The opportunity

We’re a growing team of around a dozen, and we’re looking for a new Software Engineer to design and build the real-time server-side and embedded control systems to operate the batteries deployed by Storio.

Our storage assets unlock multiple revenue streams—energy markets, ancillary services, solar self-consumption, and beyond. Ensuring the control system’s responsiveness, accuracy, and reliability is critical. You’ll own this system, participating in every stage of its development lifecycle—from architecture and design to deployment and live production monitoring.

This role provides a chance to learn in a fast-paced environment alongside seasoned engineers and entrepreneurs. We believe in creating an environment where curiosity and knowledge-sharing thrive, enabling our team to learn from each other and move quickly.
