Senior Vulnerability Researcher — Mobile (iOS / 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 iOS 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 (iOS 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 iOS 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 OffensiveCon / Hexacon / POC, PWN2OWN, 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.
