Senior Networking Software Engineer

• Location: Kraków (hybrid or remote) / Poland
• Company: AI Hardware Startup

About the company

• Our client is a deep-tech AI hardware startup, founded in 2019 in Israel, building next-generation AI infrastructure.
• ~70 engineers globally, highly senior team
• Strong core R&D in Israel, growing hub in Kraków
• ~$70M total funding (Series A + follow-up rounds)
• Full-stack hardware & software development: from architecture to silicon bring-up
• The company develops a custom AI SoC, with a strong focus on high-performance networking and HW–SW co-design.

About the role

• We are looking for a Senior Networking Software Engineer to take a key role in designing and developing networking software for a complex AI SoC.
• This is a system-level, low-level role - focused on C, Linux networking, embedded systems, and HW–SW interfaces, not IT or enterprise networking.
• You will work closely with hardware, firmware, and architecture teams and be involved across the full product lifecycle.

Responsibilities

• 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

Requirements (must-have)

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
