Lab Technician (Physics)

Permanent employee, Full-time · München

Description

QuantumDiamonds is building the world’s first commercial quantum sensing tools for chip failure analysis. As a Physics Lab Technician, you’ll support our hardware and R&D teams in day-to-day lab operations, enabling the assembly, testing, and characterization of cutting-edge quantum sensing systems.

You’ll work hands-on with experimental setups involving lasers, optics, RF components, and diamond quantum sensors — ensuring precision, cleanliness, and reproducibility in every step. Your work helps turn prototypes into industrial-grade tools that redefine what’s possible in semiconductor testing.

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 30-strong team of physicists, engineers, and data scientists works side by side with major semiconductor manufacturers, helping them in chip debugging and accelerating their 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.

Why join Quantum Diamonds?

Picture this:

A machine that catches what others miss – in milliseconds.
Physics, data, and engineering are working hand in hand to build tools that matter.
An international team, who loves solving hard problems and where knowledge flows fast.

Still 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.
Our technology is the cutting edge of tomorrow, starting today and not in 10 years.
You will work directly with major semiconductor companies from Day 1.
You'll get virtual shares and act on behalf of the entire company, beyond just your own team.
You’ll be part of a high-growth company backed by top-tier investors.

Let’s make the invisible visible!
