Job Description: Power Electronics Engineer – EV Drivetrains
Location: Bangalore
Experience: 3-10 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 robust 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 creepag
