Up to £115,000 + Bonus + Share Scheme + Staff Benefits
Fully Remote (UK)
SECURE has Strategically Partnered with a Multi-Award-Winning, Software-Based Organisation at the forefront of Pre-Emptive Exposure Management. As a market leader backed by significant venture funding, they are expanding their Offensive Security capabilities, specifically by scaling an Elite Vulnerability Research & Engineering Function across the globe.
Role Overview:
Step in as the highly technical Lead Vulnerability Engineer. Acting as a true Hybrid Researcher & Software Engineer, you will conduct original 0-Day & N-Day Research while Engineering the Production-Grade, LLM-Powered Tooling that Automates Exploit Validation. By hunting down Critical, High-Impact Weaknesses, you ensure their Clients Neutralise Vulnerabilities before Adversaries even strike.
Who Should Apply:
The Hybrid Researcher: An Elite Offensive Specialist who refuses to be boxed into a Single Domain. You can Audit Complex Web Applications for Authentication Bypasses in the morning, Reverse-Engineer a Firmware Patch in the afternoon & Write the Automated Detection Signatures by evening.
The Tooling Innovator: A Production-Grade Software Engineer with serious Offensive Security DNA. You don't just want to manually find Vulnerabilities; you want to Build the Automated, AI-Accelerated Tooling that scales your Research across an Internet-Wide Attack Surface.
Skills & Experience of Senior Lead Vulnerability Engineer:
Vulnerability & Engineering Experience (5+ Years): Proven Real-World Experience blending Elite Vulnerability Research with Production-Grade Software Engineering.
0-Day & N-Day Mastery: Demonstrated Track Record of Original 0-Day Discovery (CVEs, Public Advisories) & N-Day Patch Diffing - you regularly pull apart Binary Diffs & Build Working POCs before the Public Write-Up lands.
Web & Binary Fluidity: Deep Competence across both Web & Binary Vulnerability Classes, with Hands-On Expertise using Burp Suite, Ghidra / IDA, Debuggers & Fuzzers.
Elite Programming: Proven Experience Writing & Deploying Production-Quality Code used by Real Users, with a heavy emphasis on Python.
AI / LLM Integration: Practical, clear-eyed experience Designing & Implementing LLMs to tangibly accelerate your Own Research or Engineering Workflows.
Start-Up / Scale-Up Execution: A proactive, ownership-driven mindset capable of navigating ambiguity and shifting priorities within a high-growth, fast-paced scale-up environment.
Responsibilities:
Hunt: Conduct relentless Security Research across both 0-Days & N-Days, Reverse-Engineering Patches & Performing Analysis via Patch Diffing on Source-Available & Binary-Only Targets.
Engineer: Build & Maintain Robust, Production-Quality Internal Tooling for Automated Vulnerability Discovery, Exploit Validation & Scalable Detection Signature Generation.
Innovate: Design & Operationalise LLM-Powered Workflows that push the boundaries of Offensive Security & Exponentially Accelerate Research Output.
Target: Focus Exclusively on Critical, High-Impact Weaknesses that matter (eg Full System Compromise / RCE) rather than Generating Low-Level Informational Noise.
Evangelise: Present your Original Research to the Global Cyber Security Community at top-tier conferences, fully supported and sponsored by the business
