Working Student | Battery & Data Analytics (m/f/d)

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.

Â

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.

Â

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.
