Lab Manager (Electronics Technician)

Fuse Energy is an energy startup on a mission to make energy abundant and affordable, fast. We combine first-principles thinking with cutting-edge technology to build a radically better energy system.

We’ve raised over $200M from top-tier investors including Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, 20VC, Hummingbird and Collaborative Fund, alongside strategic angels including Nico Rosberg and GPs behind Meta, Revolut, Spotify and Uber.

We’re building a fully integrated energy company: developing our own solar, batteries and other generation projects, building our own hardware, improving and developing grid infrastructure, trading power in real time, using AI across the business, and installing distributed energy in homes. By selling directly to consumers we cut out the middleman, lower costs and pass the savings on to our customers.

As Lab Manager, you will own the day-to-day running of our hardware research lab in London, where we develop and test our home energy products. This is a hands-on technician role: you will keep a fast-moving lab safe, organised and fully operational, while directly supporting the engineering team with high-quality assembly and rework.

You will be the person who makes the lab work: every tool in its place, every instrument maintained and in calibration, every prototype build supported — so engineers can focus on engineering.

Responsibilities

• Run the lab day to day: layout, organisation, labelling and housekeeping of benches, tools, components and prototypes — keeping a tidy, efficient workspace as the team and equipment grow.
• Perform SMD soldering, rework and repair on prototype boards (fine-pitch components, hot-air and iron rework, modifications to engineering instructions).
• Build cable and wire harnesses for prototypes and test rigs: cutting, crimping, connector assembly and labelling, to consistent, documented quality.
• Manage lab inventory: components, consumables and tools — tracking stock, ordering replacements before they run out, and receiving/booking in deliveries.
• Maintain lab equipment: routine care of soldering stations, power supplies and instruments, and running the equipment calibration schedule with our external calibration partners.
• Uphold lab safety: ESD discipline at every bench, PPE, safe handling and storage of lithium batteries, and keeping safety procedures and signage current.
• Support engineers with test setup builds, fixture assembly, mechanical assembly and general prototype work.
• Manage goods in/out, including packaging and shipping of hardware and batteries to partners and test houses.
