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:

The Battery Pack Team is responsible for designing and prototyping high-voltage and high-power battery systems in electrified aircraft. The electronics packaging engineer for battery pack design is critical to the Energy Storage System (ESS) development process, including conceptual designs, components selection, prototype builds, and launch designs for volume manufacture.

The Sr. Mechanical Design Engineer for the Battery Pack Team will be responsible for designing the mechanical components and packaging of electrical systems. The Electric Vertical Take-Off and Landing (EVTOL) battery systems contain various electronic components such as high-voltage printed circuit boards, flex circuits, cable harnesses, laminated bus bars, and sense circuits. This role will oversee the mechanical design and protection of these electronic components for the Supernal battery pack designs. The Sr. Mechanical Design Engineer will work closely with battery systems, test, and product integration engineers to ensure that a robust ESS is designed, built, and integrated into the eVTOL aircraft.

This position will be required to work on-site 5 days a week.

What you can do:

• Drive mechanical design of electrical components, interconnects, and electromechanical subsystem designs from conceptual and requirements development through production
