Senior Engineer, Aeronautical Modeling & Simulation (Dallas/San Diego) (R4538)

JOB DESCRIPTION:

The Software Integration & Operations (SIO) group turns frontier autonomy into mission-ready aircraft. We own the commit-to-flight pipeline—deterministic aircraft and mission simulation, HIL/VIL integration, CI/CD, automated flight qualification testing, and release engineering. Our goal is simple: make AI fly—safely, repeatably, and fast.  

As a Modeling & Simulation Engineer, you will be responsible for improving and adding to our world and aeronautical models so that our operator training and internal engineering pipelines have a seamless translation from sim to real results. 

• Develop and enhance aeronautical physics models (aerodynamics, propulsion, environmental, structural, etc.) for use in simulation and evaluation. 
• Translate theoretical models into efficient, reliable C++ implementations with a focus on numerical accuracy and performance. 
• Validate models against real-world data and authoritative references, including field test data and calibration procedures. 
• Collaborate with simulation and training application teams to ensure models integrate cleanly into operator-facing tools. 
• Design automated validation and regression testing strategies for mathematical models to ensure fidelity across releases. 
• Prototype and evaluate new modeling techniques (reduced-order models, uncertainty quantification, machine learning–based surrogates) to push the state of the art. 
• Document assumptions, equations, and validation results so that both engineers and operators can trust model outputs. 

•  BS or higher in Aerospace Engineering, Applied Math, Physics, or related field with 1+ years of aerospace modeling experience. 
• C++ foundation with experience implementing numerical methods. 
• Demonstrated experience with aerospace models such as: Aerodynamics (lift/drag curves, stability derivatives, dynamic response), Atmosphere/environment (COESA, ICAO, gravity, wind models), Vehicle dynamics 

• 1+ years of experience working on pilot/operator training systems. 
• Experience with Eigen or SciPy for model prototyping and validation. 
• Familiarity with state estimation sensor models (GPS, IMU, Gyro, etc) for simulation environments. 
• Background in multi-body dynamics or flight mechanics
• Knowledge of uncertainty quantification and statistical analysis methods. 
• Strong problem-solving mindset with a collaborative and detail-oriented approach. 
• Familiarity with Python for test automation and data analysis pipelines. 
• Passion for aerospace and autonomous vehicle systems.
