Senior Design Engineer – Power Electronics
Role Overview
As a Senior Design Engineer Power Electronics, you will be responsible for the detailed design, development, and validation of high-performance power electronic components and subsystems used in industrial automation, and renewable energy, EV Charging applications. 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 (AC-DC, DC-DC, DC-AC converters, 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.
- 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.
Required Qualifications & Experience
- M.Tech in Power Electronics specialization or related discipline
- 5 – 10+ years of hands-on experience in power electronics design, preferably in industrial domains, renewable energy, or or EVs with Power rating of 10kW and above
- Demonstrate in-depth expertise in power conversion topologies, high-voltage design practices, magnetic component design, switching devices (IGBTs, MOSFETs, SiC/GaN) selection and advanced gate drive techniques.
- Converter Hardware testing experience.
- Experience with embedded control integration and analog/digital interface design.
- Proficiency in design tools such as Cadence/Altium Designer (or equivalent), LTspice, MATLAB/Simulink, and thermal/EMI simulation platforms.
- Familiarity with hardware debugging tools including oscilloscopes, power analyzers, and thermal cameras
- Well-versed in EMI/EMC compliance, thermal management strategies, protection schemes, and safety and regulatory requirements across component and system-level design
- Experience with high-power, high-frequency switching applications and thermal/EMC mitigation strategies.
- Understand the real work requirements
Preferred Qualifications
- Experience in high-reliability industrial applications automotive, renewable energy sectors.
- Familiarity with model-based design tools and hardware-in-the-loop (HIL) testing environments.
- Self-driven, detail-oriented engineer with strong technical documentation, problem-solving skills, collaborative mind-set.
