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.
The Principal Propulsion Engineer will be a critical contributor to the design, test, and integration of the propulsion systems for Astrobotic’s lunar lander product lines. You will be responsible for working directly on the design and analysis of the propulsion systems, from initial component sizing to system layout and modeling through to supporting mission operations. You will regularly report to the Propulsion Lead on progress.
