Job description

Zoox is looking for a Senior Signal Integrity and EMC Engineer to ensure the electrical reliability, signal fidelity, and compliance of our complex autonomous vehicle systems. In this role, you will own the end-to-end strategy for vehicle-level signal integrity, RF/wireless performance, and EMC. You will work within a multi-disciplinary engineering team to set rigorous requirements and ensure best practices are implemented from concept to production. You will serve as the domain expert on a variety of high-speed digital and RF design topics that bring our hardware to life safely and reliably.

In this role, you will:

• Lead the development, implementation, and validation of vehicle-level signal integrity, grounding, and shielding strategies. Maintain rigorous technical requirements and EMC specifications applied across all electrical and electronic systems on all vehicle platforms.
• Define and maintain vehicle-level RF performance requirements, establishing specifications for all transmitters, receivers, and antenna systems to mitigate the electromagnetic impacts of physical vehicle installation on wireless communication.
• Perform and/or oversee signal integrity and power integrity (SI/PI) simulations and analysis for critical high-speed interfaces and power distribution networks. Simulate RF performance of all antennas, transmitters, and receivers as installed in a vehicle during the vehicle design phase to drive integration alignment.
• Collaborate with cross-functional design teams to ensure best practices for signal integrity, RF design, and EMC are implemented. Lead design reviews to identify and remediate vulnerabilities early to meet project milestones.
• Develop and execute validation plans for vehicle-level signal integrity, RF/wireless performance, and EMC, including radiated and conducted emissions/immunity. Troubleshoot and resolve complex signal integrity, RF, and EMC issues discovered during design, validation, and in-fleet operation.
• Stay current with emerging automotive technologies, wireless protocols, and high-speed communication standards, actively leveraging industry specifications when establishing internal requirements.

Qualifications

• Bachelor's or Master's of Science in Electrical Engineering with Electronics Design, Electromagnetics, or RF/Wireless-related coursework.
• 10+ years of experience in signal integrity, RF design, and/or EMC validation of electronic components and systems.
• Understanding of CISPR, ISO, SAE, FCC, and UNECE EMC standards and regulations.
• Proficiency utilizing essential test and measurement equipment, such as Network Analyzers, Spectrum Analyzers, and high-bandwidth Oscilloscopes.
• Experience with high-speed digital electronics design, schematic capture, and PCB layout best practices.

Bonus Qualifications

• Hands-on experience with automotive signal integrity and EMC validation and countermeasures.
• Proficiency with industry-standard SI/PI and EM simulation tools
• Familiarity with automotive high-speed protocols and wireless technologies
