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 strong 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 systems.
• Develop and validate fault detection, diagnostics, derating logic, redundancy management, and fail‑safe operation strategies.
• Perform EMI/EMC analysis, grounding strategy development, and high‑voltage insulation coordination.
• Collaborate cross‑functionally with mechanical, thermal, controls, embedded software, systems engineering, and certification teams.
• Support compliance activities for aerospace standards including DO‑160, DO‑254, DO‑178C, ARP‑4754A, and functional safety requirements.
• Generate technical documentation including design reports, test procedures, DVPRs, qualification reports, and certification artifacts.
• Support prototype bring‑up, debugging, troubleshooting, and root‑cause analysis during development and testing phases.
