Hardware-in-the-Loop (HIL) Engineer, Energy Storage (San Francisco)

Overview

Hardware-in-the-Loop (HIL) Engineer, Energy Storage

About Redwood Materials: Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling keeping critical minerals in circulation and driving the energy transition. Founded in 2019, were delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.

Hardware-in-the-Loop (HIL) Engineer, Energy Storage

You will be an early member of the Redwood Energy engineering team, taking a hands-on role in the design, development, and integration of second-life battery-based energy storage systems. This role will be the first engineer on the Hardware-in-the-Loop team, in charge of developing the hardware and software architecture that allows us to quickly develop and release hardware and software with confidence in critical safety and performance requirements and still meet project goals. We believe the best way to do this is with an intentionally designed, automated system that works closely with the entire product development team.

The ideal candidate is comfortable across both hardware and software, has coding or scripting experience, and is comfortable reading schematics and using an oscilloscope. If you have been designing HIL setups for years and have strong opinions about the ecosystem we want to hear them, but we also think an early career engineer with strong first-principles understanding and motivated by this problem can be successful. Most importantly, we are looking for someone highly self-driven, adaptable to a startup environment, and eager to take on novel technical challenges. If youre excited about working in a dynamic, fast-paced setting within a new department at Redwood, we want to hear from you!
