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 a Senior Electrical Engineer to act as the electrical authority across grid connection works, utility-scale solar PV, BESS and data centre power infrastructure, from development through commissioning and handover.

Responsibilities

  • Act as electrical SME across grid, solar, BESS, and data centre projects; produce and own electrical designs across the portfolio
  • Deliver detailed design across substations, transformers, switchgear, protection, and power distribution
  • Develop design packages from concept through detailed design: single-line diagrams, equipment specifications, protection schemes, cable sizing, and earthing/bonding
  • Support grid connection works where required (export and demand) – compliance to Grid Code, DNO/TSO/NESO, G99/G100 – and validate or produce supporting studies (fault level, load flow, protection coordination, harmonics)
  • Provide electrical input from development through handover; align design intent with procurement and construction, and resolve technical queries
  • Support and witness testing, energisation, and commissioning (substations, protection, standby/UPS); troubleshoot issues and ensure as-builts comply with approved designs
  • Support technical DD and lender advisory; provide engineering assurance across all electrical deliverables and act as escalation point for complex issues

Requirements

  • 5–10+ years of electrical engineering in power, utilities, renewables, or critical infrastructure; strong preference for substantial HV experience
  • Proven design background – able to produce and own electrical designs, not only review others' work
  • Strong infrastructure delivery experience
  • Deep understanding of electrical systems, substations, protection, and power distribution design (generation and demand)
  • Working knowledge of UK grid standards (DNO/TSO/NESO, Grid Code, G99/G100) and ability to interpret electrical studies
  • Commissioning, testing, and energisation experience
  • Critical eye for reviewing consultant and subcontractor designs; strong grasp of safety frameworks (ESQCR, EAWR, SAP/AP authorisation)

Benefits

  • Competitive salary and eligibility for equity
  • Biannual bonus scheme
  • Fully expensed tech to match your needs
  • Private health insurance
  • Breakfast and dinner allowance for office-based employees
