Accelerator Software Engineer

About Etched Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history. Job Summary 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. This role spans across three work areas. You would specialize in one and contribute across the others as the team grows: - ASIC Software— Collaboration 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. The code that runs on the die itself on its various embedded CPUs. - Platform Software — microcontroller architecture and software for power sequencing, telemetry, and firmware update, and the foundational work that takes the chip from powered off to responsive.
