The Missile Propulsion Systems Analysis Department in West Palm Beach is seeking an experienced engineer for a full‑time position to support the Advanced Concepts organization within the Hypersonics Business as a pathfinder group.

The Mission Architecture & Advanced Concepts Engineer will work with senior engineers to conduct rapid, high‑fidelity advanced concept air‑breathing analyses using proven process flows and methodologies. This engineer will perform integrated trajectory/vehicle/propulsion analysis and design optimization for hypersonic and high‑speed air‑breathing propulsion systems including Solid Fuel Ramjet (SFRJ), Liquid Fuel Ramjet (LFRJ), Dual Mode Ramjet (DMRJ), and Rotating Detonation Engine (RDE) cycles.

The engineer will develop conceptual and preliminary designs, conduct trade studies of complex and innovative propulsion systems, and support Business Development and Internal Research and Development (IRAD) activities.

• 40% – Conduct advanced concept thermodynamic design and mission architecture analyses for air‑breathing propulsion systems. Develop and use integrated propulsion system models including NPSS propulsion performance models, MATLAB/Simulink, Model Center, trajectory analysis tools (POST, Quickshot, OTIS), Python, C/C++, and FORTRAN. Perform inlet/engine/airframe matching analyses and trajectory optimization. Conduct sensitivities and Monte Carlo analyses to support concept evaluation and risk reduction. Create concepts of operation, requirements development, and initial system architectures for advanced hypersonic concepts.
• 40% – Generate advanced designs and conduct performance analyses for liquid and solid rocket propulsion concepts and air‑breathing engines. Develop configuration layouts and mass properties using CAD tools (Creo/NX). Create and maintain math models of propulsion systems characterizing thermodynamic, aerodynamic, fluid dynamic and mechanical operation. Utilize CFD tools for external aerodynamics, inlet performance, and nozzle analysis. Perform aeroheating analysis and stability & control assessments.
  
  Design and analyze engine control systems and control logic for solid fueled, liquid fueled, and air‑breathing engines.
• 20% – Support Business Development activities including RFI/RFP responses, white papers, and customer briefings. Prepare and deliver technical presentations to cross‑functional and integrated product teams. Lead peer reviews and participate in technical proposals describing design approach, relevant heritage, risk assessment and mitigation planning.
