We’re looking for an experienced and enthusiastic Data Scientist to tackle the challenge of low-carbon heating and cooling flexibility. You’ll help build next-gen optimisation models and control algorithms for heating and cooling consumer assets across the UK, Europe, and beyond.

Your work will support the commercialisation of heat flexibility in the UK and help drive the adoption of low-carbon heating in homes nationwide.

What you'll do:

• Create building-level and fleet-level heating and cooling optimisation models
• Design new & novel approaches to heat and cool homes at lower energy costs
• Work with developers to create & deliver optimisation instructions to Octopus & third-party heat pumps, air conditioners, and associated technologies
• Support the rollout of heating/cooling assets into energy flexibility markets

What you'll need:

• Experience in a relevant field like energy management, controls design, or machine learning applied to energy or complex optimisation systems
• A strong grasp of data science tools and platforms (SQL, Python, etc.)
• Solid understanding of machine learning algorithms and experience creating stochastic models
• Knowledge of UK and/or European energy markets, particularly energy flexibility
• Experience building predictive models using a range of data sources (internal and external)
• Familiarity with how heating systems behave and are controlled - especially air-to-water heat pumps and hot water systems
• A Master’s degree or PhD in a quantitative field (like Data Science, Computer Science, or Statistics) is great - but equivalent experience is equally valued
