Senior/Staff Power Electronics Engineer, Power Conversion

Tau is a venture-backed advanced technology company based in the Bay Area (Redwood City, CA). We design and develop next-generation products for electrification, constantly pushing the boundaries of innovation. The company was started because we believe the key to a more sustainable future requires modern power conversion systems to increase the security of the world’s energy.

We have pioneered technologies that leverage software-enabled hardware to provide industry-leading scale, economics, and efficiencies. Our systems include innovations across electric machines, inverters, controllers, thermal management, simulation, and charging systems. Tau's team of engineers, scientists, technologists, operators, and industry leaders continues to advance our internal technology roadmap while collaborating with commercial partners to deploy our existing products to market.

They are relentlessly pursuing the creation of efficient power conversion systems for a more sustainable future. At our core, Tau is made of exceptionally talented and mission-aligned people. Developing complex electromechanical systems is an interdisciplinary challenge.

We want to expand our team with diverse engineering, scientific, and operational expertise. About you We are looking for people who aren't afraid to take on new challenges and are as passionate about energy and electrification as we are: You find significant challenges exciting and enjoy discovering and defining problems as much as solving them. You deliver .

You may enjoy thoughtful conversations about problems and perfecting design, but ultimately, you know that delivering innovative, effective, and reliable solutions matters. You are a cross-disciplinary team member . You are excited to work with, learn from, and contribute to technology teams ranging from electromagnetics, power electronics, controls systems, mechanical, materials, software, computational physics, and beyond.

About The Role

We seek an experienced and highly accomplished Senior/Staff Power Electronics Engineer to join our innovative team at Tau Motors. In this crucial role, you will spearhead the design, development, and implementation of cutting-edge power electronics systems for next-generation electric vehicles and energy storage solutions. As a critical member of our power electronics team, you will drive the modeling, architecture, and validation of advanced power converter topologies, contributing significantly to Tau's technology roadmap and product offerings.
