What You'll Be Working On

We are looking for someone to work on our flagship product, Polymorphing for Linux. Polymorphing serves each customer a unique polymorphic version of the upstream Linux repositories (Centos, Ubuntu, Alpine, SUSE, Debian, RHEL). Our packages use the same Open Source code as the official repositories, but are completely randomized. This means that everything inside the binaries – instructions, registers, and addresses are all unique. This ground-breaking product delivers a Linux system that is immune to memory-based attacks – even those that have yet to be discovered or disclosed!

To build and serve millions of packages per day we have created the largest Linux package build farm in the world and we are looking to grow our elite team of engineers to share our common goal: protect our commercial and government customers by delivering unique operating systems with the most reliable, scalable, cost-efficient, secure build farm and package repository serving system in the world.

Who We're Looking For

Are you a hands-on engineer that loves to break things? Does testing a ridiculously large matrix sound fun? Do you obsess over data?
