Founded in 2023 and backed by leading investors including Andreessen Horowitz, Sam Altman, and Felicis, we're committed to providing clean, modular, and scalable power that meets the rapidly growing demands of AI infrastructure. Our mission is to make sustainable renewable energy always available and almost free, enabling technological advancement while protecting our planet.\nWe are looking for a Lead Power Electronics Engineer to lead development of Exowatt’s next-generation MW-class multi-port power conversion solution. This person will own system architecture, product and engineering requirements, partner evaluation, development oversight, validation, and certification readiness for a high-power solution using advanced technologies such as SiC, GaN, and/or Solid State Transformer architectures.\nThis is a senior technical role for someone who has designed, developed, or brought up power conversion systems at the hundreds-of-kW to MW scale. The ideal candidate has practical experience with high-power converter design, grid-interactive systems, controls integration, protection, thermal and mechanical design, EMI/EMC, safety, and certification.\nThe person in this role will work closely with product, systems, controls, firmware, mechanical, thermal, manufacturing, supply chain, and external development partners to bring a robust MW-level multi-port solution to certification readiness by Q4 2027.\nThis position is based in Miami, FL. If selected, relocation to Miami, FL is required.
