Job description

Job Description - Power Electronics Design Lead

Role overview

Lead the end-to-end development and integration of advanced power electronic systems for electric vehicles, renewable energy, and industrial automation. Champion system architecture, cross-functional collaboration, and adherence to global safety and performance standards. Resolve complex system-level challenges- including thermal, EMI/EMC, and functional safety- while mentoring engineering teams and fostering a culture of innovation, quality, and continuous improvement throughout the product lifecycle.

Key Responsibilities

• Lead the development and integration of power electronic systems- including AC-DC, DC-AC, and DC-DC converters, inverters,- for electric vehicles, renewable energy platforms, and industrial converters.
• Define system architecture, topology, requirements, and interface specifications for industrial power converters, charging platforms, high-voltage drivetrain systems.
• Guiding designs from concept to mass production.
• Collaborate cross-functionally across hardware, software, mechanical, integration, testing, production, supply chain and project management teams to ensure seamless product development and successful delivery within time.
• Ensure compliance with relevant international safety and performance standards.
• Troubleshoot and resolve complex system issues related to system behaviour, thermal management, electromagnetic compatibility/interference (EMC/EMI), and power quality.
• Lead detailed design reviews and ensure comprehensive validation and verification coverage across system interfaces and critical performance metrics, including hardware-in-the-loop (HIL) testing where applicable and safety assessments.
• Ensure the product meets quality, cost and timeline requirements.
• Oversee the creation and maintenance of detailed technical documentation, including schematics, Bills of Materials (BOM), specifications, test protocols, validation reports, and production drawings.
• Provide mentorship to junior engineers while fostering a culture of knowledge sharing and driving continuous improvement in engineering processes and best practices.

Required Qualifications & Experience

• MTech. in Power Electronics specialization or related discipline.
• 10-15 +years of experience designing and developing power electronic systems, preferably in automotive or industrial sectors with 10kW and above ratings.
• Deep knowledge of power conversion topologies(AC/DC, DC/DC, DC/AC), magnetic component design, and switching device characteristicsEnd to end product lifecycle development experience
• Proficiency in control system theory, including PID and digital control algorithms, and implementation on embedded platforms (microcontrollers, FPGAs).
• Solid hands-on experience with industry-standard simulation and design tools such as MATLAB/Simulink, PLECS, LTspice, Altium Designer, and PCB design suites.
• Familiarity with embedded software and firmware development for power converter control (e.g., C/C++, microcontrollers, FPGA programming).
• Proven track record of successfully taking products from concept through validation, functional safety assessment, and mass production launch.
• Understanding and application of functional safety principles and standards (ISO 26262, ASIL) and systems engineering methodologies (FTA, FMEA, V-Model/System V).
• Knowledge of electric vehicle systems and high-power applications, including thermal management, safety, and EMC/EMI requirements.
• Passion for innovation, high ethical standards, and a commitment to engineering excellence and product quality.

Preferred Qualifications

• Experience working directly with automotive OEMs or Tier-1 suppliers.
• Exposure to model-based design approaches and hardware-in-the-loop (HIL) simulation environments.
• Familiarity with automotive and industrial communication protocols such as CAN, LIN, and Modbus.
• Excellent documentation skills, strong interpersonal and communication abilities, and a proven ability to collaborate effectively in multidisciplinary teams.
• Knowledge of standards such as IEC 61851, IEC 62133, CE, UL, IS standards, ISO 26262, ASIL, OCPP+ and IATF 16949.
