About the Company

QuantumDiamonds, headquartered in Munich, Germany, is at the forefront of developing semiconductor inspection systems based on quantum sensing. Founded in 2022 as a spin-off of TU Munich, we leverage nitrogen-vacancy centers in diamond to map electrical current with micrometer precision inside advanced 2.5D and 3D chip architectures. Our systems are deployed globally, and we are backed by top-tier investors and strategic public programs.

Responsibilities

• Own the end-to-end NV sensing chain of the QDM, from laser excitation and diamond sensor through microwave spin control and bias field to fluorescence collection and camera readout.
• Develop and benchmark measurement protocols (e.g., ODMR variants, pulsed sequences, lock-in and referencing schemes) that improve sensitivity, speed, and robustness.
• Prototype hardware improvements across microwave delivery, photon collection, bias magnetics, and timing, and validate every concept hands-on in the lab.
• Steer our diamond sensor R&D, providing technical direction to our diamond material/process experts and driving recipe optimizations for NV-layer epitaxy, irradiation and annealing, surface preparation, and optical coatings towards our system-level performance goals.
• Define diamond specifications, characterize new material generations (NV density, contrast, coherence, strain), and correlate material parameters with system performance.
• Collaborate across hardware and software, document your findings, and hand over validated technologies to our Product Development Team.

Requirements

• A degree in Physics, Quantum Engineering, Electrical Engineering, Materials Science, or a related field, typically with a PhD or equivalent hands-on experience with NV centers or a closely related quantum sensing platform.
• Deep understanding of NV physics: ODMR, optical spin polarization and readout, and magnetometry protocols, and how they set practical sensitivity limits.
• Systems-level thinking and solid working knowledge of the optics and electronics around a quantum sensing experiment: you troubleshoot across domain boundaries down to the root cause.
• A working understanding of how diamond growth, doping, irradiation, annealing, and coatings shape NV properties, or the drive to build this expertise fast.
• The ability to steer recipe development with partners: defining specifications, designing characterization campaigns, and turning results into process improvements.
• Confident use of Python for experiment control, automation, and data analysis.
• Strong communication and documentation skills, comfortable in a fast-paced, multidisciplinary team. The working language is English.

Nice to Have

• Experience with widefield NV magnetometry or camera-based quantum imaging.
• Familiarity with semiconductor failure analysis, inspection, or metrology.
• Hands-on experience with CVD diamond growth, irradiation and annealing, or thin-film optical coatings.
