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: .

As a Senior Test Technician, you will support the setup, validation, and sustaining of production test solutions for Automated Test Equipment (ATE) and oven-based trimming/calibration systems.

Working closely with test engineers, manufacturing, equipment, OSAT partners, and cross‑functional teams, you will perform hardware setup and troubleshooting, execute qualification and correlation activities, and drive rapid issue resolution and continuous improvement across production lines. It is not necessary to meet all job requirements to be a qualified candidate for the position.

• Set up, operate, and maintain Eagle Test Systems (ETS
