We believe in a world where less time getting there means more time being there, and that starts with Cora. 
With over a decade of piloted and autonomous flight experience, we’ve created Cora—our all-electric, self-flying air taxi that will change the future of daily commutes and urban travel. From day one, Cora by Wisk was designed with safety as our first priority using emissions free systems.

We’re working toward a future where you’ll be able to safely soar over traffic and get to where you’re going, faster. Because everyone has somewhere to be, someone to see, and now—a better way to get there.

This position contributes to the development and qualification of novel battery technology for current and future Urban Air Mobility eVTOL projects. You will join a small team of like-minded engineers and scientists designing and sourcing cells from strategic battery cell suppliers, generating test plans, analyzing test data, and presenting that data to a wide multi-disciplined audience to help make vehicle-level decisions.
