At Octopus Energy Trading, we’re on a mission to reshape the future of energy. As part of Octopus Energy Group, we’re creating an innovative approach to trading that will accelerate the transition to a Net Zero world. With the growth of renewables and a push toward decarbonising heating and transport, greater flexibility in the grid is essential. We are building cutting-edge technology to optimise everything from domestic EV charging to grid-scale batteries, to meet the global demand for energy flexibility.

We’re looking for passionate and unconventional thinkers to join us on this journey, bringing a diversity of experience and ideas to shape a more efficient, flexible, and sustainable energy system.

We're looking for a Trading Data Engineer (f/m/d) to join our German and Western European intraday trading team. You should have strong Python skills, know how to manage Redis cache, AWS S3 or DBT, and bring experience in the German or European power market. You'll work in a fast-paced, tech-driven environment and collaborate closely with traders and developers to turn data into real trading decisions.

What You'll Do

Build and maintain models to forecast power demand, renewable generation, and prices in the German and Western European intraday markets

Develop robust data pipelines to collect, clean and combine internal and external data (e.g. grid, weather, or market data)

Analyse market data and derive insights to optimise trading strategies

Help build tools for automated trading and market analytics

Contribute to models predicting local grid congestion and identifying flexibility opportunities

Collaborate closely with our Trading, Flexibility and Tech teams across Germany and the UK

Support the development of our forecasting and analytics frameworks across the business

What You'll Need

Excellent Python programming skills

Experience with time series data, forecasting, and machine learning (e.g. Redis cache, AWS S3, Databricks, Grafana)

Exposure to the German or European electricity market (e.g. EPEX Spot, Redispatch, TSOs)

Experience building data pipelines and automating data workflows

Ability to clearly communicate modelling approaches, including assumptions and limitations

A structured, quality-focused way of working and a desire to take ownership

Enthusiasm for accelerating the energy transition and optimising flexible power systems

Fluent German and English (both are required)
