  • Job Summary

    In this role, you will design and optimize optical ground stations for satellite communication, working on components such as telescopes, detectors, and tracking systems.

    Your role in the team

    • Contribute to the design, development, and manufacturing of our Optical Ground Stations for satellite-to-ground QKD links.
    • Übernehmen Sie die Verantwortung für die Designentscheidungen der Subsysteme, einschließlich optisches Frontend, Tracking-Systeme, Turbulenzminderungssystem, Time-Bin/Phasen- und Polarisationsanalyse-Modul sowie Single-Photon-Detektionsmodule.
    • Work closely with experts in optics, electronics, control systems, and quantum communications to deliver robust, high-performance OGS solutions.
    • Integrate and optimize components such as telescopes, tracking cameras, beacon lasers, quantum receivers, polarization optics, and timing/synchronization modules.
    • Plan and execute laboratory verification, field testing, and link characterization campaigns for OGS prototypes and deployed systems.
    • Contribute to and maintain system requirements, optical budgets, interface definitions, and architecture documentation.
    • Perform system-level modeling and analysis of link performance (attenuation, turbulence, pointing/tracking error budgets, synchronization).
    • Support on-site installation, maintenance, and troubleshooting of OGS systems at customer locations or demonstration sites.
    • Prepare technical documentation, test reports, interface specifications, and customer deliverables.
    • Collaborate across several mission and technology projects simultaneously, ensuring consistent architectural and performance standards.
