Finance Working Student (f/m/d)

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.

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.

• Nobel-Prize physics aimed at real customers with real problems, in production now, not someday.

• Physicists, data scientists, and engineers building side by side, turning deep science into tools the industry actually runs on.

• An international team that runs at hard problems for fun, where knowledge moves fast and so do you.

02Still unsure about why joining us?

• You'll get to build a company together with a brilliant and welcoming team on a product that has never been done before.

• From Day 1, you'll own your own topics end to end and see the direct impact of your work on how the world sees QuantumDiamonds.

• Mission: At QD, we’re driven by more than just building great products - we aim to make a lasting difference. Joining us means contributing to meaningful work that goes beyond business as usual.

• Health & fitness: With a company-sponsored Wellpass membership, you’ll have access to countless gyms, classes, and wellness offers across Germany to stay healthy and active.

• Team & culture: We believe the best ideas come when we connect outside the office. From regular off-sites to team events, you’ll be part of a collaborative and supportive environment.

• Well-being & balance: We value rest and recovery. That’s why you’ll enjoy 20 vacation days (based on a 5-Day week) plus public holidays to recharge and return inspired.

QuantumDiamonds GmbH, headquartered in Munich, Germany, develops and manufactures semiconductor inspection systems based on quantum sensing. Spun out of the Technical University of Munich in 2022, the company uses nitrogen-vacancy centers in diamond to map electrical current with micrometer precision inside advanced 2.5D and 3D chip architectures. Nine of the world's ten largest semiconductor manufacturers are engaged with QuantumDiamonds, with systems deployed across Europe, the United States, and Asia. The company is investing €152 million to build the world's first production facility for quantum sensing-based semiconductor inspection tools, supported under the European Chips Act.
