Job description

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 $100M 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.

• Build and maintain responsive, performant web applications using React, TypeScript, Next.js, and modern front-end practices
• Collaborate with backend engineers to implement APIs and ensure smooth data integration
• Work closely with product and design teams to deliver intuitive, user-friendly experiences
• Participate in prototyping and experimentation to test and validate new features
• Dig into data, validate ideas, and help define the product roadmap
• Contribute to our broader product direction and help shape the future of clean energy tech
