Senior AI Security Engineer
Remote UK | Competitive Salary + Benefits
We're partnering with a fast-growing Cyber Security SaaS organisation that is transforming how enterprises identify and remediate security vulnerabilities through AI-powered automation. They're looking for a Senior AI Security Engineer to help build autonomous AI agents capable of planning, reasoning and executing sophisticated security workflows within tightly controlled environments.
This is a hands-on engineering role for someone who enjoys building products, solving difficult technical problems and owning delivery from concept through to production.
The Opportunity
You'll play a key role in designing and delivering AI agents that automate complex security testing activities, helping organisations identify vulnerabilities faster and more effectively. Working at the intersection of AI and Cyber Security, you'll collaborate with software engineers and security specialists to create intelligent systems capable of reasoning, planning and safely executing real-world security workflows.
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.
