Electrical Engineer Spain

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 electrical engineering for Fuse’s EPC function in Spain, from design through testing, commissioning and energisation, across our infrastructure projects (Solar PV, BESS, Distribution Network, Wind, Gas-Peaker and Data Centres). You are the technical authority for HV and MV systems and lead the team that designs, builds, tests and energises them. You know how to work with Red Eléctrica (REE) and the distribution companies, so every system we deliver is safe, compliant and accepted by the grid operator.

Electrical Leadership, Design to Energisation

• →Lead all electrical engineering for the EPC function, from early design through construction, commissioning and energisation
• →Act as the HV/MV subject matter expert across all projects, covering substations, grid connections, transformers, switchgear, protection systems and cable networks
• →Set electrical design standards and make sure they are applied consistently across the portfolio
• →Review and approve electrical designs from internal engineers, design partners and consultants
• →Challenge designs to drive safe, compliant and cost-effective solutions

Grid Access, Connection and Compliance

• →Lead technical review of access and connection permits, connection conditions and compliance requirements
• →Ensure adherence to the Reglamento de Alta Tensión (RD 337/2014 and ITCs), REBT where applicable, REE operating procedures, distributor technical standards and the technical connection requirements for generation and storage
• →Manage inspections, OCA verifications and administrative sign-offs, and close out findings
• →Oversee the technical records and documentation required for authorisation, commissioning and handover of connection assets
• →Act as the technical interface with REE, distribution companies and third-party developers sharing connection infrastructure

Grid Studies and Technical Standards

• →Oversee and validate grid studies: short-circuit levels, load flow, protection coordination, harmonics and power quality
• →Own the technical compliance case for BESS and generation, including voltage and frequency response, reactive power capability and grid code testing
• →Review and challenge protection, control and SCADA architecture across sites

Construction, Testing and Commissioning

• →Lead HV and MV installation oversight, testing, commissioning and energisation (puesta en tensión)
• →Witness and sign off key testing: substations, protection systems and grid connection works
• →Lead energisation planning and execution
• →Troubleshoot electrical issues during construction and early operation
• →Ensure as-built systems comply with approved designs and grid requirements

Delivery and Stakeholders

• →Respond to RFIs, TQs and design clarifications, and align design, procurement and construction
• →Support handover to Asset Management
• →Support technical due diligence and lender technical advisor requirements
• →Work closely with Development, Construction and Asset Management teams
• →Act as escalation point for complex electrical technical issues

• 5 to 10+ years in HV/MV electrical engineering within power, utilities, distribution or renewable energy
• Hands-on BESS experience (design, grid compliance, commissioning or energisation)
• Deep experience of grid connection in Spain: substations, protection systems, cable networks and working with REE and distribution companies
• Strong knowledge of Spanish grid access and connection processes and technical requirements for generation and storage
• Experience reviewing grid studies (load flow, short circuit, protection coordination, power quality)
• Hands-on HV commissioning, testing and energisation experience
• Experience leading and developing engineers and commissioning teams
• Ability to challenge EPC and consultant designs with evidence
• Strong command of Spanish electrical safety regulations and compliance frameworks
• Engineering degree (Ingeniero Industrial or Ingeniero Técnico Industrial) with professional registration (colegiación) and authority to sign projects
• Fluent Spanish and professional English
