Job Level

Lead

About the role

  • Define and own the technical vision, architecture, and roadmap for power electronics systems.
  • Lead the design, simulation, prototyping, and validation of high-efficiency rectifier and DC-DC converter systems (10 kW to >5 MW).
  • Drive innovation in cost-effective, scalable, and high-efficiency power conversion for electrolyzer stacks.
  • Partner with mechanical, thermal, and systems engineering to co-optimize packaging, cooling, and integration.
  • Recruit, mentor, and lead a multidisciplinary team of power electronics engineers and technicians.
  • Evaluate and manage relationships with component vendors, contract manufacturers, and external design partners.
  • Ensure compliance with relevant grid codes, EMC/EMI standards, UL, IEC, IEEE or other regulatory frameworks.
  • Work cross-functionally with Product, Manufacturing, and Operations teams to align technical goals with commercial requirements.
  • Support the development of internal and external IP strategy in power electronics and system design.
  • Guide the firmware architecture, coding standards, testing, and release processes to ensure high reliability and maintainability.
  • Ensure firmware co-development is tightly integrated with hardware design for optimal system-level performance.
  • Collaborate with systems and stack engineering to align control strategies with electrolyzer operational requirements.

Requirements

  • Master’s or Ph.D. in Electrical Engineering or a related field with a focus on power electronics.
  • 18+ years of industry experience in power electronics, including at least 5 years in leadership roles.
  • Deep understanding of AC-DC and DC-DC conversion topologies, especially in multi-kilowatt to multi-megawatt power classes.
  • Experience with medium voltage systems and safe, reliable system design in those domains.
  • Proven success delivering modular, scalable and high-efficiency electrical architectures under cost and performance constraints.
  • Hands-on experience with digital control systems, gate drivers, magnetics design and thermal management.
  • Strong familiarity with grid-connected systems, including solar PV inverters, battery energy storage or similar.
  • Excellent leadership, communication and cross-functional collaboration skills.
Benefits
  • We celebrate diversity and are committed to creating an inclusive environment for all employees.
  • Opportunity to join an organization which is accelerating the growth of green hydrogen production around the world.
  • Help deploy tangible real-word solutions to rapidly reduce greenhouse gas emissions from high carbon sectors such as energy, transport, steel, and cement production.
