Role
Who you are
- You’re degree level educated in Computer Science or a related discipline or you’re able to demonstrate equivalent workplace experience
- You have 2+ years of relevant experience in data science, quantitative analysis, quantitative research, or a closely related role
- You’re experienced in writing clean, maintainable, and production-ready Python code
- You have experience developing, evaluating, and deploying machine learning models, with an understanding of the strengths and limitations of different approaches
- You have solid knowledge of applied statistics, probability, and experimental best practices, with an understanding of common pitfalls and their impact on decision-making
- You’re familiar with optimisation techniques and their application to real-world decision-making problems
- You have experience working on quantitative decision-making systems such as trading, optimisation, forecasting, or automated control systems. Experience in energy markets or battery optimisation is advantageous but not required
What the job involves
- As a Data Scientist in the Nimbus Trade Optimiser team at Arenko, you will play a key role in shaping and evolving our algorithmic physical power trading strategies. Nimbus Trade is an algorithmic trading product used by traders and asset owners to automate the trading of grid-scale batteries and flexible assets
- This role focuses on the data, optimisation, and strategy logic embedded in a production trading system, directly influencing how assets are traded in live energy markets. You will work at the intersection of data science, optimisation, and energy markets, helping to design the next generation of our optimiser and discover new trading and operational strategies in a rapidly changing energy landscape
- Batteries and flexibility are fundamental to operating electricity grids with high levels of intermittent renewable generation. In this role, you will focus on understanding how our optimiser behaves in real market conditions, identifying opportunities to improve performance, robustness, and value capture
- You will explore large and complex datasets produced by energy markets, trading systems, and simulations, and translate insights into improvements to optimiser logic, strategy design, and decision-making frameworks
- You will work closely with engineers and traders to ensure data-driven ideas are implemented, tested, and evaluated in real market conditions. Your work will directly support trading outcomes for a market-leading client base operating battery and flexibility assets
- Analyse market, trading, and operational data to identify opportunities to improve trading performance, optimiser behaviour, and value capture
- Design, develop, and evaluate machine learning, statistical, and optimisation-based solutions to support trading and operational decision-making
- Develop and test new trading and operational strategies using historical analysis, simulation, and experimentation techniques
- Contribute to the design and evolution of optimiser objectives, constraints, and decision-making frameworks
- Collaborate closely with engineers and traders to translate analytical insights into production-ready improvements
- Build tools, analyses, and workflows that improve visibility into optimiser performance and reduce reliance on manual processes
Application process

Our take
In 2020, renewable energy was the only energy source for which demand increased and it is expected that renewables will account for 90% of capacity increases over the next two years. Arenko Group aims to modernise the infrastructure that ensures this capacity can be optimised.
The company provides software solutions that allow energy operators to increase their grids' flexibility and secure their energy supply more efficiently. Through their AI-powered software system, Arenko supports battery asset owners and operators to optimise their energy storage by allowing them to automatically buy and sell electricity on the grid ensuring they maximise revenue across multiple power and energy markets at the same time.
Arenko currently works with the battery and grid operators across the UK and are part of the National Grid ESO’s Technology Advisory Council, along with the likes of Transport for London and Octopus Energy. With a focus on creating a faster path to net zero and a more resilient energy grid, Arenko aims to become a global leader in this space.
