The engineer will work in a team environment to develop digital engine control logic and schedules to support Program development activities. Essential Functions 40% - The systems analyst primarily will perform advanced concept thermodynamic design of air‑breathing engines to define propulsion cycles that meet functional vehicle requirements. During the development activities of these propulsion systems, the systems analyst will primarily conduct performance analyses and evaluate the steady state and transient operation of these propulsion systems. Duties may include development of conceptual/preliminary designs and perform trade studies of significant, complex, innovative and advanced propulsion and technology systems to meet customer requirements. Create concepts of operation, requirements development, and initial system architectures for advanced concepts. Develop and use integrated propulsion system models for sizing, performance, and analysis including NPSS propulsion performance models, MATLAB/Simulink, ModelCenter, computer aided design (CAD) tools, trajectory analysis tools, Python, C/C++, SysML, and FORTRAN. Duties may include evaluation of ground test and flight data to determine engine health and conformance to performance requirements. 40% - Duties will include creating, maintaining and using math models of propulsion systems which characterize the thermodynamic, aerodynamic, fluid dynamic and mechanical operation of these systems. Alternatively, duties will include designing and testing engine control systems and control logic for liquid rocket and/or air‑breathing engines. 20% - Propulsion development activities include contributing technical analyses to anomaly investigation and resolution teams. As required, provide on‑site customer technical support for engine ground test coverage and analyses, and system flight test activities. Willingness and ability to travel up to 10%. Qualifications Bachelor’s Degree and minimum 4 years of prior relevant experience. Graduate Degree and a minimum of 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience. Active Secret Security Clearance Preferred Additional Skills Bachelors or Masters Degree in Aerospace Engineering or equivalent. Proficiency in NPSS propulsion performance models, MATLAB/Simulink, ModelCenter, computer aided design (CAD) tools, trajectory analysis tools, Python, C/C++, SysML, and FORTRAN. Proficiency in Model Based Systems Engineering (MBSE) tools. Experience with engine control system design, test, and analysis. Communication and presentation experience with cross‑functional and integrated product teams. Knowledge and experience with air‑breathing high‑speed propulsion systems used in defense applications. Experience with System Analysis, including modeling & simulation, performance & operability analysis, engine control operation & design is desired.
