Zoox is an autonomous mobility company that’s created a purpose-built robotaxi to give the world a better way to ride.
The Role
Lead signal and power integrity architecture for advanced robotaxi electronics and high-density PCBs. Define SI/PI constraints, routing strategies, simulation methodologies, and sign-off processes for PCIe, Ethernet, MIPI, GMSL, LPDDR, and A2B interfaces. Perform PDN analysis, lab characterization, root-cause investigations, and simulation-to-test correlation. Guide cross-functional hardware, silicon, layout, and mechanical teams while mentoring engineers and influencing technical strategy.
Summary Generated by Built In
We are seeking a highly skilled and visionary Staff Signal and Power Integrity (SI/PI) Engineer to join our advanced hardware engineering team. In this role, you will be the definitive technical expert responsible for ensuring the signal quality, timing, and power delivery robustness of our most complex, next-generation robotaxi electronic systems. As a technical pillar within the organization, you will define overarching SI/PI architectures, establish company-wide simulation methodologies, guide electrical design and layout teams, and own the end-to-end sign-off for cutting-edge high-speed interfaces.
In This Role, You Will
- Lead the SI/PI architecture and define constraints for next-generation, high-complexity, high-density printed circuit boards (PCBs) and overall system design.
- Collaborate at an architectural level with hardware design, silicon vendors, PCB layout, and mechanical engineering teams to define layer stack-ups, routing strategies, component placement, and power delivery architectures.
- Analyze, optimize, and sign off on advanced high-speed serial links (PCIe, Ethernet, MIPI, GMSL) and memory interfaces (LPDDR).
- Provide expert-level design guidance and validation for automotive-specific communication and audio protocols (A2B).
- Architect and conduct comprehensive Power Delivery Network (PDN) analysis, including DC IR drop, AC impedance modeling, and transient response analysis to ensure stable power delivery across complex multi-board systems.
- Drive the development of advanced SI/PI routing rules, simulation methodologies, automation scripts, and sign-off processes for the hardware engineering department.
- Tackle the most complex, unprecedented signal and power integrity challenges, performing hands-on root-cause analysis, lab measurements, and correlating simulation models with real-world testing.
- Act as a technical mentor and subject matter expert, elevating the SI/PI capabilities of the entire hardware organization and guiding junior to senior engineers.
Qualifications
- Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, Computer Engineering, Physics, or a closely related technical field.
- 10+ years of proven industry experience in signal and power integrity analysis for complex high-speed digital designs.
- Extensive, proven track record designing, simulating, and troubleshooting high-speed interfaces, specifically PCIe, multi-gigabit Ethernet, MIPI (CSI/DSI), and GMSL, through multiple successful product lifecycles.
- Deep expertise in memory interface design and simulation, with a strong focus on advanced LPDDR technologies.
- Familiarity with automotive audio and sensor bus protocols, such as A2B.
- Advanced proficiency with industry-standard 2D/3D electromagnetic extraction and SI/PI simulation tools (e.g., Ansys HFSS/SIwave, Keysight ADS, Cadence Sigrity, or Siemens EDA/HyperLynx).
- Mastery of electromagnetics, transmission line theory, cross-talk, jitter, and advanced PDN design principles.
- Expert-level hands-on experience with high-speed lab characterization equipment, including Vector Network Analyzers (VNAs), Time-Domain Reflectometers (TDRs), and high-bandwidth oscilloscopes.
Bonus Qualifications
- Direct experience in the automotive industry, particularly developing hardware for advanced driver-assistance systems (ADAS) or autonomous vehicles.
- Deep understanding of automotive reliability standards, compliance requirements, and designing for harsh environmental operating conditions.
- Extensive experience with high-layer-count HDI (High-Density Interconnect) PCB design, advanced packaging, and pushing the boundaries of modern fabrication capabilities.
- Proven ability to influence technical strategy, drive cross-functional alignment, and clearly communicate complex technical trade-offs to executive and non-SI/PI stakeholders.
