Fuse Energy
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 $210M 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.
We're hiring Product Engineers to join a small, high-ownership product team in our London office. This isn't a role where you'll be handed fully-specced tickets, you'll own features end-to-end, from customer-facing product to internal tools, including shipping consumer-facing AI features into production, working alongside a tight team of web engineers and mobile engineers. Our infrastructure and backend are already excellent; we're looking for product engineers who bring the same bar of craft and ownership to match.
