How to Apply for Performance Analyst

at Octopus Energy

🏢 About Octopus Energy

Octopus Energy is disrupting the traditional energy market by leveraging AI, data science, and renewable energy to offer transparent, low-carbon solutions. Their innovative approach includes real-time pricing and flexible asset optimization, making them a leader in the transition to a sustainable energy future. Working here means being at the forefront of energy tech, with a strong culture of autonomy and impact.

About This Role

As a Performance Analyst, you will be the central authority on how well flexible assets (like batteries and EV chargers) are performing, directly influencing trading and optimization strategies. Your analysis will bridge data science and business decisions, ensuring the company maximizes returns while supporting renewable integration. This role is critical for refining algorithmic and human trading decisions to stay competitive in a fast-evolving market.

💡 A Day in the Life

Your day might start by checking automated performance dashboards for overnight trading results, then diving into a Python notebook to investigate a deviation in battery asset returns. You’d collaborate with traders to explain a trend you spotted, and spend the afternoon building a new CI/CD pipeline for a monitoring tool. Meetings with stakeholders would focus on translating your analysis into actionable strategy adjustments.
