Job Description
Zoox seeks a Staff Signal Integrity and Power Integrity Engineer to direct signal quality, timing, and power delivery for advanced robotaxi electronic systems. In this position, the specialist will function as a central technical authority, setting department simulation practices, formulating overarching SI/PI architectures, and managing final sign-off for sophisticated high-speed interfaces.
This opportunity fits an experienced hardware professional capable of addressing unprecedented technical hurdles and steering multi-functional alignment across silicon vendors, layout specialists, and mechanical teams. Zoox develops next-generation autonomous vehicle hardware, requiring robust solutions that adhere to strict reliability standards.
The role involves hands-on laboratory measurements, root-cause investigations, and mentorship for engineering colleagues. Candidates will tackle high-density circuit board layouts, power delivery network simulations, and advanced serial link optimizations. Equal emphasis is placed on architectural planning and practical laboratory characterization using high-bandwidth measurement equipment.
Responsibilities
- Determine SI/PI architecture and establish constraints for high-density printed circuit boards and overall system designs
- Partner with hardware design, silicon vendors, PCB layout, and mechanical engineering groups to outline stack-ups and routing strategies
- Evaluate, refine, and sign off on high-speed serial links including PCIe, Ethernet, MIPI, and GMSL, alongside LPDDR memory interfaces
- Deliver design guidance and validation for automotive audio and communication protocols such as A2B
- Design and execute Power Delivery Network analyses covering DC IR drop, AC impedance modeling, and transient response
- Build department routing guidelines, simulation methodologies, automation scripts, and sign-off procedures
- Perform hands-on laboratory measurements, root-cause debugging, and correlation of simulation models with physical testing
- Mentor junior and senior engineers while acting as a subject matter expert for the hardware organization
Requirements
- Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, Computer Engineering, Physics, or a closely related field
- Over ten years of industry background in signal and power integrity analysis for advanced high-speed digital designs
- Track record of designing, simulating, and troubleshooting high-speed interfaces like PCIe, multi-gigabit Ethernet, MIPI, and GMSL through multiple product lifecycles
- Expertise in memory interface design and simulation centered on LPDDR technologies
- Familiarity with automotive sensor and audio bus protocols such as A2B
- Proficiency with electromagnetic extraction and simulation platforms including Ansys HFSS/SIwave, Keysight ADS, Cadence Sigrity, or Siemens EDA/HyperLynx
- Mastery of transmission line theory, electromagnetics, cross-talk, jitter, and PDN design principles
- Hands-on expertise utilizing lab characterization gear such as VNAs, TDRs, and high-bandwidth oscilloscopes
Qualifications
- Prior background in the automotive sector creating hardware for autonomous vehicles or advanced driver-assistance systems
- Knowledge of automotive reliability standards, compliance needs, and harsh operational environment design
- Experience working with high-layer-count HDI PCB design, advanced packaging, and modern fabrication capabilities
- Ability to steer technical strategy and communicate complex trade-offs to executive stakeholders
