Job Summary

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

Your focus as a Cell Development Engineer will be to develop and scale new cell technologies to radically improve energy density, power, safety, and/or cost vs. conventional EV technologies. Your work will take advantage of ONE’s unique hybrid pack architecture and high power-density DCDC converter, which enable the use of cells with significantly reduced life, power, and temperature requirements, accelerating the time to market of new cell and materials technologies. You will lead projects in all areas of cell research and development, including: cell evaluation and characterization, development of new cell technologies, managing both internal and external programs for cell development and scale-up for new pack products.

We are looking for passionate engineers who share our values. Our team is comprised of various integrated disciplines, including chemistry/materials, mechanical, thermal, electrical, and software. Therefore, collaboration in group settings and clear communication with people within and outside your technical discipline are critical to becoming a successful team member.

You should enjoy working on a small team where you will have substantial and critical responsibility for 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.
