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
