About the role

Systems Engineer developing Optical Ground Stations for space-based Quantum Key Distribution at Quantum Technology Laboratories. Collaborating on advanced technologies in optical and quantum communication fields.

Responsibilities

Contribute to the design, development, and manufacture of Optical Ground Stations (OGS) for satellite-to-ground Quantum Key Distribution (QKD) links
Take ownership of subsystem design decisions, including the optical front end, tracking systems, turbulence mitigation, time-bin/phase and polarization analysis modules, and single-photon detection modules
Collaborate 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 multiple mission and technology projects simultaneously, ensuring consistent architectural and performance standards

Degree in optical engineering, physics, electrical engineering, photonics, aerospace engineering, or a related field
Strong understanding of free-space optical communication, telescope systems, optics, and tracking/control concepts
Familiarity with quantum receivers, including single-photon detectors, low-noise readout electronics, polarization optics, and active stabilization methods
Hands-on experience with optical laboratory setups, measurement equipment, and system integration
Ability to work independently, make informed technical decisions, and drive iterative design improvements
Strong analytical skills and attention to detail, particularly in documentation, testing, and interface-driven development
Experience in any of the following is a strong plus: satellite-to-ground optical communication or QKD; control systems for tracking, pointing, and synchronization; adaptive optics for turbulence mitigation; field deployment of optical systems; environmental testing or hardware verification

Flexible work arrangements with a hybrid model combining remote and on-site collaboration
Attractive workplace with excellent infrastructure at Wienerberg
Balanced work–life integration
Friendly and humorous working atmosphere
Great Italian espresso
