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 Test Development Engineer is the main focal point in the development of a test solution, capable of deciding the technical direction and strategy of the test design and its implementation. He is responsible for developing hardware and software solutions for SiTime’s precision timing devices. From the initial product development kickoff through end-of-life, the ATE Test Development Engineer defines ATE test hardware and software and supports the launch of new products into high-volume production.

This includes board-level hardware design, algorithm development, software implementation, and validation on both custom and standard automated test equipment (ATE) platforms.
