You will perform a key analytical and modeling role in aerodynamic design, performance prediction, and trajectory optimization for our weapons systems. Working closely with multidisciplinary engineering teams, you will develop high-fidelity computational models to predict and optimize system behavior across flight profiles, ensuring alignment with program performance and mission requirements.

• Develop, validate, and execute high-fidelity CFD simulations.
• Generate aerodynamic databases and coefficients for use in 6-DoF trajectory simulations and performance models.
• Perform trajectory optimization, mission analysis, flight envelope analysis, and performance trade studies (e.g., payload-range, energy-maneuverability, endurance/loiter optimization).
• Conduct stability and control analysis, including trim analysis, dynamic stability assessments, and evaluation of stability derivatives.
• Support multidisciplinary design optimization (MDO) efforts, including integration of aerodynamic models with propulsion, structures, and controls.
• Assist engineering leadership in diagnosing performance issues, evaluating design trade-offs, and recommending optimizations.
• Prepare clear technical documentation, analysis summaries, charts, and presentations for internal reviews and external stakeholders.
• Contribute to process improvements by recommending advanced CFD methods, trajectory tools, optimization algorithms, or workflow enhancements.

• At least 5 years of experience in computational fluid dynamics (CFD) applied to aerospace systems, with demonstrated expertise in aerodynamic modeling, performance analysis, and trajectory optimization.
• Bachelor’s degree in Aerospace Engineering or a related field.
• Proficiency in CFD tools (e.g., ANSYS Fluent, STAR-CCM+, or similar) and post-processing environments.
• Strong programming skills for modeling and analysis (e.g., Python, MATLAB/Simulink, Fortran, or C++), including scripting for automation of simulations and data reduction.
• Experience generating and using aerodynamic data for trajectory simulation, mission analysis, and performance trade studies.
• Familiarity with trajectory optimization techniques, stability and control analysis, trim calculations, and stability derivatives.
• Ability to interpret engineering requirements, specifications, and aerospace standards (e.g., MIL-STD, DO-178, or similar).
• Strong analytical mindset with rigorous attention to validation, verification, and engineering accuracy.
• U.S. citizenship and ability to obtain and maintain security clearance or background-screening requirements.
• Comfortable working in a fast-paced, collaborative, team-oriented environment.

• Master’s or Ph.D. in Aerospace Engineering or related field with focus on aerodynamics or flight mechanics.
• Experience with multidisciplinary design optimization (MDO) frameworks and tools.
• Prior work on weapon systems, missiles or other defense/aerospace platforms.
• Familiarity with high-performance computing (HPC) for large-scale CFD simulations.

• Full benefits from day one: medical, dental and vision
• 401(k) with generous company match and immediate vesting
• PTO and Federal holidays
