Fuse Energy

Infrastructure Design Engineer

TLDR

Optimise solar, BESS, wind, gas-peak and data centre projects from early development through construction handover.

Fuse Energy is an energy startup on a mission to make energy abundant and affordable, fast. We combine first-principles thinking with cutting-edge technology to build a radically better energy system.

We’ve raised over $200M from top-tier investors including Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, 20VC, Hummingbird and Collaborative Fund, alongside strategic angels including Nico Rosberg and GPs behind Meta, Revolut, Spotify and Uber.

We’re building a fully integrated energy company: developing our own solar, batteries and other generation projects, building our own hardware, improving and developing grid infrastructure, trading power in real time, using AI across the business, and installing distributed energy in homes. By selling directly to consumers we cut out the middleman, lower costs and pass the savings on to our customers.

The Design Engineer will lead the design and optimisation of our infrastructure projects (Solar, BESS, Wind, Gas-Peak, Data Centres) across the globe (UK, Ireland, Spain, USA, Australia), from early-stage development through to construction handover.

  • 3 to 6+ years of project design experience, ideally on solar, BESS, wind, gas or data centre projects
  • Experience producing technical drawings, layouts and engineering documentation using standard design tools (for example AutoCAD, PVsyst or equivalents)
