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 we continue to develop cutting-edge technologies and sustainable energy solutions, we are looking to hire a versatile Electronics Design Engineer to help us develop the core electronics behind our plug-and-play solar products. This role focuses on designing robust, scalable electrical systems that enable safe, efficient, and reliable renewable energy hardware.
Responsibilities
- Own end-to-end electrical development, including requirements definition, specification, design execution, simulation, schematic capture, PCB layout, DFM iteration, board bring-up, system integration, and validation
