Senior Product Test 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.

As the Senior Product Test Engineer at Etched, you will own the electrical debug and engineering side of our AI systems, ensuring seamless product introduction from NPI through high-volume ramp. You will collaborate with hardware, ASIC, diagnostics, test, and reliability engineering, as well as partner closely with EE designers and EE validation engineers to drive diagnosability, manufacturing predictability, yield process and material improvements, and product reliability.

This role focuses on PCBA and L10 Server diagnosability and efficiency of repair, and sustaining improvements to ensure our AI hardware meets the highest standards of quality and reliability.

  Lead PCBA test fixture design and support factory implementation.

• Bachelor’s or Master’s degree in Electrical Engineering or a related field.

• 5+ years of experience in manufacturing, product, or electrical engineering.

• Strong knowledge of system hardware architectures and PCB fabrication/assembly processes.

• Strong understanding of electronics circuits, schematics, and PCB Layouts.

• Experience with DFX/DFM, yield assessment, and board-level debug.

• Hands-on experience with PCB CAD/CAE tools (e.g., Allegro, Valor) and understanding of design-to-build flows.

• Proven ability to work across NPI and sustaining environments, from proto bring-up to ramp.

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 and work across disciplines as needed.
