Senior Electrical Engineer in London

About Us:

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 $210M 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. But we’re not stopping there. We’re also building the Energy Network: a decentralised platform of smart devices to electrify our homes, shifting usage to off-peak hours and helping balance the grid. This network strengthens grid stability - a critical foundation for scaling AI data centers and other energy-intensive industries.

Purpose:

Electrical authority across grid connection works, utility-scale solar PV, BESS, and data centre power infrastructure - from development through commissioning and handover. Owns and delivers electrical design while ensuring all systems (generation, storage, demand) are designed, installed, tested, and energised safely, compliantly, and to UK requirements, providing assurance and challenge across consultants and design partners. Strong preference for candidates with substantial HV experience.

Responsibilities we will trust you with:

• 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.

Your areas of knowledge and expertise:

• 5–10+ years 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.
• Biannual bonus scheme.
• Fully expensed tech to match your needs.
• Paid annual leave.
• Breakfast and dinner allowance for office based employees.
