we are looking for a Electric Propulsion Engineer.
What you'll own:
Design and analyze motor electromagnetics with torque ripple, cogging torque, and radial force harmonics treated as hard requirements alongside efficiency and power density.
Develop inverter modulation and current-control strategies – including harmonic injection and active ripple compensation – that suppress electromagnetic excitation before it becomes radiated tone.
Build and validate multiphysics models chaining electromagnetic force prediction through structural transfer paths to radiated noise, correlated against dyno and vehicle data.
Plan and execute dyno test campaigns with synchronized electrical, vibration, and acoustic instrumentation, owning the data pipeline from raw capture to engineering verdict.
Integrate motors, inverters, and mounts into the vehicle's novel lift and propulsion architecture, working structure-borne transmission paths jointly with the Structures and Acoustics teams.
Characterize thermal behavior on the dyno and derive continuous and peak torque envelopes that hold across the full flight profile.
Define acceptance and qualification test procedures for propulsion units, including back-EMF, efficiency-map, vibration, and acoustic signature checks.
Lead propulsion design reviews and hardware failure investigations, driving root cause to closure with documented corrective actions.

Requirements:
B.Sc. or M.Sc. in Electrical or Mechanical Engineering with a focus on electric machines, power electronics, or drives.
5+ years designing electric motors or motor drives for demanding applications – aerospace, automotive traction, robotics, or similar.
Deep working knowledge of electric machine noise mechanisms: torque ripple, cogging, radial force harmonics, and PWM sideband tones, and how to design them down.
Hands-on experience with field-oriented control and modulation schemes, including controller implementation and current-loop tuning in MATLAB/Simulink or PLECS.
Proficiency with electromagnetic FEA tools such as ANSYS Maxwell, Motor-CAD, or JMAG, including loss and force-harmonic prediction.
Demonstrated dyno or rig test experience: instrumentation selection, data acquisition setup, and debugging real hardware under load.
Strong Python or MATLAB skills for test data reduction, order analysis, and model correlation.
Comfortable owning hardware end to end – requirements through test – in a small team moving at startup pace.
