Frontend Developer - Kraken Technologies

Help us use technology to make a big green dent in the universe!

Kraken powers some of the most innovative global developments in energy.

We’re a technology company focused on creating a smart, sustainable energy system. From optimising renewable generation, creating a more intelligent grid and enabling utilities to provide excellent customer experiences, our operating system for energy is transforming the industry around the world in a way that benefits everyone.

It’s a really exciting time in energy. Help us make a real impact on shaping a better, more sustainable future. 

Kraken Customer

What we do: build the most AI-driven, innovative, forward-thinking platform for energy management. From optimizing resources to delivering cost-effective, exceptional customer experiences through advanced Customer Information Systems (CIS), billing, meter data management, CRM, and AI-driven communications, Kraken is powering the next wave of innovation in the energy industry.

Why we do it: future energy will not look like energy as we know it today. We need to not just think about our future, but build for it. Now.

Energy is changing.

For years, it was an industry dominated by large suppliers using outdated systems that put profits first and customers last. Now, we’re using the latest technology and green generation to transform energy for customers, bringing the UK cheaper, greener, and fairer energy.

We enjoy the best of both worlds: backing from a £6bn business of highly experienced and talented individuals, and the dynamic environment of a start-up.

We are the only Which? recommended energy supplier for 2019, the uSwitch supplier of the year, Energy Awards supplier of the year, and UK customer experience award winner for utilities. 

You’ll be working for a company that’s fighting climate change. We’re the largest investor in solar generation in the UK, and are funding wind and anaerobic digestion. We’re helping people to use greener technology and renewable energy, all helping move the UK towards a lower carbon future.

And for big change, we need big minds.

We’re looking for someone who’s passionate about code, curious, and eager to learn. You’ll be working alongside other talented people in the tech department. You’ll solve problems with technology to make us, and the industry, smarter and better for customers.
