Quantum Key Distribution Payload Engineer at Quantum Technology Laboratories developing QKD payloads for space applications and collaborating with interdisciplinary teams in Vienna.
Responsibilities
Contribute to the development and continuous improvement of our QKD payload, from concept through flight qualification.
Drive technical decisions within your domain and take ownership of subsystem design choices.
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).
Requirements
Degree in physics, electrical engineering, photonics, aerospace engineering, or a related field; background in Quantum Key Distribution (QKD) or quantum optics strongly preferred.
Solid understanding of QKD protocols, photon sources and detectors, optical components, timing/synchronization, and system architectures.
Experience with laboratory work (optical setups, measurement equipment, data acquisition).
Ability to work autonomously, make informed technical decisions, and drive design iterations.
Strong analytical mindset with attention to detail and disciplined documentation practices.
Experience in space systems, environmental testing, or hardware verification is a plus but not required.
Benefits
Flexible work arrangements with a hybrid model combining remote and on-site collaboration
