Design and implement networking software for a custom AI SoC
Develop Linux networking components and performance-critical data paths
Participate in SoC architecture discussions and definition of HW–SW interfaces
Work on embedded Linux and embedded cores in a high-throughput, multi-threaded environment
Support pre-silicon validation, bring-up, and post-silicon development
Collaborate with firmware, hardware, and system architects

BSc or MSc in Computer Science, Computer Engineering, or Electrical Engineering
Strong hands-on experience in C
Solid experience with Linux networking and networking protocols
Experience with embedded systems and HW–SW integration
5+ years of relevant software / system-level engineering experience
Nice to have
Experience with RDMA / RNIC
Experience with bare metal or firmware
Experience with PCIe, DMA, or device-level communication
Background in SoC, semiconductor, AI hardware, or networking silicon
Location & work format
Kraków: hybrid or remote (local hub currently forming)
Poland: remote
Close collaboration with Israel-based core R&D team
Why this role
Work on state-of-the-art AI hardware and networking technology
Very senior, low-ego engineering team
High impact on architecture and product decisions
Rare opportunity to work end-to-end: architecture → silicon → product
