Sr. Mass Properties 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. Mass Properties Engineer is responsible for building our Mass Properties analysis capabilities from the ground up and assists in developing and tracking aircraft mass properties to aid with loads development, structural analysis development, aircraft performance trade studies, cost, and more. This position requires a professional with expertise in Mass Properties analysis and control during different phases of design/development to certification.
