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
