Kernel Driver Software Engineer
Etched, San Jose
What you will do
- Design, develop, and maintain kernel-mode drivers ensuring high reliability, informative debug, and optimal performance.
- Analyze and optimize driver performance for demanding AI workloads, focusing on minimizing latency and maximizing throughput.
- Collaborate closely with hardware engineers throughout the ASIC design process..
- Implement driver support for device virtualization technologies, including SR-IOV, VFIO, and para-virtualization.
- Implement efficient memory management strategies considering kernel memory mapping, page tables configuration, NUMA awareness for device data caching, and IOMMU configuration.
- Build kernel drivers fundamentally designed to support and maintain security across host processes, physical memory spaces, and device attestation.
- Diagnose and resolve complex driver-related issues, using common kernel debugging tools and techniques (ftrace, dmesg, etc.) to identify and fix bugs.
- Design and implement synchronization mechanisms to handle concurrent access to multiple accelerators.
- Develop and execute comprehensive test plans to validate driver functionality, stability, and performance in manufacturing and in general production environments.
