Job Description:
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. What we do: We
have embarked on a mission to support the creation of a
ground-breaking future in urban air transportation using eVTOL
(Electrical Vertical Takeoff and Landing) aircraft. We believe that
innovation and creativity at each step in the development process
are the keys to bring solutions that help to improve the lives of
common people. If you are a person who does not accept the status
quo in this regard and wants to be part of crafting this exciting
new future along with us, this is where you belong.We work on the
cutting-edge of Battery Technology to build a state of the art,
