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.

Responsibilities

You will manage the networks, on-site infrastructure and hardware that our team relies on every day and will work closely with the wider IT and engineering teams to design, deploy, secure and support our environment.

  • Work across our London based offices, external sites and our growing cloud presence
  • Administer, manage and update our office networks, firewalls and internet related infrastructure.
  • Build and maintain our on-premise servers and storage infrastructure
  • Own all office hardware problems: laptops, meeting room AV and printers
  • Provide 2nd line support and assist in onboard/offboard staff
  • Proven 2nd line IT experience with network engineering responsibilities
  • Cisco networking experience with a CCNA (or equivalent)
  • Hands-on experience configuring and managing FortiGate firewalls
  • Strong grasp of core networking (TCP/IP, routing, switching, VLANs, VPNs, Wi-Fi)
  • Confident supporting on-site servers and end-user hardware (Windows/macOS)

Desirable

  • Experience supporting IT in a SaaS environment
  • AWS cloud experience
  • Additional networking or security certifications (e.g. CCNP, Fortinet NSE)
  • Biannual bonus scheme
  • Fully expensed tech to match your needs
  • Paid annual leave
  • Breakfast and dinner allowance for office based employees
