Betzdorf, Luxembourg

SES is recruiting a (Senior) Engineer, Quantum Communication who will support the preparation of technical proposals in response to international tenders and contribute to developing, implementing, and improving ground- and space-based services and systems.

Key activities include the technical aspects of Quantum Key Distribution Networks (QKDN), both terrestrial and space-based, following up on the procurement of terrestrial and satellite units and subsystems from definition to launch and operations, as well as being the prime point of contact for subcontractors and the SES team regarding the technical matters of different Quantum-related projects.

The (Senior) Engineer, Quantum Communication will be integrated into an international team of highly skilled engineers and gradually take on more responsibilities. Depending on the projects' nature and scope, he will either be in charge or supporting the below-listed responsibilities. One of the projects in which the (Senior) Engineer, Quantum Communication will work is EAGLE-1. SES is heading a consortium of industrial partners to create a quantum cryptographic communications system (EAGLE-1) under the agreement with ESA, enhancing Europe's leadership in quantum communications. It's a novel platform for distributed networks that provides a global service for next-generation encryption keys.

You will be responsible for (this is not an exhaustive list):

  • Deliver proposals, projects, and services to external and internal customers within the agreed budget, specification, and schedule, meaning:
