About the role

As renewable energy reshapes the global power system, batteries are taking center stage. Making them safe, reliable, and bankable at scale is a defining challenge of the energy transition. At TWAICE, our software turns battery data into insights - so decisions are made with confidence, not guesswork.

We're accelerating the transition into a new energy era and we're looking for those who want to move fast with us.

As a Working Student | Battery & Data Analytics (m/f/d), you'll work hands-on alongside experienced data and engineering professionals, right at the intersection of data and real-world impact. You'll help evaluate and improve the performance and safety of battery energy storage systems used around the globe - all while getting real exposure to live operational data and the technology powering our platform.

Working hours are flexible (especially around exam periods). Ideally, you're available around 20 hours per week and able to come into our central Munich HQ on a regular basis.

Your daily business will involve

Bringing new projects onto our platform

Connecting data from operational battery storage sites to the TWAICE cloud
Building digital twins of BESS in our data model
Running data quality checks so the data our analyses rely on is solid

Analyzing real-world battery systems on demand

Making sense of power and data flows in battery energy storage systems
Running big-data analyses, using AI tools and techniques, to evaluate the performance and safety of BESS around the globe

Shaping our analytics

If you’re interested, joining customer meetings to see how your analyses make a difference

Your profile

Studying engineering, physics, data science, or a related field
Basic understanding of batteries and a passion for renewables
Confident using Python to clean, transform, and analyze data
Curious, proactive, and hands-on when solving problems
Bonus: experience with BESS, Databricks, SQL, or AWS

Don’t tick every box? Apply anyway. We know great people don’t always match every line of a job ad, and we care more about your curiosity and drive than a perfect checklist. We welcome applicants of all backgrounds and look forward to hearing from you.
