Test Engineer - Solar Simulator
Exowatt — Tracked from its lever job board
About the role
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 Test Engineer to own day-to-day operation of the solar simulator and lead the characterization and validation testing that feeds directly into our product development. This is a hands-on role for someone who likes working with real hardware, high-flux optics, and high-temperature systems — and who gets energized by the fact that the data they generate actually drives design decisions.
This position is based in Miami, FL. If selected, relocation to Miami, FL is required. Exowatt provides relocation assistance.
