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 in our Finance Team, you’ll be involved in day-to-day operations, take on real ownership, and see firsthand how decisions shape the company. You won’t just observe; you'll play an active role in keeping the business running and growing.
This position has the potential to become a permanent role upon graduation.
Working hours and days are flexible (particularly around exams). You should be available for at least 15 hours per week and be able to come into our central Munich HQ once per week - though you're welcome to come in daily if you'd like.
Your daily business will involve
- Take the lead on parts of Accounts Payable through Spendesk for our German and US entities - checking invoices for correctness under HGB/US-GAAP, applying the correct accounts and cost centers, and preparing payments for approvals.
