Select, configure, and maintain specialized test instrumentation, including probe stations, precision source-measure units (SMUs), oscilloscopes, and custom MEMS test fixtures. Perform hands-on testing in both cleanroom and laboratory environments, ensuring proper handling of sensitive MEMS devices and adherence to ESD and contamination-control procedures. Analyze and interpret test data to evaluate device performance, identify trends, and diagnose issues at both the device and system level. Collaborate closely with design, process, and product engineers to troubleshoot, optimize test coverage, and improve product yield and reliability. Thoroughly document all test plans, configurations, and results to ensure full traceability and enable continuous improvement in test methods and equipment. Drive improvements in throughput, automation, and measurement accuracy across the MEMS test process flow. Ensure all activities comply with quality standards, customer requirements, and relevant industry regulations. We are looking for someone who has A Masters degree or Ph.D. in Engineering, preferably in Electrical Engineering, Engineering Physics, or a related field. At least 3 years of experience in electrical measurements, device characterization, or production tests – ideally including MEMS or semiconductor tests within an industrial environment or academia. Experience in LabVIEW programming for test automation, instrument control, and data acquisition. Proficiency in Python and familiarity with SQL databases for data analysis, visualization and structured data management. Hands-on experience with a wide range of test equipment, such as source-measure units (SMUs), parametric analyzers, probe stations, oscilloscopes, spectrum analyzers, and other specialized tools used in MEMS testing. Experience in cleanroom or controlled laboratory environments. Strong analytical mindset and problem-solving skills, with the ability to troubleshoot complex device- and system-level issues. Basic knowledge or experience in 3D CAD modeling and prototype manufacturing methods (e.g., 3D printing, CNC machining) for test fixture design and development.
