Embedded Software Engineer

This role owns the accelerator software that makes our chips usable. You'll work across the layers that bring the chip to life and connect it to the host: the firmware that powers it on, the on-die software that initializes and manages it, and the kernel-level interface that exposes it to the rest of the inference stack. The work spans three tightly-coupled domains; ASIC firmware, microcontroller firmware, and host-side kernel and drivers. We hire engineers who are deep in one area and curious about the others.

Responsibilities

Owns the accelerator software that makes our chips usable; Works across firmware, on-die software, and kernel-level interface; Specializes in one of ASIC Software, Platform Software, or Host-side Kernel and Drivers; Collaborates on ASIC architecture, on-device inference instruction execution, CPU initialization, bootloaders, IO drivers, thermal and power management, DMA data transfer, on-chip application software, and validation; Develops microcontroller architecture and software for power sequencing, telemetry, and firmware update; Develops Linux kernel drivers, PCIe-visible memory management, high-throughput low-latency ring buffer command queues, and SRIOV VF device management

Requirements

Bachelor's degree or equivalent practical experience; Strong software development fundamentals, including data structures and algorithms; Experience shipping and testing software on products that have gone to production; Depth in firmware design, implementation, and debugging; Familiarity with embedded architectures and the IO technologies that live at the silicon-to-host boundary — ARM, PCIe, DMA, HBM, DRAM, Ethernet, UART — and with systems concepts like scalability, fault tolerance, and consistency

Nice to have

Master's degree in Computer Science or equivalent technical experience; Hardware bring-up on a new chip or board, for the first time ever; Solving ambiguous, under-specified problems where the requirements emerge alongside the solution; Experience using low-level computer architecture details, like caching or AXI fabrics, to enable software to make decisions at the nanosecond-level; Strong communication, particularly when collaborating directly with engineers and across discipline boundaries

Benefits

Medical, dental, and vision packages with generous premium coverage; $500 per month credit for waiving medical benefits; Housing subsidy of $2k per month for those living within walking distance of the office; Relocation support for those moving to San Jose (Santana Row); Various wellness benefits covering fitness, mental health, and more; Daily lunch + dinner in our office; Unlimited compute budget subject to ROI justification
