Senior Signal Integrity and Power Integrity Engineer

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.

The Signal Integrity/Power Integrity (SIPI) team is a centralized SIPI resource within Waymo. The team is responsible for ensuring that all electrical designs meet functional SI and PI performance metrics before they progress to production. The team covers a variety of designs including silicon package, PCB, connector and cabling systems, which serve as core parts of computing modules and sensor suites in our autonomous driving systems.

Acting as a critical bridge between schematics and layout, the team rigorously evaluates circuit designs, layout and integration constraints, along with hardware prototypes through structured simulation plans, data-driven analysis, and industry-standard validation methodologies.

You will:

• Lead SI and PI design across assigned hardware projects, including lidar, camera, compute modules, and custom silicons
• Deliver end-to-end results from pre-layout feasibility study, post-layout simulation to post-fab correlations
• Define SI and PI acceptance criteria and partner with bench validation teams to root-cause and resolve SI and PI related issues
• Review and direct vendor design and simulation workflows where applicable
• Identify design risks and drive cross-functional solutions in collaboration with EE, PCB layout, Firmware and Mechanical teams

You have:

• Masters Degree in Electrical Engineering with 3+ years relevant working experience
• Be able to perform SI and PI simulation softwares such as Ansys HFSS, SIwave, PowerSI, ADS, HSPICE. Familiar with working with IBIS AMI models
• Understand PI fundamentals. Be able to perform power-noise-aware SI analysis
• Familiar with lab equipment such as VNA and TDR, demonstrated experience with simulation-to-measurement correlation and solving real-world SIPI problems.
• Excellent communication skills with experience to collaborate with internal and external teams
• Depending on the project, be able to work with overseas team (east Asian time zone)

We prefer:

• Ph.D. in Electrical Engineering or relevant field with 3+ years relevant working experience
• Familiar with substrate and PCB design rules, stackups, materials selection and HDI process. Has experience with the package-board co-design process
• Deep understanding in one or more of the following areas: SERDES, LPDDRx, or >200A PDN design
• Experience in root-cause analysis and debugging of real-world SI and PI hardware issues
• Experience with DoE simulation for high-volume production intended designs
