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.
The London team is an experienced group of Java and Scala developers, with a deep understanding of UI and UX design. We deliver our software using agile methodologies, and we encourage best practices such as TDD, code reviews and pair programming for knowledge sharing and learning. Our team owns all aspects of the features they work on, from designing solutions to meet customer or product requirements, through implementation, QA and delivery. Each team member works on every part of the system.
