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 modules for 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.
