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
