Senior Vulnerability Researcher — Mobile (i OS / Android)
The work
You’ll spend your days where few researchers get to operate: deep inside modern mobile operating systems, finding what others assume is unbreakable. Reverse engineering, vulnerability research and full exploit development on i OS and Android — kernel, userland, baseband, firmware. Real research, on real targets, with the time and freedom to go as deep as the problem demands.
This is not pentesting, not red teaming, not a dashboard. It’s the hard version of the craft: understanding a system better than the people who built it, and turning that understanding into working capability.
What you’ll do Research and exploit vulnerabilities across modern mobile OS internals (i OS and/or Android).
Develop exploits and proof-of-concepts, from single primitives to full chains.
Build the tooling that pushes the whole team’s research further. What we look for A serious offensive background — you’ve done real vulnerability research, not just assessed other people’s security.
Hands-on mobile exploitation on i OS or Android (one is enough,



both is a bonus).
Found real vulnerabilities (0-day or 1-day), and know what it takes to weaponize them.
The temperament the work demands: resilient, comfortable starting from zero, able to spend weeks on something that might not pan out — and come back the next day. Nice to have
CVEs, published research, talks at Offensive Con / Hexacon / POC, PWN2 OWN, top-tier CTF. We care about what you can do, not how loud you are about it — strong researchers with zero public footprint are very welcome.
Why this one is different A small, elite team where everyone is genuinely world-class — you’ll learn every week.
Research you can’t do anywhere else, with the depth and patience this craft actually needs.
Compensation open to the market — base + bonus + bug bounty — set for the person, not the grid.
Full relocation and visa support. We move the right people, wherever they are.
Work that matters, for clients who depend on it. #J-18808-Ljbffr
