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 centers and other energy-intensive industries.

As a Senior HR Specialist, you'll own and improve core people operations across the employee lifecycle. You'll be the go-to person for HR operations, policy and process execution, HRIS data integrity, and employee support - bringing structure and speed to a fast-growing startup environment. You'll partner closely with leadership and hiring managers to deliver a high-trust, high-quality employee experience at scale.

Responsibilities

  • Own end-to-end HR operations across onboarding, offboarding, employee changes, documentation, and record management.
  • Be the HR operations lead, ensuring smooth execution, high accuracy, and strong employee experience across all touchpoints.
  • Own HRIS administration (data quality, workflows, reporting, audits), and continuously improve how we use systems and tools.
  • Draft, review, and manage contracts, letters, policy documentation, and HR communications, ensuring accuracy and consistency.
  • Drive HR process improvement: identify gaps, redesign workflows, implement SOPs, and standardise scalable processes.
  • Support and strengthen compliance practices (right-to-work, employment documentation, internal controls, data privacy, and local requirements as applicable).
  • Payroll coordination/ownership (depending on structure): ensure inputs are accurate (attendance, leave, changes), liaise with payroll vendors/finance, and troubleshoot issues.
  • Act as a first-line owner for employee relations and employee queries, resolving independently when possible and escalating complex matters appropriately.
  • Lead key people cycles such as performance reviews, probation confirmations, annual processes, and related documentation/training for managers.
  • Provide HR analytics and reporting (headcount, attrition, absences, compliance metrics), and turn insights into operational improvements.
  • Partner with recruiting/ops teams to support hiring operations when needed (offers, pre-boarding, background checks, ATS/HRIS handoffs).

Requirements

  • 2-5 years of experience in HR/People Operations (startup or high-growth environment strongly preferred).
  • Proven ability to own HR operations independently, manage multiple priorities, and deliver high-quality execution with minimal oversight.
  • Strong knowledge of core HR processes (employee lifecycle, documentation, HRIS, payroll coordination, performance cycles, compliance basics).
  • Excellent organisational skills and extreme attention to detail; able to build systems that scale.
  • Strong written and verbal communication skills; confident working with employees and managers across all levels.
  • Experience with HRIS/ATS tools, spreadsheets, reporting, and process documentation (SOPs, workflows, templates).
  • High discretion and sound judgement when handling confidential and sensitive information.
  • Comfortable in ambiguity; proactive mindset with a track record of improving processes rather than only running them.
  • Bonus: experience supporting multi-country teams, visas/relocation coordination, or working with external payroll/HR vendors.

Benefits

  • Competitive salary
  • Biannual bonus scheme
  • Fully expensed tech to match your needs
  • Paid annual leave
  • Deliveroo breakfast and dinner allowance
