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
