Job Summary
- We are hiring a Power Electronics Design & Validation Engineer to lead the design, development, tuning, integration, and validation of high-voltage, high-power propulsion inverter systems for next-generation eVTOL platforms. The role involves end-to-end ownership of propulsion inverter hardware, motor control algorithms, system integration, controller tuning, verification & validation, and powertrain testing activities. You will work on 600–1000V class electric propulsion systems involving SiC-based inverters, high-speed electric motors, thermal management, EMI/EMC, functional safety, and aircraft-level powertrain integration. The ideal candidate should have robust expertise in power electronics design, motor control, system-level validation, and hardware/software integration for aerospace or high-performance EV applications.

Key Responsibilities
- Lead the architecture, design, development, and validation of high-voltage propulsion inverter systems for eVTOL applications.
- Design and optimize high-power inverter hardware including DC-link capacitors, gate drivers,



busbars, current sensing, protection circuits, and SiC/MOSFET power stages.
- Develop motor control strategies including FOC, MTPA, field weakening, torque control, regenerative braking, and fault management.
- Perform controller tuning and calibration for propulsion motors under dynamic flight operating conditions.
- Conduct simulation and modelling activities using MATLAB/Simulink, PLECS, LTspice, PSIM, or similar tools for inverter and motor drive systems.
- Define and execute verification & validation plans for propulsion inverters, motor controllers, and integrated electric powertrain systems.
- Support HIL, SIL, MIL, and dyno-based testing activities for propulsion systems and perform correlation between simulation and experimental results.
- Lead system integration activities involving motors, batteries, BMS, thermal systems, avionics interfaces, and aircraft power distribution syst
