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.
It searches the market for you
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 we’re looking for
You will ideally have strong commercial experience with:
- Java and Spring Boot
- Angular and TypeScript
- SQL and relational databases, ideally PostgreSQL
- REST APIs, microservices and system integrations
- Automated unit, integration and end-to-end testing
- CI/CD and modern software delivery practices
- Docker, Kubernetes or containerised environments
- Cloud platforms such as AWS, Azure or GCP
- Agile software development
- Taking ownership of complex technical problems
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Experience with Kafka, RabbitMQ, event-driven architecture, ERP integrations, data platforms or legacy modernisation would be highly valuable.
Previous work within defence, government, national security, critical infrastructure or another highly regulated environment would be advantageous but is not essential.
The opportunity
This role offers:
- Salary of up to £120,000
- A long-term and technically challenging programme
- Genuine influence over engineering and architecture
- Work that has meaningful operational impact
- Collaboration with experienced UK and international engineering teams
- The opportunity to remain hands-on while mentoring and influencing others
- Hybrid working around Warminster and customer sites
Due to the nature of the programme, applicants must be UK nationals and eligible to obtain UK Security Clearance. Active or lapsed SC clearance would be a significant advantage.
