Job description

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 $210M 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 and wind 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.

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
