Job Description

Power Electronics Design Engineer – Traction Converter (P10)

Role Overview

As a Power Electronics Design Engineer, you will be responsible for the detailed design, development, and validation of high-performance power electronic components and subsystems used in traction converter for EV power trains. You need to translate system-level requirements into schematics, prototypes, and production-ready designs, playing a key role in bringing cutting-edge power electronics solutions to life.

Key Responsibilities

Design and develop power conversion circuits and modulesfor traction inverters, gate drive and protection circuits) based on system-level specifications and requirements.
Perform detailed schematic capture, PCB layout guidance, and component/device selection for high-efficiency power circuits.
Perform simulation, analysis, and optimization of power stages, switching topologies, thermal performance, and EMI/EMC characteristics, filter design using tools such as LTspice, PLECS, and MATLAB/Simulink and hardware testing to validate designs.

Design:

High-voltage DC-AC traction inverter
DC-DC converters in vehicle platforms
Semiconductor selection (SiC MOSFET / IGBT modules)
Gate driver circuit design (dv/dt immunity, Miller clamp, short-circuit protection)
Switching loss & conduction loss modelling
Thermal modelling and cooling strategy definition
Magnetics and busbar design optimization
Optimize design for motor control algorithms, various drive cycles like WLTP, MIDC
Support EMI/EMC mitigation, thermal management, and protection strategy implementation.
Collaborate with cross-functional teams (firmware, mechanical, testing, manufacturing) to ensure seamless integration and validation of designs.
Provide inputs for concept design, packaging and development of the product.
Support prototype bring-up, lab testing, and power bench measurements while driving root cause analysis and iterative debugging during validation, field trials, and production ramp-up
Develop test jigs for the testing of the products.
"Generate and maintain comprehensive technical documentation—including schematics, BOMs, layout files, design reports, validation records, and change logs—to ensure traceability and design integrity throughout the development lifecycle
Support and participate in design reviews, DFMEA/DFM activities, and failure analysis investigations, contributing to the refinement of design standards and continuous improvement of engineering practices
Ownership of design deliverables with strong communication skills, fosters effective collaboration across multidisciplinary teams, and maintains a commitment to continuous learning and engineering excellence.
