Serve as a Principal Engineer for the Contested Autonomy and Navigation team in Huntsville, AL. Our team’s mission is to: (1) develop and demonstrate contested autonomy and navigation technologies to meet urgent military operational needs to operate in contested, RF-challenged environments, and (2) rapidly transition this technology to operational platforms to outpace real-world adversary threats. We support a variety of military autonomous vehicles including drones, unmanned underwater vehicles, and ground robots. Projects involve small teams of engineers working together to meet aggressive customer schedules aimed at near-term field demonstrations of emerging capabilities. Typical customers include Defense Advanced Research Projects Agency (DARPA), Air Force Research Laboratory, Office of Naval Research (ONR), and Army engineering research centers.
We are looking for an individual who enjoys leading teams and growing new work while also “keeping hands dirty” writing software and touching hardware. The position will involve a mix of direct and indirect work focused on development of innovative solutions related to autonomous behavior generation, object detection, multi-vehicle collaboration, and GPS-denied navigation for autonomous vehicles.
