Finance Intern

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've raised more than $210M 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 and Uber. We're building a fully integrated energy company: from developing solar, wind and battery projects to real-time power trading and distributed energy installations. By selling directly to consumers, we cut out the middleman, lower costs and pass savings on to customers.

The Role

• As a Finance Intern you'll do real work from day one, alongside a team that came from top banks, funds and startups. This is not a back-office finance team: we sit right next to the business, rolling up our sleeves across operations, deals and everything in between to help build and run the company as it scales. You'll get rare ownership and exposure for an internship, and a real opportunity to prove yourself and earn a full-time seat on the team. The internship runs as two tracks, Business Operations or Corporate Finance.

Across both tracks

• Whichever track you join, invoice reconciliation and cost optimisation are the shared foundation of the role: reconciling invoices against contracts, chasing down discrepancies, and finding cost savings and operational improvements across the business. Every intern owns this work.

Business Operations track

• The technical core of the finance function: writing the code, automations and AI that let a small team run a fast-scaling global company, and constantly raising the ceiling on what that team can do.
• Building the automations, scripts and internal tooling that strip manual work out of treasury, accounting and reporting, so the team spends its time on judgment and value added work.
• Implementing the latest AI to reconcile, report and analyse faster, and hunting down the next process ready to be rebuilt or automated away.
• Turning the reporting cycle into clean, largely self-running pipelines: actuals, P&L, balance sheet and cash flow.
• Standing up the data and systems backbone that tax, audit and compliance depend on.

Corporate Finance track

• Closer to the deals and the capital: financing, M&A and the strategic projects that decide where Fuse goes next.
• Supporting live financings across project, corporate and trading debt, from modelling to analysis and process work.
• Helping execute acquisitions end to end, from market research and modelling to diligence support and data-room coordination.
• Jumping onto special projects, the high-visibility, short-notice work where the team parachutes in to find an answer fast.
• Building and stress-testing the financial models behind transactions and new commercial opportunities.
• Supporting partnership negotiations with the analysis behind cost and revenue decisions.

Requirements

• Penultimate or final-year student, or recent graduate, in engineering, maths or another STEM discipline.
• Very strong first principles thinking
• Comfortable in a fast, ambiguous, high-intensity environment.
• Analytical, structured and proactive, someone who takes ownership and chases things down.
• A genuine interest in the track you're applying for, whether that is operations and process or deals and financing.
• Strong financial modelling and Excel skills.

Bonus:

• A prior internship in banking, investing, consulting, accounting or a startup finance team.
• For the Corporate Finance track, exposure to M&A, financing or strategy.
• For the Business Operations track, coding and process and automation.

Benefits

• Competitive internship salary
• Fully expensed tech to match your needs
• Breakfast and dinner allowance for office based employees
• The opportunity to convert to a full-time role for high performers
• A front-row seat at a fast-growing, well-funded energy company solving a problem that matters, with real ownership and high autonomy from day one alongside an exceptional, first-principles team.
