What the job involves

We're hiring a Senior/Lead Backend Engineer to build the core digital infrastructure for a next-generation energy company. You'll work closely with product across the full back-end and engineer backend systems that are second to none

Working on one of the core data challenges in energy: settlement data can arrive months after delivery, requiring systems that support continuous recalculation as new data becomes available

Building and extending our trading and hedging systems, covering forward markets, portfolio optimisation, and reconciliation against exchanges we trade on directly

Our take

Traditional energy companies often prioritise profit over sustainability, leading to high prices and reliance on fossil fuels. Fuse Energy aims to disrupt the energy market by offering lower prices and cleaner energy options.

It does this by building solar farms that ensure access to cheap, renewable energy. Its data science team forecasts energy demand and buys additional power from gas and electricity markets, providing a mix of renewable and traditional sources.

With €76M in annualised revenue and 7x year-on-year growth, it now supplies 50,000 homes and plans to expand into Ireland, Europe, and the US. Backed by new AI features and with investments into clean energy, Fuse is truly shaping up to redefine the future of home energy.
