Role summary

Waymo's Hardware Engineering team is seeking a Senior Signal and Power Integrity (SIPI) Engineer to lead SIPI for products and sub-systems. Responsibilities include project planning, establishing SIPI guidelines, auditing layout, performing simulations, and correlating with measurements. The role requires a Master's degree in Electrical Engineering with 3+ years of experience in system-level SIPI design, modeling, and optimization using software like HFSS and ADS, along with lab equipment familiarity. Preferred qualifications include a Ph.D., expertise in SERDES, SoC PI, or LPDDRx, debugging experience, scripting skills, and knowledge of automotive interfaces. This hybrid role offers a competitive salary range and benefits.

Waymo is an autonomous driving technology company with the mission to be the world's most trusted driver. Since its start as the Google Self-Driving Car Project in 2009, Waymo has focused on building the Waymo Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Waymo Driver powers Waymo’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Waymo Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states.

Hardware Engineering is an innovative and collaborative group of electrical, mechanical, reliability, software and vehicle engineers. We design, build, and perfect the products which are the eyes and ears of Waymo's autonomous driving technology, and integrate those products into vehicle platforms. We're seeking curious and talented teammates to keep us moving in the right direction.
