Electrical Engineer - Infrastructure

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 Electrical Engineer owns the primary and secondary electrical design of utility-scale BESS and Solar PV projects within Fuse’s EPC function in the UK. You will independently produce and review design packages, coordinate the electrical interfaces with PCS suppliers, BESS OEMs, SCADA and protection systems, and mentor junior engineers. Your designs need to be safe, compliant, buildable and accepted by the DNO.

Responsibilities we will trust you with:

Primary Design

• Independently prepare and review electrical drawings and design packages for utility-scale BESS and Solar PV projects
• Develop HV/MV single-line diagrams (SLDs)
• Develop substation layouts and equipment arrangements
• Size switchgear, transformers and busbars
• Size and route cables
• Design earthing and lightning protection
• Prepare equipment specifications
• Carry out or review studies: load flow, protection co-ordination, insulation co-ordination and overvoltage

Secondary Design

• Develop protection and control schematics
• Design AC/DC auxiliary systems
• Develop protection relay configurations and interlocking logic
• Size CTs and VTs and design protection circuits
• Design metering, control and indication circuits
• Produce cable schedules, termination drawings and wiring diagrams
• Produce interface drawings and I/O schedules

Interfaces and Coordination

• Coordinate electrical design interfaces with PCS, BESS OEMs, SCADA and protection systems
• Coordinate with external consultants, OEMs and EPC contractors
• Respond to RFIs, TQs and site queries on the electrical design
• Resolve technical design issues and maintain engineering quality throughout project delivery

Quality and Compliance

• Perform internal design checks before issue
• Ensure compliance with applicable IEC, IEEE and UK standards, including DNO requirements, G99, the Grid Code and ENA Engineering Recommendations
• Meet designer duties under CDM 2015, including design risk assessments

Team Development

• Guide and mentor junior electrical engineers in design development
• Review and sign off their work to a consistent standard

• 5+ years in electrical design within power, utilities or renewable energy, with utility-scale BESS and/or Solar PV experience
• Proven ability to design independently, with hands-on primary and secondary design experience
• Strong knowledge of HV/MV substation design, protection and control, earthing and cable sizing
• Experience with load flow, protection co-ordination, insulation co-ordination and overvoltage studies
• Strong knowledge of IEC and IEEE standards and UK grid requirements (DNO, G99, Grid Code)
• Experience coordinating design interfaces with PCS, BESS OEMs, SCADA and protection systems
• Experience working with consultants, OEMs and EPC contractors
• Experience mentoring or guiding junior engineers
• Strong written and verbal communication

Nice to have

• Chartered or Incorporated status (CEng or IEng, MIET)
• SCADA and plant control design experience
• Proficiency in design and study tools (AutoCAD, ETAP, DIgSILENT PowerFactory)
• Experience with DNO or IDNO design acceptance
• Experience supporting commissioning and energisation

• 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
