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 .

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 such as Teradyne J750 or Advantest 93K.
• Experience developing and executing semiconductor product test plans and manufacturing test strategies.
• Experience developing qualification hardware and/or software.
• Experience with common laboratory test equipment, including oscilloscopes, multimeters, DC power supplies, and related instrumentation.
• Experience with product qualification and familiarity with JEDEC and AEC qualification standards and stress-test conditions.
• Experience with yield management and statistical analysis tools such as PDF Exensio and JMP.
• Demonstrated ability to use statistical analysis and data-driven methods to identify root causes and drive yield improvement.
• Demonstrated experience managing supplier excursions and customer escalations through structured problem solving and cross-functional collaboration.
• Bachelor's degree in Electrical Engineering, Electronics Engineering, or a related field required; Master's or Ph.D. preferred.
• English proficiency is required, including the ability to effectively communicate, collaborate, and perform job responsibilities in a professional business environment.

• Experience with mixed-signal timing products, including PLLs, clock generators, or related devices.
• Bench characterization experience for analog and mixed-signal semiconductor products.
• Experience with automotive semiconductor products and customer-specific quality requirements.
• Experience with PAT, SYL, SBL, SPC, and statistical disposition optimization.

• Strong verbal, written, and technical communication skills.
• Demonstrated technical leadership and ability to influence cross-functional teams.
• Strong analytical and problem-solving skills with a data-driven approach.
• Ability to work effectively with Design, Test, Quality, Operations, suppliers, and customers.
• Strong ownership and accountability for product quality and execution.
• Collaborative team player who thrives in a fast-paced, dynamic environment.
• Ability to mentor and develop less-experienced product engineers.
