Job Description:
Principal Vulnerability Engineer | High-Growth Cybersecurity Scale-Up | Fully Remote (UK)
*Remote – UK Based
*Up to £110,000 + benefits
*Permanent – Full time
Got a track record of 0-day discoveries, public CVEs, and a reputation for finding bugs that actually move the needle?
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 Principal Vulnerability Engineer, you’ll own the full vulnerability lifecycle – from discovery, through detection, to deployment – building production-grade tooling and pioneering LLM-powered offensive security workflows.
What you’ll be doing:
*Leading deep research across 0-days and n-days, with patch diffing across source-available and binary-only targets
*Designing tooling for automated vulnerability discovery, exploit validation, and detection signature generation
*Architecting production-grade, LLM-powered research workflows
*Focusing on the vulnerabilities that matter – RCEs, auth bypasses, the bugs that change a client’s risk posture overnight
What they’re looking for:
*5+ years of mixed vulnerability research and software engineering experience
*A demonstrable track record of original 0-day discovery – public advisories, CVEs, or equivalent
*Deep n-day research and patch diffing chops
*Confidence across both web and binary vulnerability classes
*Production-grade software engineering experience, ideally in Python
*Mastery of Burp Suite, Ghidra/IDA, debuggers, fuzzers
*Hands-on experience using LLMs in research workflows
*Remote – UK Based
*Up to £110,000 + benefits
*Permanent – Full time
