About the role
We are expanding our newly established SPM (Sustainability & Physical Markets) team with two AVP-level engineering positions. This is a rare opportunity to join at the outset of a significant build phase, delivering a three-year technology roadmap centred on migrating a legacy .NET estate to Java and re-architecting an existing monolith into microservices. You will have genuine ownership within a small, focused team.
The Java /.NET balance
This is a Java-first role with meaningful.NET exposure. Your day-to-day will be roughly 70% Java, 30%.NET. The Java work is where the platform is heading: new microservices, REST APIs, and data services built on Spring Boot. The.NET work is the legacy estate you'll help migrate, so genuine familiarity with .NET / C# is needed to read, maintain, and safely move those systems across, rather than just a passing awareness.
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.
Two positions are available under a shared job description:
- Full-stack Engineer: primarily back-end Java with some React.js
- Java Engineer with DevOps responsibilities
Technical environment

- .NET / C#: legacy systems undergoing migration to Java
- Kafka: as the transport layer
- Kubernetes with Helm charts on OpenShift (EKS/AKS equivalents considered)
- Python: advantageous (testing)
