Vulnerability Engineer | High-Growth Cybersecurity Scale-Up | Fully Remote (UK)
*Remote – UK Based
*£85,000 + benefits
*Permanent – Full time
Want to spend your days hunting the vulnerabilities that actually matter – the RCEs, the auth bypasses, the bugs attackers will weaponise tomorrow?
Join a research-driven, venture-backed cybersecurity scale-up trusted by Fortune 500 enterprises and critical infrastructure providers. Recognised by Gartner, $29M funded, and scaling fast worldwide.
As a Vulnerability Engineer, you’ll sit at the intersection of vulnerability research and software engineering – finding bugs, building tools, and pushing the limits of LLM-powered offensive security workflows.
What you’ll be doing:
*Hands-on research across 0-days and n-days, with patch diffing on source-available and binary-only targets
*Building internal tooling for automated vulnerability discovery, exploit validation, and detection
*Implementing production-grade, LLM-powered research workflows
*Hunting the vulnerabilities that have real material impact – RCEs, auth bypasses, deserialisation bugs
What they’re looking for:
*2+ years of hands-on vulnerability research experience
*Familiarity with n-day reproduction and patch diffing
*Exposure to both web and binary vulnerability classes
*Software engineering experience, ideally in Python
*Comfort with Burp Suite, Ghidra/IDA, debuggers, fuzzers
*Genuine interest in using LLMs to accelerate security workflows
