About the company:

We're on a mission to make a big green dent in the universe by building a truly sustainable energy system globally.

That means making power greener, smarter, and more affordable for everyone.

We put customers at the heart of everything we do: with always-fair prices, transparency and outrageous customer service.

We drive system change: with transformative tech to make renewable energy the norm and end global reliance on fossil fuels.

Octopus Energy Group is made up of 10 businesses spanning 6 countries across 3 continents, including: Octopus Energy Retail, Kraken Technologies, Octopus Energy Generation, Kraken Flex, Octopus Electric Vehicles, and the Octopus Centre for Net Zero. More on OEG @ octopusenergy.group

The Energy Markets team at Octopus Energy is responsible for making sure that we always have the electricity and gas we need to support our customer demand whilst also supporting the grid to enable the Net Zero transition.

To achieve this mission across all Octopus international regions, we have sub-teams focused on forecasting energy demand and generation, hedging and shaping our trade position, tracking and reporting the ongoing risk to Octopus, and driving the proportion of our supply directly from generators via PPA agreements.

The Engineering sub-team owns our global technical platform that supports these different processes and drives forward long-term solutions to enhance Group capabilities.

We are looking for a Data Engineer to help achieve this goal - ideally someone who is comfortable diving into different tasks to support each team using a variety of coding languages across our platform setup, who enjoys developing relationships across the company while explaining technical processes in the most appropriate way, and who keeps an eye on scalable solutions to support data growth.

This is therefore an exciting opportunity to take on a role that combines complex data engineering, visual analytics and business critical need.

Supporting different Energy Markets teams to design and build key operational and reporting pipelines across all Octopus Energy regions;

Taking responsibility for the maintenance of these critical data pipelines supporting core trading, forecasting, risk and PPA processes;

Setting up and maintaining processes for capturing, preparing and loading valuable new data into the data lake;

Designing and building dashboards that cover operational processes and reporting requirements;

Working with international teams across the Octopus Energy Group to ensure everyone shares the best possible practises and code is standardised where possible;

Taking ownership of data platform improvements that enhance the capabilities for all Energy Markets teams and drives trust in the stability of the setup;

Sharing, enhancing and upskilling team members on available tools and best practices.

What you'll need...

Strong aptitude with SQL, Python and Airflow;

Experience in kubernetes, docker, django, Spark and related monitoring tools for devops a big plus (e.g. Grafana, Prometheus);

Experience with dbt for pipeline modelling also beneficial;

Skilled at shaping needs into a solid set of requirements and designing scalable solutions to meet them;

Able to quickly understand new domain areas and visualise data effectively;

Team player excited at the idea of ownership across lots of different projects and tools;Passion for driving towards Net Zero;

Drives knowledge sharing and documentation for a more effective platform;

Open to travelling to Octopus offices across Europe and the US.

Our Data Stack:

SQL-based pipelines built with dbt on Databricks

Analysis via Python jupyter notebooks

Pyspark in Databricks workflows for heavy lifting

Streamlit and Python for dashboarding

Airflow DAGs with Python for ETL running on kubernetes and docker

Django for custom app/database development
