• Experience working in data analytics, including the design and implementation of analysis tools
• Experience working with real-life timeseries data of physical systems
• Experience with data pre-processing and cleaning
• Experience working with Numpy, Pandas, Polars and other standard python toolboxes for data analysis
• Independent and driven person who can work autonomously and take initiative, but also a team player who will contribute and work well with others.
• Good communicator with a particular aptitude to convey data-driven results clearly and concisely to stakeholders

Nice to have

• Knowledge of battery and energy systems, or experience working with battery data
• Experience with AI / ML techniques or statistical data analysis tools
• Experience with SQL and other tools for data querying
• Experience working with cloud computing platforms, ideally Azure
• Experience with other programming languages (C, C++, C#, Matlab)
• Experience studying the real-world and commercial impact of data analytics
• Skilled project planner, working with competing tasks and timelines
