About this role

PCB Rework Technician San Jose, CA, United States About Etched Etched is building AI chips that are hard-coded for individual model architectures. Our first product (Sohu) only supports transformers, but has an order of magnitude more throughput and lower latency than a B200. With Etched ASICs, you can build products that would be impossible with GPUs, like real-time video generation models and extremely deep & parallel chain-of-thought reasoning agents. Job Summary We are seeking a highly skilled PCB Rework Technician with advanced capabilities in large BGA rework (including components >70mm) and complex board-level repairs involving fine-pitch components down to 0402. This role is critical to supporting engineering, validation, and bring-up efforts by performing high-reliability rework on advanced PCBs, including those supporting custom ASICs. Key responsibilities - Perform precision rework and re-balling of very-large BGAs (custom ASIC packages > 70 mm) with high first-pass yield. - Operate large-format BGA rework systems, ensuring exact alignment, controlled thermal profiles, and clean re-flow on high-pin-count ICs. - Rework SMT and through-hole components down to 0402 packages, maintaining exceptional workmanship and consistency across boards. - Read and interpret ECNs, schematics, layout files, and BOMs to execute component swaps and design modifications accurately. - Execute advanced board-level repairs: trace cuts, jumper-wire additions, micro-soldering, and circuit rerouting. - Inspect reworked assemblies with X-ray or AOI equipment to verify solder-joint integrity, alignment, and overall quality. - Maintain detailed rework documentation and clearly communicate findings or improvement ideas to engineers. - Collaborate closely with hardware, validation, and bring-up teams
