Senior Software Engineer, Battery Management System

Senior BMS Software Engineer

San Jose, CA

We are developing the technologies and aircraft to power the future of advanced aviation. We plan to provide customers with advanced aircraft and. related technologies and services in the United States and internationally in both the commercial and defense sectors. We unveiled our first planned production aircraft, an electric vertical take-off and landing (“eVTOL”) air taxi, called Midnight, in November 2022. In December 2024, we launched Archer Defense, to develop a next-generation aircraft for both defense and civilian applications. We are first and foremost working to commercialize our Midnight air taxi in and around major cities around the world.
