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.
This is a hands-on architecture role in a regulated financial services environment. You will work across the full breadth of the firm’s technology estate — from cloud platforms and APIs to identity systems, network infrastructure, and business applications — at a time when the firm is delivering significant transformation programmes and the threat landscape is evolving rapidly, including in areas such as AI, large language models, and autonomous agent frameworks.
