You'll Collaborate With

Firmware, silicon, runtime, datacenter software and architects teams to deliver a robust kernel foundation that integrates seamlessly with modern datacenter environments and AI workloads.

What You’ll Own

• PCIe Foundation: Design and implement robust PCIe kernel drivers for AI accelerator enumeration, configuration, and management that form the critical host-device communication backbone.
• High-Speed Data Movement: Develop DMA engines and memory management systems that deliver zero-copy, high-throughput data movement between host and accelerator for massive AI workloads.
• Firmware Bridge: Build interrupt handling (MSI/MSI-X) and mailbox communication protocols that create seamless coordination between kernel space and our firmware stack.
• System Observability: Create comprehensive sysfs/debugfs interfaces for device configuration, telemetry, and diagnostics that give operators deep visibility into accelerator operations.
• Multi-Die Orchestration: Support multi-die topologies through device discovery, link management, and topology coordination that scales from single-card to cluster deployments.
• Power & Thermal Intelligence: Develop power management and thermal control integration with Linux PM frameworks that optimize performance while maintaining reliability.
• Reliability Engineering: Contribute to device health monitoring, error handling (RAS), and recovery mechanisms that deliver the 99.99% uptime datacenter customers require.
• Performance Optimization: Optimize kernel-space performance for AI workloads, focusing on latency, throughput, and scalability that directly impacts model training and inference speed.
• Time Synchronization: Support PTP/PHC time synchronization for distributed training and inference that ensures coordination across multi-node AI clusters.
• Runtime Partnership: Collaborate with userspace runtime teams on kernel-userspace interfaces and APIs that enable efficient scheduling and resource sharing.
• Future-Ready Architecture: Lay the groundwork for device virtualization and multi-tenant isolation, ensuring our platform can evolve with customer needs.

Minimum Qualifications
