  • Overview

    As part of a small, passionate and accomplished team of experts, you will prototype, design, develop, and test propulsion technologies and devices for various electric, nuclear, and liquid rocket engines. You will work with a world class team of experts in propulsion devices and help expand our presence beyond low Earth orbit, developing sustainable access architectures to space and planetary surfaces.  You should be comfortable working in a fast-paced and often uncertain environment, contributing to innovative solutions, while demonstrating personal leadership, technical competence, and attention to detail. This position will directly impact the history of space exploration and will require your dedicated commitment and detailed attention towards safe and repeatable spaceflight.


    • Conduct research and prototype development (analytical, computational, experimental) of propulsion devices for launch, in-space, and planetary lander systems.
    • Support configuration design studies and develop prototype propulsion systems.
    • Interface with mission and trajectory designers to develop requirements for future systems.
    • Develop detailed designs, procure components and materials and conduct testing to demonstrate system performance.
    • Plan, conduct, and technically direct projects, coordinating the efforts of a small team or contractor as needed. Monitor and report on progress.
    • Correlate results to test data to provide accurate predictions of future system performance.
    • Support sales and business development activities, including the development of technical proposals.


    • M.S. in Electrical, Nuclear, Aerospace, Mechanical, or related engineering field
    • 10+ years of experience in electric, nuclear, or chemical rocket engine propulsion devices
    • Comprehensive knowledge and hands-on experience in designing, testing, and flying propulsion systems for launch, in-space, and planetary lander systems
    • Working knowledge of electric, nuclear, or chemical rocket engine subsystems including pumps, valves, turbomachinery, reactor cores, fluid systems, and electronics
    • A strong background in thermodynamics, fluid systems, power systems, and/or nuclear engineering
    • Demonstrated experience in the entire design cycle of propulsion devices including trade studies, design and analysis, production, assembly, test support and data review
    • Ability to communicate technical information effectively
    • Ability to work effectively both independently and as part of a team
    • Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.


    • Ph.D. in Electrical, Mechanical, or Aerospace engineering
    • Hardware development experience including assembly, fabrication, verification and test
    • Demonstrated advanced knowledge in in-space nuclear or electric propulsion technologies
    • Proficiency in programming; knowledge of Python, MATLAB, or FORTRAN
    • Knowledge of ROCETS, NPSS, GFSSP or an equivalent system modeling software package
    • Solid system engineering and configuration management skills
