Do you love turning complex cybersecurity challenges into compelling stories, impressive demos, and winning technical conversations?

Then look no further, and join us here at Hadrian as our new Senior Solutions Engineer!

Who are we?

What if cybersecurity could think like a hacker?

At Hadrian, that's exactly what we're building: the future of offensive cybersecurity, powered by autonomous AI agents that think like hackers. Founded in Amsterdam in 2021, we're on a mission to change the way organisations defend themselves by helping them find and fix security weaknesses before attackers can exploit them.

Our platform brings together two products: Atlas, which continuously maps an organisation's external attack surface and validates which exposures are genuinely exploitable, and Nova, which uses AI agents to perform in-depth penetration testing on demand. Together, they give security teams the visibility and proof they need to focus on what really matters and stay ahead of emerging threats.

Backed by $65M in total funding, including our recent $40M Series B led by Forgepoint Capital International and SmartFin, we're investing in the next generation of autonomous offensive security and expanding our impact across global markets. With a team spanning 25+ countries and offices in Amsterdam, London, and New York, we're helping organisations rethink what's possible in cybersecurity.

Join us and help shape the future of offensive security.
