Sr. Propulsion Engineer

**Position Summary** 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 achieve these efforts, Stratolaunch needs a Senior Propulsion Engineer to design various fluid system components and assemblies for the integration of rocket propulsion systems. Tasking will include the design of fluid plumbing systems, the integration of rocket feed system valves and tanks, and the test of propulsion components and subassemblies. An ideal candidate will have both mechanical and fluid subsystem component design experience. You must be comfortable with supporting your design through the entire design life cycle – from concept through integration and test. This position will include evaluation of a broad range of technical data. Candidates must have an aerospace development background and relevant experience in aerospace systems integration. **ESSENTIAL RESPONSIBILITIES** + Lead the development, build, and test of propulsion flight and ground hardware + Perform structural, fluid, and thermal analysis of mechanical components and/or assemblies + Create component and assembly drawings for all hardware + Create and maintain work instructions to install flight hardware onto vehicles + Assist mechanics in integrating all components and assemblies onto the aircraft and/or ground systems + Test propulsion components and/or assemblies to prepare for integrated subsystem testing + Develop engineering tools, as needed, to complete their tasking + Regular and comprehensive communication to the Propulsion Lead + Contribute to the integration of complex aerospace systems + Travel, as needed, to support the department + Demonstrate honesty, responsibility, integrity and fulfillment of commitments **QUALIFICATIONS** + Knowledge of, and experience with, one or more of these disciplines: fluid subsystem design, mechanical design, structural engineering, component or assembly level mechanical or fluid testing, rocket testing, cryogenic fluid systems, electrical and/or instrumentation experience + Experience with aircraft prototype development, including releasing engineering definition and developing work instructions + Experience with fluid-mechanical component design and stress analysis + Experience with component-level or subsystem level test planning and execution + Experience with aircraft and prototype integration and testing + Ability to communicate technical challenges and guidance to varied audiences to explain rationale and/or resolve concerns + Ability to work on their own initiative and prioritize tasking to fit within the business goals + Complex aerospace system development + Ability to quickly adapt to changing priorities **EDUCATION & EXPERIENCE** + Bachelor’s degree (B.S.) from accredited institution and 5-plus years of engineering experience, OR equivalent combination of education and experience **Special remarks regarding work environment, if applicable** + This position is located in Mojave, CA + Travel, as needed, to support the department.
