What you will do

• Design, build, and maintain high-fidelity 1D multiphysics models of electric powertrains, including batteries, inverters, electric motors, and thermal management systems.
• Run standard and custom simulations for hover, climb, dynamic pulse loading, continuous discharge, and extreme temperature conditions.
• Conduct trade studies and sensitivity analyses covering component sizing, gear ratios, voltage levels, and thermal cooling strategies.
• Correlate simulation results with Dyno and Battery Lab test data to improve model accuracy and reliability.
• Provide plant models for control algorithm development and SIL/HIL testing.
• Automate simulation execution, data processing, and performance report generation.

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or a related technical field.
• 2+ years of hands-on experience in simulation, modeling, or systems engineering focused on electric powertrains, thermal systems, or battery performance.
• Experience with 1D multiphysics tools such as GT-SUITE, Siemens Amesim, MATLAB/Simulink/Simscape, or Dymola/Modelica.
• Strong knowledge of thermodynamics, heat transfer, electrochemistry, electric motor dynamics, and electric powertrain fundamentals.
• Proficiency in Python or MATLAB for data analysis and simulation automation.
• Ability to interpret physical test data and translate hardware behavior into mathematical models.

Nice to have

• Experience with aerospace, drone, or eVTOL hardware, flight physics, and high-power mission profiles.
• Familiarity with 3D CFD/FEA tools such as ANSYS or Star-CCM+ and extracting data for 1D system models.
• Experience taking a powertrain architecture from clean-sheet concept through hardware validation.
