Job description

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.
