System Software Engineer

Belgrade, Serbia

We build software that runs close to the silicon — and we need an engineer who's comfortable there. As our Operating Systems Engineer, you'll work on Linux kernel development, OS performance, drivers, and the infrastructure that ties it all together. On these projects, you will have a chance to work with globally recognized experts in this area! 

 

How You’ll Contribute... 

  • Work on Linux kernel components, drivers, and system-level code for performance-critical services  

  • Profile and optimize OS-level behavior using perf, ftrace, eBPF, and similar tools  

  • Develop and maintain low-level components, including memory management and scheduling-adjacent work  

  • Debug complex system behavior — race conditions, latency spikes, interrupt handling 

  • Help others to succeed and grow 
     

Required skills: 

  • BSc/MSc in Computer Science, Engineering, Mathematics, or related discipline 

  • Strong programming skills in C/C++ or Python in Linux environments using common development tools 

  • Understanding of Operating system internals 

  • Hands-on experience with low-level software development (drivers, bootloaders, HAL libraries, etc.) 

  • Fluent in spoken and written English 

  • Methodical debugging mindset and comfort navigating large codebases 
     

You are a great fit if you have: 

  • Hands-on experience with Linux kernel development 

  • Deep knowledge of operating system internals 

  • Experience with debugging and system observability tools (GDB, LLDB, perf) 

  • Prior work with containerization or virtualization at the kernel level
