Summary
Senior hardware engineer at Ayar Labs in Hsinchu, Taiwan, designing and building production and characterization test hardware — probe cards, load boards, and test circuitry — for the company's TeraPHY and SuperNOVA optical interconnect devices, working with ATE systems, foundries, OSATs, and vendors.
Responsibilities:
- Support HW projects requested by both San Jose and Taiwan Test teams.
- Design and develop Probe Cards and Load Boards for Production Test based on inputs from Design, Product, and Test teams.
- Design and develop small circuit boards and related hardware for Characterization Test based on inputs from Product and Test teams.
- Work with vendors to source high-quality fibers, fiber arrays, optical instruments, probe cards, load boards, circuitry, and other Test collaterals to support characterization and screening of TeraPHY and SuperNOVA devices.
- Drive vendor timelines to enable on-time delivery of Test collaterals.
- Support bring-up and debug activities related to hardware and collaterals in Lab, Foundry and OSAT environments.
- Maintain and support test equipment, including installing hardware and software.
- Provide hardware technical support to both internal teams and external customers.
- Provide lab support for Characterization Test hardware (rework, soldering, and troubleshooting).
Required Qualifications:
- BS + 2 years of experience in Electrical Engineering, Computer Engineering, or related field.
- Experience designing high-density multi-layer printed circuit boards (PCBs) and multi-layer organic (MLO) probe cards.
