Senior Security Researcher | £90–100k |
Primarily Remote - 1 day a month in London (expensed)
We’re working with a high-growth cybersecurity product business looking to hire a Senior Security Researcher to join a specialist research team focused on cutting-edge threats and defensive capabilities.
This is a deeply technical role, ideal for someone who enjoys getting into the detail across malware, exploitation, and security research, while helping shape how products defend against real-world attacks.
It's not a typical blue team or red team role, it's a research-heavy position where you'll investigate real-world threats, build PoCs, and publish findings. They want someone who can operate independently, think like an attacker, but ultimately strengthen defensive capability.
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.
The role:
- Conduct deep-dive security research across threats, malware and attack techniques
- Perform static and dynamic analysis, reverse engineering, and PoC development
- Explore vulnerabilities, test exploitability, and design defensive solutions
- Work across research, engineering and product teams as a technical SME
- Produce high-quality technical write-ups, reports and whitepapers
- Present findings internally and externally (incl. conferences where relevant)
- Contribute to AI/agentic approaches to security research and analysis
What they’re looking for:
- Strong background in security research, malware analysis, or offensive security
- Hands-on experience with static and dynamic analysis tooling
- Solid coding ability (Python, C# or C++)
- Ability to take a problem from research → PoC → solution
- Comfortable working independently and owning research projects
- Strong communication skills — able to explain complex findings clearly
