Become Part of our Team

Security and sovereignty of information are granted today by complex algorithm-based cryptography. The rise of quantum computing will challenge our state-of-the art, mathematical based encryption technologies. We develop and deliver quantum key distribution (QKD) systems based on entangled photons sources to tackle quantum challenges with quantum technologies. This allows the implementation of cyber security solutions based on physical laws. Quantum Optics Jena covers the whole process chain from entangled photons sources, quantum state analyzers to quantum key-generation and -management systems. We offer solutions for fiber-based networks as well as payloads and sub-systems for future QKD-satellite networks and constellations. We enable a quantum added value to our customers and partners.  

As a start-up, we offer manifold development opportunities, flat hierarchies, challenging development projects and the possibility to participate in our success through company shares.

We believe in equality and the power of intercultural, interdisciplinary teams. All qualified applicants will receive consideration for employment without regard to color, race, religion, gender, national origin, or disability.

We welcome unsolicited applications and are currently seeking additional personnel in the following teams.
