Vulnerability Researcher - Remote | Up to £135k + Benefits | UK, US, Australia, New Zealand
Our client is a deep-tech firm trusted by governments and defence organisations for the kind of work that doesn't make headlines. They specialise in solving the hardest problems in software and firmware security - from PAC, ASLR and CFI to encrypted firmware and beyond.
This isn't one for beginners or box-checkers. It's for engineers who enjoy making machines do what they weren't supposed to - and know the difference between understanding an exploit and building a reliable one.
Role Overview You'll join a close-knit, elite team working on advanced vulnerability research and exploit development across a range of complex targets, including mobile platforms, embedded systems, and non-trivial binaries. The role is fully remote and demands a high level of autonomy, skill, and commitment.
Core Responsibilities
Reverse engineering software and firmware to uncover security flaws
Developing and demonstrating proof-of-concept exploits
Analysing binary targets using tools like IDA Pro, Binary Ninja, or Ghidra

Proven expertise in vulnerability research and exploit development
Deep understanding of OS internals, memory models, and binary formats
Experience with static, dynamic, and symbolic analysis tools and techniques
