About Asad Khan
I’m a Systems Software Engineer with 5 years of experience developing Linux kernel device drivers, embedded software, and firmware for high-performance computing (HPC) systems and Smart NICs. I love to work at the intersection of hardware and software, and I get genuinely excited about writing code that directly controls and interacts with hardware.My work has contributed to 6 of the 10 fastest supercomputers in the world, where I’ve solved challenging problems in networking, media subsystems, ASIC bring-up, and hardware offloads.I’m passionate about low-level software that pushes hardware performance to its limits, and I enjoy solving challenging integration problems that bridge silicon, firmware, and the OS kernel.Core Skills: Linux kernel • Embedded software • Firmware • Device driver development • HPC systems • Smart NIC • Ethernet drivers • RDMA • Networking protocol offload • ASIC bring-up • x86 • ARM • Hardware-software integration
Experience
Systems Software Engineer
Feb 2023 — Present · Austin, TX, US
Contributed to the development of 6 of the 10 fastest supercomputers in the world.* Developed and maintained Slingshot high-performance Ethernet switch and NIC device drivers in the Linux kernel for HPE Cray supercomputers and HPC clusters, ensuring compatibility across x86, ARM, and heterogeneous architectures.* Owned the design and implementation of the complete media subsystem for the Ethernet link driver in the Linux kernel, covering hot-plug cable detection, hardware interrupt handling, media type validation, power sequencing, and dynamic speed negotiation for HPC systems.* Enhanced network resilience in supercomputing clusters by engineering the Auto Lane Degrade fault-recovery protocol, reducing downtime and sustaining performance under hardware faults.* Contributed to post-silicon ASIC bring-up by identifying and resolving hardware-driver integration bugs, optimizing register-level configurations, ensuring stable performance.* Collaborated on firmware and Linux kernel modules for media power-up sequences and LED control for hardware status indication.* Delivered seamless user-space integration by implementing sysfs interfaces for all media attributes, enabling comprehensive monitoring and configuration tools.* Built inter-driver communication systems for link drivers, switch drivers, and NIC drivers, improving driver coordination and data path stability.
