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 $170M 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 that rewards users in Energy Dollars for electrifying their 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:

The Engineering Manager will lead all engineering and design activities across the UK utility-scale solar and BESS portfolio, from early-stage development through construction and commissioning.

This role is responsible for delivering robust, bankable, and cost-optimised designs, aligned with grid requirements, planning constraints, and construction best practices. The position will act as the technical authority across projects, leading internal engineering capability and managing external consultants to ensure high-quality, repeatable, and scalable project delivery.

This position reports to the Head of Projects.

Engineering Leadership

Lead the engineering function across utility-scale solar and BESS projects in the UK
Define and implement standards, processes, and best practices
Act as technical authority across development, EPC, and operations
Build and scale internal engineering capability
Allocate resources across a multi-project pipeline

Project Delivery

Oversee engineering from development through commissioning
Ensure designs are optimised for cost, constructability, and performance
Manage external consultants to ensure quality and timely delivery
Support handover into construction and provide delivery-phase support

Technical Oversight

Oversee system design, including layouts, DC/AC, and HV infrastructure
Ensure integration of substations, grid connections, protection systems, and SCADA
Review grid requirements, connection agreements, and planning conditions
Oversee grid studies and key engineering deliverables (SLDs, layouts, specs, BoQs)
Ensure robust BOS design and material optimisation
Provide technical input into EPC strategy and procurement

Compliance & Standards

Ensure compliance with UK Grid Code, G99/G100, and relevant standards
Maintain alignment with HSE requirements and industry best practices
Stay current with evolving regulatory and technical requirements

Stakeholder Management

Act as key technical interface for internal teams, lenders, and partners
Support technical due diligence and manage independent engineers
Collaborate across development, construction, and asset management

Continuous Improvement

Drive standardisation across designs, specifications, and processes
Lead initiatives to improve efficiency, cost, and project performance
Act as escalation point for complex technical challenges
