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.

Our flagship product, the Exowatt P3, captures solar energy as heat, stores it in a long-duration thermal battery, and converts it to electricity whenever it’s needed - no fossil backup required. We’re building the energy infrastructure that lets AI, and the industries built on it, keep scaling sustainably.

As a Senior HR Business Partner at Exowatt, you will serve as a strategic partner to leaders across our engineering and operations teams. This is a 6-month contract role to start, based in Austin and reporting to the Head of People & Talent. You’ll help shape and execute people strategies that enable scale, strengthen leadership, and drive high performance as we grow from breakthrough technology into full-scale manufacturing and deployment.

Partnering closely with managers and senior leaders, you’ll provide counsel on organizational design, performance management, talent planning, and employee relations while balancing near-term priorities with long-term organizational health and cultural integrity. You’ll use data-driven insights and sound judgment to identify trends, influence decisions, and drive high-impact initiatives that elevate the employee experience and strengthen manager capability.
