Sr. Engineer, Analog Mixed-Signal Design

About SiTime

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.
