**Workplace:** on_site

## 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 $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 are looking for a hands-on and technically skilled 2nd Line IT Engineer with strong Network Engineering experience to keep Fuse running at full speed. You will own the day-to-day technical environment across two office locations, ensuring our networks, infrastructure and end-user hardware operate reliably so we can focus on building the future of energy. The ideal candidate is a problem-solver who thrives in a fast-paced environment, and is comfortable owning issues end-to-end, from conferencing hardware to a firewall policy change.
