# Quantum Sensing Engineer (NV Centers)

- **Company:** QuantumDiamonds GmbH
- **Location:** München, Germany
- **Contract:** Permanent contract
- **Skills:** Data Analysis, Python (Programming Language)
- **Published:** September 15, 2026
- **Apply:** https://www.indeed.com/viewjob?jk=585833fd7760d217

## About the Role

* 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.

## Description

* 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.
