Nexedi is looking for a C/golang developer interested in implementing a containerless process isolation system for SlapOS open source cloud computing platform.

The underlying ideas are explained in the article "Recent trends in process isolation technologies".

The underlying goal is to provide process isolation in SlapOS without containers. One possible application is "platform-as-a-service" isolation without VM or containers.

One implementation approach could consist - for example - of adapting gvisor to launch a Linux process within a user-mode kernel which isolates it from other processes.

Other approaches can ne considered.


  • Learn process isolation
  • Master Linux kernel ABI
  • Master C
  • Master golang


  • Contribute process isolation to SlapOS
  • Contribute to open source projects such as Linux, SlapOS, gvisor, etc.
  • Contribute to research projects to build the future of our open source stack


  • Passionate, self-driven.
  • Willingness to contribute to an open source ecosystem and the Free Software community.
  • Very good skills in GNU/Linux operating system.
  • Very good programming skills in C
  • Very good software development skills (version control, testing, debugging).
  • Good command of English.
