Principal Kernel & Device Drivers Engineer

The era of pervasive AI has arrived. In this era, organizations will use generative AI to unlock hidden value in their data, accelerate processes, reduce costs, drive efficiency and innovation to fundamentally transform their businesses and operations at scale.

SambaNova Suite™ is the first full-stack, generative AI platform, from chip to model, optimized for enterprise and government organizations. Powered by the intelligent SN40L chip, the SambaNova Suite is a fully integrated platform, delivered on-premises or in the cloud, combined with state-of-the-art open-source models that can be easily and securely fine-tuned using customer data for greater accuracy. Once adapted with customer data, customers retain model ownership in perpetuity, so they can turn generative AI into one of their most valuable assets.

• About the role
• SambaNova is seeking a Principal Engineer to own kernel-level drivers and low-level software for high-speed IO, memory, and networking subsystems within the DataScale® platform and RDU architecture. This role is central to delivering reliable, high-performance AI systems at scale. This is a hands-on Linux kernel and device driver role; it is not an application or platform software role.

You will lead software bring-up of new silicon, deliver production drivers across the IO, memory, and network data paths, and debug complex issues spanning kernel, firmware, and hardware. This role suits an engineer with deep kernel and driver expertise and strong hardware fluency, who can operate in ambiguity and execute with high ownership.

Responsibilities

Own kernel-space drivers for high-speed IO, memory, and networking subsystems, from architecture through production release

Own the RDMA and network data path, including queue-pair management, congestion control, QoS, and packet classification

Lead software enablement for platform bring-up across new silicon and system configurations

Drive issues to root cause across kernel, firmware, and hardware layers with hardware, firmware, and validation teams

Own PHY and link bring-up in coordination with hardware teams, working from specifications and register documentation

Build tools, test scripts, and frameworks for device and NIC verification, performance analysis, and manufacturing test

Identify and resolve bottlenecks across driver, network stack, and system layers at data center scale

Set code quality standards through design and code review, and mentor engineers on the team

Required Qualifications

MS in Computer Science, Electrical Engineering, or a related field

7+ years of experience in kernel or low-level system software development

Deep expertise in Linux systems programming and kernel driver development

Strong knowledge of Linux kernel networking, including network driver development and the RDMA protocol

Strong C/C++ programming and debugging skills, with scripting in Python or shell

Experience with two or more high-speed IO or interconnect technologies such as PCIe, Ethernet, or CXL

Proven ability to lead hardware-software co-debug from first silicon to production

Ability to read and distill hardware specifications and register-level documentation

Clear and effective communicator with a proactive, collaborative approach to problem-solving

Preferred Qualifications

Hands-on RDMA data-path or driver implementation experience

Experience with virtual switching and data center networking at scale

Experience writing test scripts to verify NIC behavior

Firmware development experience

Exposure to pre-silicon validation using FPGA or emulation platforms

Background in high-performance computing or accelerator-based systems
