We are now looking for a visionary Principal Engineer to help define the next generation of our platform.
Why this role matters:
This is more than a leadership position. It's an opportunity to influence the architecture, scalability, and future direction of a truly global technology ecosystem.
You'll lead the technical vision for one of the most critical pillars in our Engineering organisation, our API platform, driving innovation across synchronous and asynchronous services built with REST, GraphQL, Kafka, and cloud-native technologies.
You'll work hands-on with modern engineering tools and practices, partnering with talented squads to solve complex distributed systems challenges at scale. From AI-driven engineering initiatives to highly observable event-driven architectures, this is a role for someone who thrives on building exceptional systems and empowering exceptional teams.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
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.
