Sr. Motor Control SW/FW Engineer

Supernal is at the forefront of creating emerging mobility solutions that will foster the development of human-centered cities. We are designing a completely new electric vertical take-off and landing (eVTOL) aircraft tailored to the mobility needs of future cities. This allows passengers a seamless intermodal journey that safely transports them to their final destination. We fuse research in autonomy, robotics, aviation and services to define a new category of mobility for the world’s communities. We believe in creative thinking and collaboration to help build a better mobility experience for everyone, improving people’s ability to move – whether for work or play.

The Propulsion & Dynamic Systems team is responsible for design, integration, qualification, and certification of the energy storage system integration, high-voltage power distribution, electric motor, motor control electronics, drive systems, and rotor systems.
