Job Description
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 are looking for a Controls & Firmware Engineer to help design and implement the control architecture for our scalable thermal energy storage system. This hands-on role involves both PLC programming and embedded firmware development, giving flexibility as we evolve our platform from industrial controllers to custom microcontroller-based solutions. The engineer will also contribute to building test benches, CI/CD pipelines, and GitHub-based workflows to ensure high reliability and rapid iteration.
This position is based in Austin, TX, however an alternate location of Miami, FL is possible for the right candidate. If hired for this role, relocation to one of these sites is required. We provide relocation assistance.
