Optical Engineer

Celare Quantum Communications is a Danish high-tech quantum technology company with a mission to radically improve cybersecurity and enable trusted global data sharing.

Our core product is a unique, cutting-edge technology born from years of university research called Continuous-Variable Quantum Key Distribution (CV-QKD). This technology enables post-quantum secure key exchange for protecting sensitive data across critical infrastructure.

Celare partners with local and international governments, telecom operators, data centers, banks, defense ministries, and leading academic institutions. Over the past year our team has successfully launched commercial pilot deployments of our technology.

The Celare Team

We are a highly specialized and ambitious team of quantum engineers, serial entrepreneurs, laser, RF and electronics specialists, mathematicians, software engineers, and IC and FPGA designers.

Based in Copenhagen, we combine deep academic expertise with hands-on experience in launching complex, high-impact technology products.

The Role

In this role you will get a unique opportunity to work at the cutting edge of quantum technology development.
