Job summary

Etched in San Jose is seeking an engineer to own accelerator software, spanning ASIC firmware, microcontroller firmware, and host kernel interfaces. You will connect the chip to the host, enabling low-latency inference workflows.

Effective candidates will have strong firmware expertise, embedded systems knowledge, and hands-on experience with Linux drivers and PCIe, contributing across disciplines as the team grows.

Qualifications

• 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 IO technologies like ARM, PCIe, DMA, HBM, DRAM, Ethernet, UART.

Responsibilities

• Own the accelerator software that makes our chips usable across ASIC, MCU, and host interfaces.
• Collaborate on ASIC architecture, on-device inference instruction execution, bootloaders, IO drivers, and on-chip software.
• Develop platform software for power sequencing, telemetry, and firmware updates.
• Build and maintain host-side Linux kernel drivers and memory management for high-throughput interfaces.
• Grow across domains and contribute across firmware, platform, and host software as the team expands.

Job description

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. Involves close collaboration with the hardware team in the schematic and bring-up phases.

• Host-side Kernel and Drivers - the host software that presents our chips as a device the rest of the stack can program against. Linux kernel drivers, PCIe-visible memory management, high-throughput low-latency ring buffer command queues, and SRIOV VF device management.

You may be a good fit if you have

• 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.

Strong candidates may also have experience with (Nice-to-have qualifications)

• 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

How we’re different

Etched believes in Bitter Lesson. We are the first inference-focused frontier AI system. 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 and work across disciplines as needed.
