Stratolaunch is a technology accelerator that engineers operationally realistic testing at Mach 5+. Our air-launched, Talon testbeds are reusable, cost-effective platforms that enable routine access to the hypersonic environment. We deliver flight data critical to validating system performance and achieving rapid technology deployment. Together with our customers, we drive innovations that are imperative to advancing national security. To help achieve these efforts, Stratolaunch is seeking a Sr-, Staff-, or Principal-level Mechanical Engineer to support the airframe team in the development of an air-launched, hypersonic flight vehicle development program. This position requires working within a multi-disciplined group of engineers to design, build, integrate, and test vehicles to meet customer structural requirements. An ideal candidate has significant prototype development experience, with focus in thermal-structural-mechanical design and build, leading to first flights.
