Job description

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 create the technology that redefines utilities and unlocks a new energy system of the future. By optimising renewable generation, building a more intelligent grid, and empowering utilities to deliver an exceptional customer experience, our operating system is transforming the industry worldwide.

It’s an incredibly exciting time to work in energy. Join us on our mission to improve the lives of ONE BILLION humans within the decade and shape a cleaner, better future for everyone.

Kraken Utilities

Our tech platform ‘Kraken’ is already licensed to support 90 million customer accounts globally, and we aim to serve 100 million by 2027. Kraken is the most AI-driven, innovative, forward-thinking platform for energy management. From optimising resources to delivering cost-effective, exceptional customer experiences through advanced Customer Information Systems (CIS), billing, meter data management, CRM, and AI-driven communications.

We’re now charging the Kraken platform to other utility industries (Water and Broadband) and have created a new team called - Kraken Utilities. Over the last 3 years we have built this team from scratch to re-architect, design, and develop our Kraken software platform to solve complex industry wide problems within the water and broadband sectors (such as customer experience & water leak detection).

The Kraken Utilities team is in a very exciting growth phase, and has already signed six key clients: Severn Trent, Leep, Portsmouth Water, Essential Energy, TalkTalk, and Cuckoo. We are currently 120+ people strong globally.

What you’ll do:

• We have lots of difficult design challenges to solve. The UK utilities market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right. Strong attention to detail is essential.

• Help build and scale the Kraken utilities team by embedding an engineering, problem solving, and customer-first culture.

• Architect & develop new components of the Kraken platform to serve other utilities.

• We have a lot of challenging problems to solve as we work to improve the utilities industry. You will help find the right technology to build complex lifecycle journeys and payment flows, deal with hard industry problems, and support the processing of millions of readings.

• There's a great opportunity for disruption in the UK water and broadband markets. The landscape is changing as we move to more dis-aggregated forms of generation, with less predictability, more dynamism and smarter technology.

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

What you'll need:

We're looking for someone with a general interest in technology and problem-solving; someone diligent and thoughtful. Experience with the following:

• Python

• Django (or equiv. web framework)

• Domain modelling

• HTTP and REST APIs

• Writing robust and fault-tolerant software

• Celery and async processing

• Postgres

Plus experience in the following would be a bonus:

• AWS

• Terraform, Packer, Consul

• React and Redux

At Kraken, we're creating a team of genuine, honest, empathetic people. Our people are our strongest asset and the unique skills and perspectives people bring to the team are the driving force of our success.
