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.
We’re looking for someone who fully enjoys working with and being around people, takes pleasure in triaging complex problems and is able to delegate and escalate tasks effectively. This role is anything but siloed; we’ll rely on you to be a key liaison between the IT Security team and other internal technology groups to distill and communicate pertinent information. While we’re open to individuals from a range of backgrounds, someone who’s worked in a code-driven environment and has hands-on experience with security incident response is preferred.
