Job Description

Job Description: Power Electronics Engineer – EV Drivetrains

Location: Bangalore 

Experience: 7-10 years

About the Role

We are looking for a Power Electronics Hardware Engineer to support the development of high-voltage EV drivetrain electronics for our X-in-1 integrated powertrain systems. The role involves hardware design, component selection, schematic development, PCB design coordination, prototype bring-up, validation support, and system integration for 400 V and 800 V EV power electronics platforms.

The engineer will work on key subsystems such as the Motor Control Unit/Inverter, PDU, On-Board Charger, DC-DC Converter, DC bus architecture, gate driver circuits, sensing circuits, power supplies, protection circuits, and system-level hardware integration.

This role is suitable for candidates with strong fundamentals in power electronics hardware design, EV high-voltage systems, analog/digital circuits, semiconductor devices, and product development from concept to functional prototype.

Roles and Responsibilities

  • Design and develop hardware for 400V EV power electronics systems including Motor Control Unit/Traction Inverter, Power Distribution Unit, On-Board Charger, DC-DC Converter, DC Bus interconnect architecture, X-in-1 system level integration
  • Perform detailed hardware architecture definition based on system requirements, vehicle requirements, power ratings, thermal limits, safety requirements, and packaging constraints.
  • Select suitable components for high voltage EV applications, including IGBT/SiC/MOSFET, Gate Drivers, DC Link Capacitors, Sensors, Sensing circuits, contactors, fuses, magnetics, EMI/EMC filters, Busbars, etc
  • Carry out component derating analysis and prepare design calculations
  • Develop detailed schematics for power stages, gate drivers, sensing paths, auxiliary power supplies, protections, control cards, comm interfaces, HVIL and safety circuits
  • Work closely with PCB layout engineers for – high current layout, high voltage creepage and clearance, loop optimisations, EMI-EMC sensitive routing, isolation barriers, vias and copper balancing, groundings, etc.
