Role Overview

Job Description – Senior Power Electronics Design (P4)

Lead the end‑to‑end development and integration of advanced power electronic systems for renewable energy and industrial automation. Design system architecture, collaborate cross‑functionally, and ensure safety and performance standards. Resolve complex system‑level challenges—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

• Development and integration of power electronic systems—including AC‑DC, DC‑AC, and DC‑DC converters, inverters, renewable energy platforms, and industrial converters.
• Work through the electrical engineering lifecycle: Requirements → Architecture → Detailed Design → Prototype → Validation → Certification → Production support.
• Define system architecture, topology, requirements, and interface specifications for industrial power converters, charging platforms, high‑voltage drivetrain systems.
• Guide 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 timely delivery.
• Ensure compliance with relevant international safety and performance standards.
• Troubleshoot and resolve complex system issues related to behaviour, thermal management, electromagnetic compatibility/interference (EMC/EMI), and power quality.
• Lead detailed design reviews and ensure comprehensive validation and verification 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 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 knowledge sharing and driving continuous improvement in engineering processes and best practices.

Required Qualifications & Experience

• MTech in Power Electronics specialization or related discipline.
• 8–15+ years of experience designing and developing power electronic systems, preferably in automotive or industrial sectors with 10kW and above ratings, voltage level 400V and above.
• Deep knowledge of power conversion topologies (AC/DC, DC/DC, DC/AC), magnetic component design, and switching device characteristics.
• End‑to‑end product lifecycle development experience.
• 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 systems engineering methodologies (FTA, FMEA, V‑Model/System V).
• Knowledge of high‑power applications, including thermal management, safety, and EMC/EMI requirements.
• Passion for innovation, high ethical standards, and commitment to engineering excellence and product quality.
• Preferred Industry Background:
