Technical Product Lead

Fuse Energy is a forward-thinking renewable energy startup dedicated to transforming the energy landscape. We’re on a mission to deliver a terawatt of renewable energy - fast. Backed by top-tier investors (Accel, Balderton, Lowercarbon), we combine cutting-edge technology with first-principles thinking to create a radically better energy system.

We’re looking for exceptional, technical problem solvers to join us as we continue to scale. This is a uniquely hybrid role that sits at the intersection of software, systems engineering, strategy and operations. This is not a back-office ops role. You’ll be building real-world infrastructure, pricing new energy products, integrating trading systems and scaling our platform across markets.

Responsibilities

• Design, prototype, and scale new energy products, from idea to delivery, using tools like Python and SQL.
• Model physical and financial energy systems: optimise capacity and build business logic for everything from trading to tariffs.
• Work closely with engineers and operators to build and launch real-world systems across our energy stack - solar, storage, EVs, hydrogen and beyond.
• Deep dive into markets and regulations to break into new geographies - scoping feasibility, operational constraints and cost models.
• Own end-to-end delivery of critical projects: from writing Python scripts to running simulations, negotiating with suppliers and iterating based on real-world feedback.

• You’re technical - a strong background in engineering, physics, maths or similar from a top university.
• You’re a builder - excited by ambiguity, obsessed with progress and happiest when getting stuck into a hard problem.
• You get systems - and can reason across hardware, software, regulation and operations.
• You’re entrepreneurial - with strong product intuition and a high sense of ownership.
• You care about the mission - and want to spend your time working on real, meaningful problems in the energy space.

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