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.
In Return
You will develop the roadmap for Arm’s core interconnect and control subsystems, ensuring they are strategically aligned and technically validated across markets. While the initial focus is infrastructure, you will work across line of business and customers to ensure these foundational technologies are robust, driven, and reusable across Arm’s diverse product portfolio. Your ownership of requirement specs and roadmap rigor will ensure subsystem coherence across product generations — enabling Arm to scale from IP to complete system solutions.
