We have over thirty manufacturing and assembly plants worldwide servicing over 10,000 customers in more than 100 countries. Worldwide headquarters are located in Reading, PA, USA with regional headquarters in Europe and Asia. We complement our extensive line of Motive Power and Energy Systems with a full range of integrated services and systems. With sales and service locations throughout the world, and over 100 years of battery experience, EnerSys is the power/full solution for stored DC power products.

Job Purpose

ThePower Electronics Leadwill take technical leadership of the design, development, and industrialization of high‑power AC/DC conversion systems, including megawatt‑scale Power Conversion Systems (PCS).

This role requires deep expertise in power electronics, advanced AC/DC topologies, liquid‑cooled systems, and the ability to manage multidisciplinary engineering teams.

The leader will drive innovation, ensure product reliability, and support the deployment of robust power conversion solutions for demanding industrial applications.

Essential Duties and Responsibilities

• Lead engineering activities for MW‑class PCS, including topology selection, control strategies, grid‑interface functions, and protection systems.
• Define system architectures combining power modules, control electronics, thermal systems, and mechanical integration.
• Supervise the design and validation of liquid‑cooling systems (cold plates, pumps, coolant loops, heat exchangers) for high‑density power converters.
• Conduct advanced simulations (electrical, thermal, EMC) and guide the team in implementing best‑in‑class design practices.
• Ensure compliance with relevant standards (UL, IEC, CE, EMC, grid‑connection standards).
• Coordinate cross‑functional teams (mechanical, software, industrialization, quality) throughout the product lifecycle.
• Manage supplier relationships for semiconductors (SiC/GaN), magnetics, capacitors, and thermal components.
• Lead technical reviews, FMEA/DFMEA, and reliability assessments.
• Support customer projects, commissioning, and troubleshooting of deployed systems.
• Mentor and develop engineering talent within the team.

Required Qualifications

• Master’s degree or PhD in Electrical Engineering, Power Electronics, or a related field.
• Good level ofFrenchandEnglish
• 8+ years of experience in AC/DC converter design for high‑power industrial applications.
• Strong expertise in semiconductor technologies (IGBT, SiC MOSFET, GaN), magnetics, and digital control.
• Proven experience with liquid‑cooled power modules and thermal management.
• Familiarity with grid‑connected power electronics (harmonics, EMC, protection, control loops).
• Experience managing engineering teams and complex technical programs.
• Proficiency with simulation tools such as PLECS, MATLAB/Simulink, COMSOL, LTspice.

Preferred Qualifications

• Experience in industrial electrification, heavy‑duty charging, renewable integration, or microgrid power conversion.
• Knowledge of communication protocols (CAN, Modbus, Ethernet, …).
• Background in certification processes for industrial power equipment.
• Experience with commissioning and field support for large‑scale converters.

What This Role Offers

• A strategic leadership position in a high‑growth industrial power electronics sector.
• The opportunity to shape next‑generation MW‑scale PCS and high‑power charging technologies.
• A highly technical environment with strong innovation potential.
• Direct impact on industrial electrification and energy transition initiatives.
