Engineering Manager - Solar EPC

Job Description

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.
