Manufacturing Test Engineer (Taiwan)

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. Taiwan is where our products get built. Our Manufacturing Test Engineering team sits closest to the line — you will be the engineer the factory calls when a board, a module, or a rack does not pass. Job Summary As a Product Test Engineer on the Manufacturing Test Engineering team in Taiwan, you will own the electrical debug and failure analysis side of our AI systems at our contract manufacturing partners, taking products from NPI bring-up through high-volume ramp. You will work hands-on at the factory alongside CM/ODM engineers, and partner with our hardware, ASIC, diagnostics, test, and reliability teams in Taiwan and San Jose to drive diagnosability, manufacturing predictability, yield and material improvements, and product reliability. This role focuses on PCBA and L10/L11 server diagnosability and efficiency of repair, plus the sustaining improvements that keep our AI hardware at the highest standards of quality and reliability. Builds, bring-ups, and yield escalations require a hands-on approach and flexibility to adapt to critical project timelines as we move products from NPI through high-volume ramp. Key Responsibilities - Troubleshooting & repair: Diagnose and repair electronic assemblies (PCBA) down to the component level; isolate faults across module, L10, and L11 levels. - Factory ownership: Work directly on-site with Contract Manufacturers (CMs) and ODMs in Taiwan to close capability gaps, improve yield, and qualify new components. - Ad-hoc bring-up: Support new-product and new-station bring-up on short notice — pr
