Linux OS Engineer

We are building the most important cybersecurity technology since the invention of the Internet. VISS is creating the foundational hardware security layer that will protect every digital endpoint of the future. We are looking for a world-class Linux OS Engineer to take a leading role in developing our custom, immutable operating system. This role demands relentless execution, extreme ownership and a genuine desire to build something civilization-level. If you’re looking for work-life balance, predictable routines or comfortable, repetitive tasks, this is not the job for you.

• Proven experience with Linux systems, particularly immutable distributions

• Strong understanding of OS structure, the boot process, and bootloaders

• Hands-on experience with both x86 and ARM hardware platforms

• Proficiency in C/C++ is a must ; Rust is a plus

• Familiarity with computer networking principles

• Experience in embedded systems, cybersecurity, or hardware-level engineering is a significant plus

• Opportunity to shape the future of our Digital Civilization
