Sr. Power Management 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 Sr. Power Management Engineer is responsible for building our power management capabilities from the ground up and assisting in developing and tracking power properties to aid with electrical loads/voltage drop development, electrical wiring interconnect system (EWIS) development, aircraft performance trade studies, cost, and more.
