Finance Working Student (f/m/d)

Description We are looking for a diligent performer, because clean books are the foundation of everything that follows. Join the CEO Office at QuantumDiamonds (QD) and become the backbone of our finance organisation. You will own your processes end-to-end and run them independently, from invoice intake to payment and the handover to our tax advisors. As a Working Student in Finance, you will keep our books clean, our invoices and expenses on track and our records audit-ready, handling day-to-day accounting with a strong focus on invoice processing, expense handling and bookkeeping. At the same time, you will help us improve and automate our finance processes as we scale from a fast-growing deep-tech company to industrial production. Who we are Founded in 2022 as a spin-off of TU Munich, QD leverages quantum sensors to rapidly capture three-dimensional current maps within multi-layer chips. Our strong, international team of over 70, including physicists, engineers, data scientists, and other experts, works side by side with major semiconductor manufacturers, supporting chip debugging and accelerating yield analysis. Backed by top-tier deep tech investors, semiconductor experts, and strategic public programs, we have ensured long-term stability, shifting from breakthrough to scale - and shaping the next chapter in chip testing.
