Accelerator Software Engineer

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.

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:

• 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.

• 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.

Etched believes in the Bitter Lesson. We are the first inference-focused frontier AI system, betting early on transformer and transformer-like architectures and on increasing model sizes. Our addressable market is the entirety of inference, unlike many of our competitors.

We are a fully in-person team in San Jose (Santana Row), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both as needed.
