Principal Post-Silicon Validation Engineer

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 Principal Post-Silicon Validation Engineer will provide technical leadership for the validation, characterization, and productization of SiTime’s MEMS-based precision timing products. In this highly visible role, you will define validation strategies, measurement methodologies, release criteria, and risk assessment approaches from first silicon through production release. Working across design, product engineering, test engineering, quality, reliability, and operations teams, you will drive system-level understanding, resolve complex technical challenges, and influence next-generation product and validation architectures.

We are seeking a hands-on technical leader with deep expertise in semiconductor validation, characterization, debugging, and data analysis, combined with the ability to lead cross-functional initiatives and mentor engineers across the organization. Candidates do not need to meet every listed requirement to be considered for the position.

Responsibilities:

Qualifications & Requirements

• MS or PhD in Electrical Engineering, Mechanical Engineering, Physics, or a related discipline. Exceptional candidates with other technical backgrounds will be considered. 
• 10+ years of experience in post-silicon validation, characterization, and productization of semiconductor, MEMS, analog, mixed-signal, or sensor-based products.
• Proven track record of leading complex cross-functional engineering projects from concept through production release.
• Extensive experience defining validation strategies, test methodologies, characterization plans, risk assessments, and production release criteria.
• Strong, fundamental knowledge of analog and mixed-signal circuits, semiconductor devices, and measurement techniques.
• Hands-on experience with laboratory instrumentation, automated test systems, and hardware debug. Experience with timing metrology systems is highly desirable.
• Experience developing automated measurement, data-processing, and analysis solutions using Python, MATLAB, or similar programming environments.
• Strong statistical analysis skills with experience interpreting large characterization datasets and making data-driven engineering decisions.
• Experience leading root-cause investigations and resolving complex silicon, package, test, and system-level issues.
• Strong communication and leadership skills with the ability to influence technical decisions across organizational boundaries.
• Demonstrated ability to mentor engineers, influence technical decisions, and provide technical leadership in a highly collaborative environment.

Preferred Qualifications

• Experience with precision timing, oscillators, clocks, resonators, MEMS devices, or frequency-control products.
• Knowledge of phase noise, jitter, Allan deviation, frequency stability, and precision timing measurement techniques.
• Experience transferring characterization methodologies, screening algorithms, and test limits into high-volume manufacturing environments.
• Experience designing PCB-based validation platforms, embedded firmware, and automated test infrastructure.
• Experience influencing product architecture, technology roadmaps, engineering capabilities, and long-term organizational growth initiatives.

Compensation Range:

At SiTime, we believe great work deserves great rewards. We offer a comprehensive and highly competitive compensation package designed to attract top talent.
