Sr. MEMS Production Test Engineer - Santa Clara, CA, United States
$138,800 USD yearly
Originally posted 12 December 2025 by the employer — open 271 days.
Support MEMS-based Precision Timing wafer-level testing.
About the role
This role involves ensuring smooth, efficient, and high-quality MEMS wafer-level testing and supporting day-to-day production activities. The engineer will design and execute data-driven experiments to improve yield, enhance test coverage, and reduce cycle time for MEMS programmable solutions.
What you'll do
- Support daily production test operations by monitoring test performance and troubleshooting equipment and hardware issues.
- Manage probers, probe cards, test hardware, and test programs, including qualification, maintenance, and failure analysis.
- Coordinate with vendors to resolve equipment issues, implement test improvements, and manage logistics.
- Maintain, optimize, and validate test programs; collaborate with engineering teams to improve test coverage and yield.
- Design and run DOE experiments to improve yield, reduce cycle time, and support continuous improvement.
- Maintain and enhance MES workflows to ensure accurate, efficient, and reliable production execution.
- Develop and manage recipes for defect detection using automated optical inspection (AOI) tools.
What you'll need
- BS, MS, or PhD in Electrical Engineering, Mechanical Engineering, Physics, Materials Science, or a related technical field.
- 5+ years of experience in semiconductor, MEMS, or high-volume manufacturing test environments.
- Hands-on experience supporting production test operations, including ATE systems, probers, and wafer-level test hardware.
- Experience debugging probe cards, including both cantilever and vertical pin architectures.
- Proven proficiency in developing and automating test programs using C#, LabVIEW, or Python.
- Strong knowledge of Statistical Process Control (SPC), yield analysis, and wafer probe/test methodologies.
Nice to have
- Familiarity with MEMS fabrication processes.
- Experience with wafer sort.
