Systems Engineer, Charging Systems

Foster City, CA /
Vehicle Development – Vehicle Systems Engineering /
Full-time
The Charging Systems Engineering team at Zoox is responsible for the design, development, and production of a highly reliable charging system specifically tailored for charging our SAE L5 autonomous electric vehicle. Our team has an action-biased culture marked by integrity, humility, competence, and passion for the Zoox mission and the systems we design. We are building real products here and are looking for doers to join us.

As a Senior Charging Systems Engineer you will be working on system design, system definition, system analysis, system behaviors, and control mechanization of our SAE L5 EV High Voltage Battery Charging System. This will include coming up with various system requirements based on a first principle system design approach, meeting various SAE, UL, IEC, and ISO standards, and helping various stakeholders both internal and external to the team and company. Work cross-functionally with several amazing engineers to solve complex system problems by breaking them down into more solvable problems. You will work closely with cross-functional teams to understand the root causes of failures, identify mitigation strategies, and incorporate learnings into new designs.

Responsibilities

    • Design and develop charging system architecture and system design based on the first principles approach, functional safety concepts, and detailed system analysis
    • Come up with system behaviors, control mechanization, and interfaces using system diagrams, signal flow diagrams, state machines, etc.
    • Perform system analysis as needed for all aspects of optimization, controls, and performance to guide various components including charging infrastructure
    • Evaluate charging system HV/LV EE components and FW controls using simulation tools and engineering analysis based on the first principles approach to come up with safety protection, deratings, and operating schemas
    • Future charging systems technology evaluation (tech risk assessment, trade studies)
    • Be a subject matter expert and provide guidance to both technical and non-technical teams internal and external to Zoox to build a best-in-class charging system
    • Support system integration, driving DFMEA, fault tree analysis, and come up with, fault diagnostics, fault handling, etc

Qualifications

    • 5+ years of experience working on electric vehicle charging systems that are conceived from the early concept stage to launching into the market and solving field issues
    • Deep technical knowledge of electric vehicle HV battery systems and charging technologies, methodologies, and controls
    • Indepth understanding of various EV DC charging technologies and global charging standards such as SAE J1772, ISO15118, IEC 61851, CHAdeMO, etc, and regulatory requirements including UL, ISO, IEC, etc
    • Experience with automotive communication protocols (CAN, LIN, Flexray, Ethernet, SPI, I2C) and power domains
    • Experience and ability to work safely around high voltage systems up to 500VDC and US power LV service power grid 1-ph and 3-ph
    • Experience using simulation tools such as MATLAB/Simulink, LTSPICE, and programming tools such as Python, C, and C++
    • Ability to work in a fast-paced development environment

Bonus Qualifications

    • Familiarity with industry testing standards (SAE, MIL, UN, UL, GB/T, GTR)
    • Familiarity with 3D design tools
    • High voltage and low voltage PCB design
    • Understanding of Lithium-Ion degradation and failure modes/mechanisms is a huge plus
    • Understanding concepts of EMI/C is a huge plus
