Description

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.

The Design Engineer will lead the design and optimisation of our infrastructure projects (Solar, BESS, Wind, Gas-Peak, Data Centres) across the globe (UK, Ireland, Spain, USA, Australia), from early-stage development through to construction handover.

• Supporting site feasibility, planning submissions and technical due diligence on new projects and acquisitions
• Supporting grid connection design and reviewing grid studies with external consultants, in line with local requirements
• Producing bills of quantities and giving technical input to procurement
• Handing over complete, de-risked design packages to EPC teams, and feeding construction feedback back into future designs
• Driving standardisation of designs, templates and processes across projects and markets

Requirements

• A degree or equivalent experience in engineering (electrical, mechanical, civil, renewable energy or a related field)
• 3 to 6+ years of project design experience, ideally on solar, BESS, wind, gas or data centre projects
• Experience producing technical drawings, layouts and engineering documentation using standard design tools (for example AutoCAD, PVsyst or equivalents)
• Knowledge of grid connection requirements in one of our markets
• Experience working with EPC contractors
• Strong analytical skills, with the ability to optimise a design for both performance and cost
• Clear communication with engineers, contractors and non-technical colleagues
• Curiosity and willingness to learn new technologies and markets quickly

Benefits

• Competitive salary and eligibility for equity
• Biannual bonus scheme
• Fully expensed tech to match your needs
• Private health insurance
• Breakfast and dinner allowance for office-based employees

As we hire globally, benefits vary by location.
