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 consumers, 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.

Responsibilities

In this role you will work closely within product to build the core digital infrastructure for a next-generation energy company. You will use your experience to engineer backend infrastructure that is second-to-none.

You'll be working across the back-end:

Constructing a real-time digital twin of our renewable generation and customer demand
Developing messaging interfaces with our third-party providers
Building high-volume pipelines for processing customer energy consumption
Build the backend of a world class energy app

For this role, you should be able to think on your feet and adapt to new business needs as well as take ownership of projects and drive change.

Requirements

Demonstrable excellence as a Software Engineer
Ideally 2+ years experience
Proven ability to define and build complex systems
Hands-on experience shipping highly-available production systems
Clear communication

Bonus

Experience with infrastructure as code (e.g. AWS CDK)
Experience in the Energy sector
Experience shipping consumer-facing products

Benefits

Competitive salary and an equity sign-on bonus
Biannual bonus scheme
Fully expensed tech to match your needs
Paid annual leave
Breakfast and dinner allowance for office based employees
