Job Technologies
Your role in the team
- Contribute to the development and continuous improvement of our QKD payload, from concept through flight qualification.
- Führen Sie technische Entscheidungen in Ihrem Bereich herbei und übernehmen Sie die Verantwortung für die Designentscheidungen von Subsystemen.
- Collaborate closely with electronics engineers (opto-electronics, digital/analog, FPGA interfaces) and thermo-mechanical engineers (thermal control, structural design).
- Plan and execute laboratory verification, characterization, and system-level testing of optical, electronic, and QKD-specific components.
- Prepare technical documentation, test reports, interface specifications, and customer deliverables.
- Support external environmental and space-qualification campaigns (vibration, TVAC, radiation, EMC).
- Contribute to continuous systematization and maintain clear requirements, interfaces, and architecture documentation.
- Work across several mission and technology projects simultaneously, contributing QKD expertise and hands-on engineering.
