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.
What you’ll need
Essential:
- Commercial experience delivering web, internal and external tests
- Strong internal testing skills (BloodHound, Rubeus, Snaffler, Responder or similar)
- Web testing with Burp Suite and supporting tools
- Ability to read code, spot vulnerabilities and write scripts or tooling
- Confidence presenting findings to clients and explaining them clearly
Nice to have:
- Interest in OPSEC-safe methods and moving towards red team work
- Phishing experience (GoPhish, Evilginx)
- Advanced or niche certifications, or working towards them
- Experience mentoring other testers
Get help with your application
Your very own career expert that helps elevate your application to the next level.
What’s in it for you
- Support towards advanced certifications, training on an in-house platform, and a clear path to progress beyond the role.
- Fully remote, with the office there if you want it.
