We’re hiring a Senior Security Engineer to join a growing SaaS scale-up, with a strong focus on hands-on security engineering, automation and cloud security.
You’ll use AI to build agents and automate security workflows, write scripts and tooling, secure a predominantly AWS (70%) / GCP (30%) cloud environment, and support vulnerability management and remediation. This is a build-focused role where you’ll have the freedom to experiment with AI, improve existing processes, implement security tooling and engineer scalable security solutions. This is the first security engineering hire so the role will initially be very broad and flexible, allowing you to specialise as the team grows.
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 with hands-on security engineering experience, strong cloud security knowledge, scripting/automation skills, and genuine hands-on experience using AI/LLMs to build or automate things.
