• Significant experience developing or applying aircraft-level models and simulations.
• Strong understanding of aircraft performance, flight mechanics, dynamics and multidisciplinary system interactions.
• Experience integrating models from aerodynamics, structures, propulsion, electrical, controls, or thermal disciplines.
• Proficiency with MATLAB/Simulink, Python, C/C++ or equivalent.
• Experience conducting trade studies, parameter sweeps, sensitivity analyses, uncertainty quantification, or optimization.
• Demonstrated ability to convert simulation results into actionable aircraft, design recommendations.
• Experience with model verification, validation, test correlation, and configuration control.
• Strong technical leadership and cross-functional communication skills.

Responsibilities

• Own the architecture, development, and validation of integrated aircraft simulations.
• Use simulation to guide aircraft configuration, subsystem sizing, requirements, and design trade studies.
• Integrate aerodynamic, structural, propulsion, electrical, mass-properties, controls, and mission-performance models.
• Lead multidisciplinary design optimization and sensitivity analyses.
• Quantify design margins, uncertainty, risk, and system-level impacts of proposed changes.
• Define simulation fidelity requirements appropriate to each phase of development.
• Establish model verification, validation, configuration-management, and documentation practices.
• Correlate simulation results with component tests, ground tests, and flight-test data.
• Develop representative mission profiles and evaluate aircraft performance across expected operating conditions.
• Identify system interactions, integration risks, and performance constraints early in the design cycle.
• Present recommendations and trade-offs to technical leadership and program stakeholders.
• Mentor engineers and establish best practices for simulation-driven aircraft development.
• Support requirements development, architecture reviews, design reviews, and certification activities.
