Principal Propulsion Engineer

Astrobotic is at the forefront of advancing space exploration and technology development. Our expertise spans from lunar rovers, landers, and infrastructure to spacecraft navigation, machine vision, and computing systems for in-space robotic applications. To date, the company has been contracted for two lunar missions, and has won more than 60 National Aeronautics and Space Administration (NASA), Department of Defense (DoD), and commercial technology contracts worth more than $600 million.

We recently launched and operated the first American lunar lander mission since the Apollo Program. Beyond helping lead America back to the Moon, Astrobotic developed and operates reusable vertical takeoff, vertical landing (VTVL) rockets and continues to advance next-generation VTVL capabilities and advanced rocket engines. Established in 2007, Astrobotic is headquartered in Pittsburgh, PA, with a propulsion and test campus in Mojave, CA.

This position will help lead the technical development and evolution of Astrobotic's portfolio of VTVL propulsion technologies and testing capabilities.  This position requires significant propulsion system design and analysis as well as extensive hands-on prototyping and testing experience, ideally including engine testing and flight operations.  Significant experience with bi-propellant cryogenic propulsion systems is required.   This position is part of the propulsion team located in Mojave, CA and will collaborate with the spacecraft propulsion team located in Pittsburgh, PA.
