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 centers and other energy-intensive industries.

We're now looking to establish a cutting-edge AI team. As an Applied AI Engineer, this position is ideal for someone who possesses the technical expertise of a backend engineer but is specifically interested in applied AI and how it can be used to enhance the energy experience for our customers and our internal operations. You'll be working on a variety of exciting projects, including consumer-focused features like the Energy Co-Pilot and the Speedy Onboarding process (leveraging tools such as VLM/LLM). You will also collaborate across teams to build AI tools that enhance productivity and streamline processes within Fuse.

Responsibilities

  • Design, develop and deploy AI-powered features that directly impact consumer experiences, including personalised energy recommendations and seamless onboarding via AI models (e.g. using energy bills for quick setup)
  • Build and optimise internal AI tools that will make the whole company more productive with a focus on automation and enhancing workflows
  • Collaborate with backend engineers and data scientists to integrate AI-driven features into our platforms
  • Collaborate with the trading and operations teams to ensure AI models are aligned with real-time market conditions and energy pricing
  • Improve AI models to optimise trading strategies by anticipating market shifts based on weather and demand forecasts
  • Stay up to date with the latest advancements in applied AI and machine learning and apply them to solve real-world problems within the energy space
  • Monitor the performance of AI tools and models, ensuring they are functioning efficiently and effectively

Requirements

  • Minimum 3 years of engineering experience
  • Proven experience as a Backend Engineer with a strong interest and practical experience in applied AI or machine learning
  • Strong programming skills in Python (or similar languages) with familiarity in AI/ML libraries (TensorFlow, PyTorch, etc.)
  • Experience working with large-scale models (LLMs/VLMs) and deploying AI-driven solutions into production
  • Solid understanding of cloud technologies, containerisation and building scalable AI applications
  • Ability to integrate AI/ML models into real-world applications, focusing on usability and performance
  • Strong problem-solving skills and a practical approach to implementing AI solutions in a fast-paced environment
  • Experience working with large datasets, particularly in relation to demand and supply forecasting

Bonus

  • Experience or strong interest in energy markets and trading strategies
  • Understanding of weather forecasting, energy demand patterns, and production modelling
  • Exposure to Natural Language Processing (NLP) or other related fields

Benefits

  • Competitive salary and an equity sign-on bonus
  • Biannual bonus scheme
  • Fully expensed tech to match your needs
  • Paid annual leave
  • Breakfast and dinner allowance for office based employees
