MEMS Product/Test Engineer

MEMS Product/Test Engineer


Company Profile

Founded in 1991, Silicon Microstructures, Inc. (SMI) is a world leader in the design and manufacture of Micro Electro-Mechanical Systems (“MEMS”) that lie at the heart of the advanced sensing market, enabling devices in the medical, industrial, automotive and consumer sectors.

The company has established itself as a premier provider of MEMS-based pressure sensors for a range of markets, supplying advanced high and low-pressure sensor products that meet the stringent requirements for industry and consumer safety. Silicon Microstructures’ design, production and quality control processes have enabled it to develop both the smallest and smartest pressure sensors available today. SMI offers a wide range of pressure sensors, including uncompensated sensors, temperature compensated and calibrated products as well as sensor systems consisting of an ASIC paired with a sensor die in a custom package.


Summary of Position

An essential job function of the MEMS product/test engineer is the implementation and maintenance of systems to monitor, organize and report production data of assembled MEMS pressure sensor devices at the SMI production and test facility in Milpitas. These MEMS pressure sensor devices consist mainly of an SMI pressure sensor die and a signal-conditioning ASIC in an SMI custom package. He/she will be responsible for supporting production testing of packaged pressure sensor devices by improving and maintaining the test programs and tester hardware of the current production processes. The engineer plays an active role in quality improvement in the framework of SMI’s IATF16949 quality management system.
