Descripción del empleo

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.

Our team

All technology is written and maintained by a multi-discipline engineering team of around 900 people globally. This includes server-side, client-side and mobile engineers working closely with UX experts copywriters and designers.

We follow a Kanban-like approach using Google docs and Asana to specify and manage work; GitHub CircleCI and Terraform Enterprise as part of an immutable‑infrastructure continuous delivery pipeline; and Loggly Sentry and CloudWatch to measure performance and monitor production.

Some of our coding conventions are open-source.

Kraken is a great place to learn work with some talented engineers and level‑up your skills.

Our technology

We use AWS heavily employing most of the Hashistack (e.g., Packer, Consul, Terraform) as part of a continuous deployment pipeline. See for example Django ELB health checks and continuous delivery.

Client-side we use React Redux and SASS; our mobile apps are built using native code or React Native.

What You’ll do

• We have lots of difficult design challenges to solve. The Spanish energy market is complicated, outdated and process‑heavy – there's an awful lot of domain modelling that we need to get right.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.
• We have difficult technical problems to solve. With the advent of smart meters well soon be processing millions of meter readings a day. We need the right technology in place to handle this smoothly as well as feeding data into a machine learning pipeline that models and predicts consumption.
• There's a great opportunity for disruption in the Spanish energy market. The big suppliers still dominate but are not exactly popular. The energy landscape is changing as we move to more dis‑aggregated forms of generation with less predictability, more dynamism and smarter technology. Octopus Energy were the first UK supplier to introduce a tracker tariff whose prices track the daily wholesale prices: be working for a company that's fighting climate change. Our parent company is the largest investor in solar generation in the UK and are 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 have

• We're looking for someone with a general interest in technology and problem‑solving; someone diligent and thoughtful. It would be helpful to have experience / expertise in the following (in rough priority order):
• Python
• Django (or equiv. web framework)
• Domain modelling
• HTTP and REST APIs
• Writing robust and fault‑tolerant software
• Celery and async processing
• Postgres
• English & Spanish

Plus experience in the following would be a bonus:

• AWS
• Terraform, Packer, Consul
• React and Redux
