Full-time/Permanent Employee
Location: Dayton, OH (Travel: Up to 30% within continental United States)

Our client is seeking a Senior Propulsion Engineer to support the NOVASTAR program. This position will support a broad range of work involving the guidance, navigation, propulsion, control, software, modeling, and simulation of rocket-propelled aerospace vehicles.

The selected candidate will be responsible for addressing customer inquiries related to propulsion systems, including liquid rocket engines and solid rocket motors. Additionally, the candidate will be expected to formally respond to these inquiries through technical reports based on professional experience, background research, professional propulsion databases, rudimentary design analyses, and other technical resources.

The candidate must be able to work autonomously with minimal guidance. On occasion, the candidate will also be expected to contribute to collaborative technical reporting for our customers.

Clearance: Active TS/SCI Clearance
Education and Years of Experience: Bachelor's Degree in Aerospace Engineering or Mechanical Engineering from an ABET-accredited university and 5+ years of demonstrable experience in the design, testing, or evaluation of propulsion systems or fluid mechanical systems.

Formal education or training in the following propulsion-related topics:

Thermodynamics, with an emphasis on thermal and chemical equilibrium
Stoichiometry
Quasi-one-dimensional (1D) and two-dimensional (2D) compressible flow
Basic rocket nozzle design theory
Structural mechanics
Classical mechanic
Demonstrable proficiency in scientific computing for mechanical or aerospace engineering analyses using one or more programming languages (e.g., C, C++, Fortran, Python, MATLAB).

Master's degree in Aerospace Engineering or Mechanical Engineering from an ABET-accredited university, with an emphasis on chemical rocket propulsion.

Recent TS/SCI eligibility.

Eight (8) or more years of professional experience in the design, testing, or evaluation of propulsion systems, with an emphasis on liquid rocket engines or solid rocket motors.

Professional experience utilizing propulsion databases maintained by JANNAF.
