Sr. Engineer, Test Engineering

SiTime Corporation•Santa Clara, CA

About The Position

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 . As a Test Development Engineer, you will contribute to the development, validation, and deployment of production test solutions for Automated Test Equipment (ATE) and oven-based trimming/calibration systems. Working closely with product, design, manufacturing, and quality teams, you will support new product introduction (NPI), test program development, hardware bring-up, and data analytics initiatives to ensure robust and scalable manufacturing test solutions. This position offers an excellent opportunity for early-career engineers to gain hands-on experience in semiconductor test development, automation, system integration, and data-driven yield improvement. Candidates with strong technical fundamentals, programming aptitude, and a passion for problem-solving are encouraged to apply. It is not necessary to meet all job requirements to be a qualified candidate for the position.
