Job Specifications
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 $100M 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 customers, 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 for a hands-on and detail-driven Electrical Engineering Intern to join our team onsite in London. You'll be working closely with some of Europe's best operators who have joined us from the likes of Tesla and SpaceX, helping to test and build an all-in-one solar and storage product.
This role is ideal for someone who can deal well with ambiguity, reason from first-principles and demonstrate engineering rigour. You should be comfortable working in a lab and have experience testing and debugging your own products.
Responsibilities
Set up and run circuit tests, record results and identify ways to improve performance
Measure switching waveforms, characterise circuits and test their limits
Debug designs, propose fixes and take ownership of testing and PCB validation
Support power converter, battery management and electronic design projects
Assist with cost optimisation, automated test setups and production ramp-up
Contribute to continuous improvements and future product iterations
Requirements
Degree in Electrical Engineering, Electronics, Mechatronics or a related field
Strong hands-on experience - you've built, tested or debugged your own projects
Knowledge of power electronics, converter topologies, switching devices (SiC, GaN) and waveforms
Confident using lab equipment like oscilloscopes, probes and high voltage test benches
Safety-conscious and curious - you like understanding how things work (and how to make them better)
Bonus
Experience designing or testing a solar converter, grid inverter or power converter
Exposure to PCB design and debugging
Interest in battery management systems or renewable energy technologies
Benefits
Competitive internship salary
Fully expensed tech to match your needs
Breakfast and dinner allowance for office based employees
Opportunities for fast progression
