Silex is investing strategically in MEMS testing as a core capability to strengthen our position in the market and deliver industry-leading solutions to our customers. As part of this effort, we are expanding our MEMS test infrastructure, methodologies, and expertise. This is a unique opportunity to be part of a forward-looking initiative that will define the next generation of MEMS performance and reliability. 

About the role 

We are looking for a professional with a strong focus on test engineering and hands-on experience with test equipment and measurements, and related software development. 

You will join a growing and collaborative engineering team dedicated to developing advanced test solutions that support the full product lifecycle – from early prototypes to high-volume manufacturing. As a MEMS Test Engineer, you will play a key role in developing, optimizing, and executing test systems – both hardware and software – for a broad range of MEMS products, ensuring performance meets customer specifications and industry standards. You will collaborate cross-functionally within Silex and communicate with both suppliers and customers.   

In this role you will: 

• Design and implement test solutions based on MEMS device specifications, covering electrical, optical, and mechanical performance. 

• Develop and validate test cases and procedures for both manual and automated wafer-level and die-level test systems. 

• Select, configure, and maintain specialized test instrumentation, including probe stations, integration spheres, spectrometers, 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

• M.Sc. or Ph.D. in Engineering, preferably in Electrical Engineering, Engineering Physics, or a related field. 

• At least 5 years of experience in electrical measurements, device characterization, or production tests – ideally including MEMS or semiconductor tests within an industrial environment.  

• Expertise 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, integration spheres, spectrometers, 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. 

What we offer you

• Collaboration with a team of exceptional colleagues who share your passion for technology. 

• Opportunities to work with cutting-edge MEMS technology in a state-of-the-art environment. 

• Being part of a world-leading company that drives innovation and shapes the future of MEMS development. 

• Continuous knowledge sharing with global experts in MEMS process integration and development.
