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 looking for a fast-paced workplace that constantly pushes you outside your current skill set? Our engineers are responsible for designing, coding, testing, deploying and production support; we don't have dedicated operations or test engineers.

  • have 5+ years of experience developing on production systems
  • have designed and implemented production REST APIs
  • have excellent verbal and written communication skills
  • are a great teammate with strong analytical, problem solving, debugging, and troubleshooting skills
  • are proficient in operating and managing Linux
  • have engineered production workloads for AWS (or another cloud provider)
  • tend to obsess over code simplicity
  • strive to create simple and focused microservices
  • have a Github account that shows your chops

Bonus Points If You...

  • are fluent in Go (our primary language) and/or Rust
  • have experience with container technologies such as Kubernetes and Docker
  • have production experience with ECS/Fargate and DynamoDB
  • have experience interfacing with 3rd party authentication systems or you are experienced in authentication
