About The Position

At Wisk, we're transforming the future of urban mobility through safe, all-electric, autonomous flight. We are a passionate team working together toward a sustainable future, solving high-impact problems that have never been solved before. By delivering everyday flight for everyone, we're making it possible to spend less time getting there and more time being there. If you want to be part of shaping the future of mobility, then read on! We are looking for a Staff Power Electronics Engineer to join our team. The goal of this role at Wisk is to ensure that we design safe and reliable high power electronics for the aircraft. You will be part of the Propulsion team in the Powertrain IPT. This is a hybrid work opportunity. At Wisk, this means working onsite at our Mountain View office 3 days per week with flexibility for the remainder of the days. What you will do: As part of the Powertrain IPT organization and deployed in the Motor Controller Hardware Team, you will act as a seasoned engineer and designer focused in the design and development of low/high voltage electronics for a high power inverter. You will take part in designing high reliability power architectures and control electronics in accordance with relevant military standards, DO-254 standards, FMEA analysis, and tight tolerance/temperature restraints. You will support motor controller testing, dyno testing, propeller testing, and also aircraft testing as an expert in power electronics. You will take ownership of designs and oversee all aspects of lifecycle development including but not limited to: concept, board design, multi-functional team coordination, deployment of design into product lifecycle management (PLM) software, design verification testing, standardized documentation, requirements verification, and troubleshooting of issues during experimentation. You will regularly coordinate with teams outside of the Motor Controller Team (mechanical, thermal, flight bus, systems, safety) and design to requirements as needed to meet goals of other IPTs. You will help conceptualize designs that optimize the weight and power density of the propulsion unit.
