About the role
We are seeking a Principal Linux Driver Engineer to lead the architecture, design, and development of Linux kernel drivers and low-level networking software for the Slingshot high-performance interconnect. This role is responsible for software that enables and optimizes communication across next-generation HPC and AI systems, including network interface controllers (NICs) and fabric switching technologies. As a senior technical leader, you will work closely with ASIC, hardware, firmware, and system software teams to bring new products from architecture through deployment. You will drive software that delivers the performance, scalability, reliability, and observability required by some of the world's largest supercomputing and AI clusters. This is a hands-on technical leadership role requiring deep expertise in Linux kernel development, network driver architecture, high-performance networking, and complex hardware/software integration. "The expected salary/wage range for this position is provided below. Actual offer may vary from this range based upon geographic location, work experience, education/training, and/or skill level.
