Vulnerability Engineer - Remote

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
