Exowatt develops modular P3 “rocks-in-a-box” solar thermal batteries that aim to supply AI data centers with continuous power at roughly $0.01 per kWh.
Exowatt is revolutionizing the energy landscape for the AI era with our groundbreaking P3 system that captures solar energy, stores it as heat, and generates electricity on demand. 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. We're hiring a Senior/Staff Product Certification Engineer to own product compliance and safety across our hardware portfolio. You'll be the primary bridge between our engineering teams and the global safety agencies (UL, Intertek, CSA) that gate our path to market — ensuring our energy storage systems, power electronics, and supporting technologies meet the highest safety and performance standards before they're deployed at customer sites. This is a high-leverage role. The pace of certification work directly determines how fast we can deliver power to customers, and how confidently we can deploy at scale. This role is based in our Austin, TX facility. Relocation is required, and relocation assistance will be provided if necessary.
