REST APIs, microservices and system integrations
- 🗄️ Strong SQL / PostgreSQL knowledge
- ⚡ Exposure to event-driven architecture, messaging or Kafka-style systems

Your very own career expert that helps elevate your application to the next level.
Experience in defence, government, national security, critical infrastructure or other regulated environments would be highly valuable.
You’ll suit this role if you enjoy working on complex systems, want meaningful technical ownership and care about building software that has a genuine real-world impact.
Due to the nature of the programme, applicants must be UK nationals and eligible to obtain UK Security Clearance. Active or lapsed SC would be a major advantage.
