Cell Engineering Manager

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 Cell Engineering Manager will focus on developing the cell engineering team for Energy Storage Systems (ESS). The primary responsibility of this role will be to build our labs and other testing capabilities to qualify internal and external cell programs for use in various aircraft. Additionally, the Cell Engineering Manager will be tasked with building our data science, cell testing, and algorithms team to create a complete value chain for cell engineering. Finally, they will provide leadership and management to a group of cell test engineers and equipment engineers.
