Company Overview

Fuse Energy

London, United Kingdom

2022

Approximately 50 employees with €76 million in annualised revenue (source: welcometothejungle.com)

What They Do

Fuse Energy is a London-based energy company that began in 2022 focused on supplying cheaper electricity and building renewable generation assets. It operates two related businesses: a retail electricity supplier targeting homes with low-cost tariffs and a digital-first, app-based customer experience, and a B2B energy services arm that supports businesses, nonprofits, and municipalities with energy procurement, fixed-rate supply, and community solar solutions (source: fuseenergy.com) (source: fuseenergygroup.com). The company’s technology focus centers on solar farm development, data science for demand forecasting, and grid-market participation rather than a single hardware platform, enabling it to optimize power purchasing and supply balancing (source: welcometothejungle.com). Fuse Energy’s vertically integrated model combines solar generation with software-led customer operations to deliver cheaper, greener energy to price-sensitive residential and commercial customers (source: welcometothejungle.com).

Projects & Track Record

Fuse Energy’s project portfolio is focused on solar farm development and power-market operations rather than large, named utility-scale assets with published capacity ratings. The company has built solar farms to provide cheap renewable energy and offers community solar and energy procurement services to its customers (source: welcometothejungle.com) (source: fuseenergygroup.com). It currently supplies electricity to approximately 50,000 homes and is actively planning expansion into Ireland, Europe, and the United States (source: welcometothejungle.com). On the commercial side, Fuse Energy Group works with businesses, nonprofits, and municipalities, and is developing retail energy channel partnerships to broaden its market reach (source: fuseenergygroup.com).

Recent Developments

Fuse Energy has experienced rapid growth and significant funding milestones in recent years. The company completed a $10 million early-stage venture capital round in July 2025, followed by a $100 million late-stage round in November 2025, fueling its expansion plans (source: welcometothejungle.com). It reported €76 million in annualised revenue with 7x year-on-year growth, reflecting strong market traction and operational scaling (source: welcometothejungle.com). The company is actively expanding its footprint beyond the UK into Ireland, broader Europe, and the US markets (source: welcometothejungle.com).

Working There

Fuse Energy hires across a diverse range of roles including engineering, operations, solar development, commercial functions, and software development. Current and past job openings include Senior Backend Engineer, Mechanical Engineer, Firmware Engineer, Engineering Manager for Solar EPC, Senior Front-End Engineer, Brand Designer, Growth roles, AI Operations Manager, and Site Manager for Solar EPC (source: workable.com) (source: welcometothejungle.com). The company also recruits for commercial retail energy channel partner managers, indicating a focus on expanding business partnerships (source: fuseenergygroup.com). Fuse promotes a fast-moving startup culture characterized by "fair wages," "long hours," "high voltage," and offers stock options, reflecting a high-energy environment with growth opportunities (source: f.energy).

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 centres and other energy-intensive industries.

We're currently looking for Growth Interns to join the team at our London office in Canary Wharf. This 3 month paid internship offers an exceptional opportunity for ambitious individuals to gain valuable experience in a fast moving environment. You'll gain an insight into the growth and marketing operations of a high-performance startup, exposure to some of the key operators who were behind Revolut and gain a real working knowledge of how we grow as a company.

For effective growth, the fastest way to get you to learn about the industry and the product is through solving customer problems and queries in customer support. Alongside support, you will be involved in growth including social media, analytics, partnerships, and marketing. We are looking for hungry and aggressively ambitious high agency individuals with the aim of wanting to go on and build their own startup after Fuse. High performers will have the opportunity to fast-track the internship and join Fuse full-time.

Requirements

  • Degree from a top university (technical degree preferred)
  • Possess excellent verbal and written communication skills
  • Strong collaborating skills and the ability to work well in a team environment
  • A flexible and adaptable approach
  • Great attention to detail
  • Strong sense of initiative and the ability to work independently
  • Comfortable with working across various software applications
  • London based and authorised to work in the UK (Fuse does not sponsor visas for internships)
  • Growth and socials experience is a plus, but not necessary

Benefits

  • Competitive internship salary
  • Fully expensed tech to match your needs
  • Breakfast and dinner allowance for employees
  • Opportunities for fast progression
