Join our team

Do you like digging in the code (both source and machine one [e.g. x64/ARM64])? Do you have any experience in writing exploits and/or finding vulnerabilities in native code? Then come and join our team – we are quite like-minded. :)

No direct requirements - prove your skills in a direct way - references or on the spot (via interviews)
Where to start?

The best way to present your skill and prove your expertise is to pick any CVE (not a web application one), create an exploit, bring it for presentation. You may also convince us with your own 0-day. (This is optional.)

It is possible to work remotely if you prefer such an option.

We look forward to meeting you!
