Your role in the team
- zerothird GmbH is seeking a highly skilled Quantum Optics Engineer to join our innovative team in Vienna, focusing on the development, characterization, and operation of entanglement-based Quantum Key Distribution (eQKD) systems.
- This role is centered on, but not limited to, hands-on experimental work in the lab, contributing to the design, optimization, and stabilization of optical and opto-electronic subsystems.
- The position also interfaces closely with software and systems engineers to ensure robust, scalable, and performant quantum communication systems.
- Experimental Quantum Optics Development: Design, build, align, and operate optical setups for polarization-entangled photon sources and entanglement-based QKD systems, including free-space and fiber-based implementations.
- System Characterization & Optimization: Perform detailed measurements of source brightness, entanglement quality, loss, timing, and stability; analyze results and iteratively improve system performance and robustness.
- Laboratory Operations: Take ownership of laboratory experiments, including optical alignment, calibration of detectors and electronics, troubleshooting of experimental issues, and documentation of setups and procedures.
- Automation & Control: Develop and maintain experiment control, data acquisition, and analysis software (e.g., for measurements, calibration routines, and long-term stability tests).
- Cross-Disciplinary Collaboration: Work closely with software, electronics, and systems engineers to integrate optical subsystems into full QKD nodes and network deployments.
- Technology Evolution: Contribute to the exploration and prototyping of next-generation components and concepts, including improvements to entangled photon sources and optical subsystems.
