Fuse Energy is a forward-thinking renewable energy startup on a mission to deliver a terawatt of renewable energy - fast. We're combining first-principles thinking with cutting-edge technology to build a radically better energy system. We raised $170M from top-tier investors including Multicoin, Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, Box Group and strategic angels like Nico Rosberg, the Co-Founder of Solana and GPs behind Meta, Revolut, Spotify, Uber and more.
We’re creating a fully integrated energy company: from developing solar, wind and hydrogen projects to real-time power trading and distributed energy installations. By selling directly to consumers, we cut out the middleman, lower costs and pass on savings to customers.
But we’re not stopping there. We’re also building the Energy Network: a decentralised platform of smart devices that rewards users in Energy Dollars for electrifying their homes, shifting usage to off-peak hours, and helping balance the grid. This network strengthens grid stability - a critical foundation for scaling AI data centers and other energy-intensive industries.
As the Head of Engineering (Expansion) at Fuse Energy, you will lead the technical strategy and execution for launching our app into new international markets. Your mission is to extend the capabilities of our core systems—adapting them to new geographies, regulatory frameworks, and grid architectures—without compromising performance, reliability, or speed of innovation.
This role is both strategic and hands-on. You’ll work closely with product, operations, legal, and regulatory teams to build scalable and flexible systems that support rapid expansion. You’ll also lead a team of engineers dedicated to developing market-specific features and integrations, ensuring Fuse Energy delivers a consistent and seamless experience to customers around the world.
