Civil Engineer

Archer is an aerospace and defense company headquartered in San Jose, California, building the aircraft and technology that will define the next era of flight. The company works across air taxis, UAS, AI and powertrain development — building real-world systems that combine software intelligence with physical hardware. That includes Midnight, Archer's all-electric air taxi; Halo, an autonomous vertical takeoff and landing aircraft built for both commercial and defense use; and ZEE, Archer's AI foundation model built specifically for aviation. We’re seeking exceptional engineers, operators and builders to join us on our mission to build the future of aerospace and defense.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.Join Archer Aviation's Mass Properties team and play a critical role in bringing electric vertical takeoff and landing (eVTOL) aircraft from concept to certified reality.
