Java Developer jobs in United Kingdom

As a Software Engineer on the Industry Platform team you will be responsible for building, and supporting integration solutions that connect internal and external applications. You’ll work closely with the rest of the team and others inside and outside the Technology department to deliver scalable APIs, services, and automation workflows that enable seamless interoperability.

Some days are more collaborative, others are heads-down and focused—whether you're writing clean, scalable code, reviewing pull requests, or exploring ways to improve performance and reliability.

Ecotricity is Britain's greenest energy company. When we started back in 1995, we were the first company in the world to provide a new kind of electricity - the green kind.

Our mission was, and remains, to change the way energy is made and used in Britain - by replacing fossil fuels with clean, renewable energy.

We don't just supply green energy, we use the money from our customers' bills to make it ourselves too - we build windmills, sun parks and green gasmills in Britain. We call this turning 'bills into mills'. Some of our biggest achievements to date include building Britain's first megawatt windmill and the country's first grid-scale sun park, as well as building our first green gasmill, generating 100% green gas from a source that we will never run out of grass.

We don't just focus on energy though- we built the Electric Highway, Britain's leading network of electric vehicle charging points; we helped Forest Green Rovers become the greenest football club in the world; andwe launched Britain's greenest mobile phone service, Ecotalk, where they use the money from their customers' bills to protect and regenerate Britain's lost rainforests.

Ecotricity is an equal opportunities employer and is committed to providing equality for all.
