About The Position

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff and landing aircraft with a mission to advance the benefits of sustainable air mobility. We are designing, manufacturing, and operating an all-electric aircraft that can carry four passengers while producing minimal noise. Our sights are set high and our problems are hard, and we believe that diversity in the workplace is what makes us smarter, drives better insights, and will ultimately lift us all to success. We are dedicated to cultivating an equitable and inclusive environment that embraces our differences, and supports and celebrates all of our team members. 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. Our strategy has been and continues to be to hire top talent across various disciplines to build the best products and deliver the best services possible. We believe we have assembled a world-class team with extensive experience across the key disciplines. We embrace collaboration and creativity and encourage the iteration of ideas to address the complex challenges our industry faces. We believe our team and culture differentiates us versus our competitors and will be a key driver of our long-term success. Furthermore, we are committed to making safety a part of everything we do. Our approach to safety is a part of every aspect of our company , from design and engineering to our manufacturing, flight test, and aircraft operations
