Senior/Staff Systems Modeling Engineer, Electric Propulsion

Responsibilities

• Own the electric-propulsion modeling roadmap, framework, validation standards, and deployment of validated models across aircraft programs.
• Lead trade studies that inform propulsion architecture, sizing, operating limits, thermal management, control strategies, and performance optimization.
• Develop and validate physics-based models of electric propulsion systems across multiple levels of fidelity, supporting aircraft simulation, hardware design, controls development, and fleet operations.
• Design and lead characterization campaigns for parameter identification and model validation, defining test requirements, instrumentation, and procedures for dynamometer, thrust stand, wind tunnel, and thermal testing.
• Build and own clean, modular, object-oriented modeling frameworks and engineering tools that are maintainable, reusable, and scalable across aircraft programs.
• Continuously improve model fidelity by comparing predictions against laboratory testing and production flight data, identifying model deficiencies, and deploying validated improvements that increase predictive accuracy across the fleet.
• Partner closely with electrical, mechanical, thermal, controls, flight test, manufacturing, and fleet operations teams to translate modeling insights into better products and engineering decisions.

Requirements

• 8+ years of industry experience developing and validating physics-based models for electric powertrains, aerospace systems, electric vehicles, robotics, or other complex electro-mechanical systems.
• Strong heat-transfer fundamentals and experience building, parameterizing, and validating lumped-parameter thermal networks for electric machines or power electronics.
• Track record of using quantitative analysis and modeling to drive engineering decisions, including design trade studies, operating limits, performance optimization, or system architecture decisions.
• Demonstrated ability to design experimental characterization campaigns for parameter identification and model validation, including defining test plans, instrumentation, and measurement requirements.
• Proficiency in MATLAB, Python, Julia, Rust, or similar languages, with experience developing clean, modular, object-oriented engineering code and reusable modeling frameworks.
• Solid foundation in numerical methods, optimization, controls, and engineering model validation.
• Excellent communication and collaboration skills, with the ability to influence cross-functional engineering decisions through quantitative analysis.
• Ability and willingness to work onsite with cross-functional engineering teams. This role requires regular hands-on collaboration with hardware, testing, and flight operations.

Nice to have

• M.S. or Ph.D. in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or a related field.
• Familiarity with motor and inverter loss mechanisms and modeling approaches.
• Experience using high-fidelity electromagnetic and thermal simulation tools such as ANSYS Motor-CAD, ANSYS Maxwell, JMAG, COMSOL, ANSYS Icepak, or similar.
• Familiarity with production telemetry, fleet operations, or hardware test data for engineering model validation and continuous improvement.
