About Si Time

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: .

Timing Products Division (TPD) is seeking a Senior Staff Product Engineer to lead the development and production ramp of state-of-the‑art mixed‑signal timing products. This is a unique opportunity to provide end-to‑end product engineering leadership, from product conception and NPI through qualification, production release, yield improvement, and end‑of‑life.

The Senior Staff Product Engineer will work closely with cross‑functional teams including Design, Test, Quality, Operations, Applications, and external suppliers to ensure products meet datasheet specifications, customer requirements, and applicable JEDEC/AEC quality standards. The role will also lead test strategy, product qualification, BOM management, yield optimization, and resolution of supplier and customer excursions.

• Provide end‑to‑end product engineering ownership from product concept through end‑of‑life, with a focus on delivering high‑quality products to customers.
• Lead the definition and execution of ATE test, product qualification, and manufacturing strategies.
• Drive new product introduction (NPI) and product release into manufacturing while ensuring compliance with stringent Tier 1 customer requirements.
• Develop and maintain datasheets, automotive compliance documentation, and product‑related technical reports.
• Own product Bill of Materials (BOM) release and maintenance throughout the product lifecycle.
• Lead supplier and customer excursion management, including root‑cause analysis, corrective actions, and cross‑functional resolution.
• Drive yield improvement through statistical analysis, data mining, root‑cause investigation, and implementation of corrective actions.
• Monitor key product and manufacturing metrics, generate regular yield/performance reports, and communicate findings and improvement plans to product engineering teams and leadership.
• Drive achievement of product engineering KPIs, including NPI execution and velocity, gross margin improvement, product quality, and failure‑analysis cycle time.
• Optimize PAT, SYL, SBL, SPC limits, and disposition strategies to protect product quality while minimizing unnecessary manufacturing waste.
• Partner with design and test engineering teams to optimize product test coverage, DFT, manufacturability, and production robustness.
• Provide technical leadership and mentorship to product engineering team members and influence cross‑functional technical decisions.

• 10+ years of experience in semiconductor product engineering.
• Strong understanding of analog and mixed‑signal circuits, common circuit building blocks, semiconductor device physics, test methodologies, and Design‑for‑Test (DFT) concepts.
• Strong analog circuit background is required; experience with semiconductor timing products such as PLLs and clock generators is highly desirable.
• Experience with ATE tester platforms…
