High Voltage Technician

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.

We're hiring an HV Technician to support utility-scale solar PV, BESS, and critical infrastructure (including data centre power) projects across Spain, from installation through commissioning and handover.

• Working knowledge of Spanish grid standards and requirements (REE, distribuidoras) is a plus
• Strong understanding of electrical safety frameworks and site safety practices
• Relevant HV authorisations/qualifications (or ability to obtain them)
• Fluent Spanish required; English language skills are a plus
• Willingness to travel to project sites across Spain

Benefits
