Job Summary

The Advanced Product Development team develops transformative battery designs and novel product concepts to speed global electric vehicle adoption and energy decarbonization.

Your role will a generalist Electrical Engineer on our team with a focus on BMS and controls electronics. You will develop innovative technologies from concept to on-vehicle integration, enabling high-performance EV packs for internal and customer-driven development programs. The ideal candidate will have deep electrical and electronic design experience both from the circuit level up to the systems level and be familiar with a wide variety of circuit functions from power to control to sensor & signal designs.

We are looking for passionate engineers who share our values. Our team is comprised of various integrated disciplines, including mechanical, structural, thermal, electrical, and software. Therefore, collaboration in group settings, ability to solve system integration challenges, and clear communication are valuable to becoming a successful team member.

You should enjoy working on a small team where you will own substantial and critical parts of the final product. We are working on groundbreaking technologies, so you’ll be energetic, adaptable, and a fast learner who can make quick design judgments with limited information. As a founding member of this group, you will also play a crucial role in growing the team to meet continuously evolving challenges.

Essential Duties and Responsibilities

  • Leads advanced design and develop architectures for functions such as power conversion, signal processing, embedded systems and special function designs related to battery management.

  • Assesses novel technology for application into battery-based products such as wireless cell monitoring, chip-on-cell technology, State of Charge/State of Health (SOX) monitoring solutions & high-accuracy coulomb counting techniques.

  • Creates BMS control and diagnostic algorithms to achieve desired functionality, robustness, and safety.

  • Builds technical subject matter expertise in BMS topics, actively participate in and contribute to technical reviews

  • Conducts trade studies to make the appropriate choice of hardware to support prototyping goals

  • Develops schematics, perform PCB layout, and work with external suppliers for fabrication

  • Identifies areas of risk and work quickly to prototype and mitigate these

  • Brings up new hardware designs and verification of first article hardware prototypes

  • Other duties as assigned

Within 3 months you will:

  • Supports the design and build of a prototype next-generation battery pack

  • Helps develop test setups to iterate on and validate designs

  • Takes ownership of the design, fabrication, and testing of BMS subsystem components

  • Develops internal design tools and capabilities to accelerate future projects

  • Becomes familiar with the ONE team and established products

Within 6 months you will:

  • Develops prototype designs unique to the advanced product development group

  • Takes ownership of advanced pack BMS design

  • Collaborates with other system disciplines to plan and execute overall project delivery

  • Guides high-level design discussions for our current and future product concepts

  • Mentors junior engineers on prototyping and best practices

  • Leads prototyping and fabrication of follow-on product concepts

Education and/or Experience

You should be familiar with all, proficient with many, and expert at some of the following, in no particular order:

  • BS, MS, or PhD in a relevant field (Electrical/Computer Engineering, Mechatronics, Electronics, etc)

  • 3+ years experience in electronics, electrical systems design, controls, or a related field

  • Experience in design of BMS architecture and implementation

  • Experience with embedded controls and software development processes, methods, and tools

  • General electronics skills (benchtop testing/debugging with oscilloscopes, logic analyzers, and other test equipment, soldering, PCB design)

  • Experience in board design, layout, fab, and bring-up

  • Experience with common serial/bus communication protocols (Ex: I2C, SPI, UARTs, CAN)

  • Strong analytical and problem-solving skills and must be able to design and conduct complex experiments.

  • Experience working in an R&D prototype development environment

  • Strong written/verbal communication and organizational skills

We encourage you to apply even if you don’t match every requirement posted for this role. No candidate will be a perfect match to our description, so if you are passionate about working on batteries, vehicle electrification, or decarbonizing energy and have similar experience to what we are looking for, we encourage you to apply. Diverse backgrounds and experiences promote innovation, and our goal is to build a team that encompasses a variety of backgrounds, experiences, and skills.
