About SiTime

SiTime is the Precision Timing company. 

Timing is the heartbeat of all electronics, ensuring performance, resilience and scalability. For decades, quartz devices, non-silicon technology, have kept systems in sync, but they struggle in harsher, more demanding environments. MEMS-based Precision Timing delivers greater accuracy, smaller size and resilience. Today, MEMS timing powers over 400 applications, including high-growth ones in AI datacenters, automated driving, industrial and humanoid robots, wearables and IoT.

Our semiconductor MEMS programmable solutions offer a rich feature set that enables customers to differentiate their products with higher performance, smaller size, lower power, and better reliability. With more than 4 billion devices shipped, SiTime is changing the timing industry. For more information, visit:  www.sitime.com.

Job Summary

The Sr. MEMS Production Test Engineer is responsible for ensuring smooth, efficient, and high-quality MEMS wafer-level testing. This role supports day-to-day production activities including prober management, probe card debug and calibration, vendor coordination, MES configuration, test program qualification, and test instruments troubleshooting. The engineer will also design and execute data-driven experiments (DOE) to improve yield, enhance test coverage, and reduce cycle time. This role collaborates closely with manufacturing, quality, product engineering, test development, process and NPI teams to resolve technical issues and continuously optimize production performance.

• Manage probers, probe cards, test hardware and test programs, including qualification activities, maintenance scheduling, and failure analysis.
• Coordinate with vendors to resolve equipment issues, implement test improvements, and manage spare parts and service logistics.
• Maintain, optimize, and validate test programs; collaborate with design and product engineering teams to improve test coverage and yield.
• Design and run DOE experiments to improve yield, reduce cycle time, and support continuous improvement initiatives.
• 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

Qualifications & Requirements:

• 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; wafer-level experience strongly preferred.
• 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.
• Familiarity with MEMS fabrication processes is a plus.
• Experience with wafer sort is a plus.

Desired Characteristics & Attributes:

• A positive attitude and motivated to learn new skills. 
• Strong written and verbal communication skills required.
• Excellent analytical and problem-solving skills.
• Ability to work well with others in a collaborative fast-paced team environment.
