Security Engineer

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. 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 centres and other energy‑intensive industries. We are looking for a motivated and detail‑oriented Security Engineer to support and strengthen our security posture as we scale. In this role, you will work closely with senior security and engineering team members to help secure our infrastructure, applications, and data. This is an excellent opportunity to grow your security expertise in a fast‑paced, product‑focused environment while contributing to real‑world systems with meaningful impact.
