Sr. Power Electronics Design Engineer

About the role

As a senior power electronics engineer, you’ll shape the architecture and delivery of high-performance converters and protection systems, driving innovation in efficiency, reliability, and manufacturability. Our integrated model of combining advanced engineering, tight supply-chain control, and exceptional service empowers you to build resilient solutions that restore reliability and control to the operators who keep the world energized.

What you'll do

• Architect, design, build and industrialize power converter hardware for use in grid and energy product applications
• Architect and model new power electronics topologies that have superior performance
• Have start to finish ownership of hardware – from specification to design, prototype, reliability validation and production
• Collaborate cross-functionally with mechanical, thermal, PCB layout, firmware, manufacturing and testing teams to validate and manufacture Ayr products
• Define and execute validation test plans including structural, thermal, and environmental testing.

Qualifications

First Principles Thinking

• Strong understanding of power converter topologies – both theory and practical design
• 5 or more years of relevant hands-on hardware experience in design and industrialization of power converter products
• Experience with high voltage power semiconductor selection (IGBTs, Si/SiC/GaN MOSFET’s, and diodes), design of gate drive and analog/digital sensing circuits
• Solid understanding of the theory and application of magnetics (inductors, transformers) and capacitors (film, ceramic and electrolytic) for high voltage and high frequency power conversion
• Knowledge of basic control theory and experience with embedded programming
• Extensive hands-on experience with advanced digital and HV circuit bring-up and troubleshooting
• Awareness of UL and CE electrical safety requirements; EMC requirements relevant to the design of power converters is a plus
• Excellent written and verbal communications in English

What we offer

• Collaborative work environment
• Challenging problems to solve
