System Engineer - Optical Ground Station for Space-Based QKD (all genders)

We are expanding our team and are looking for a motivated systems engineer to drive the development of our next-generation Optical Ground Stations (OGS) for space-based Quantum Key Distribution (QKD). In this role, you will work at the interface of free-space optics, precise tracking of satellites (LEO, GEO), quantum detection systems, and system-level engineering.

Our ground stations integrate high-performance optical subsystems, telescopes, fine-tracking sensors, adaptive optics system, beacon lasers and our state-of-the-art Quantum Receiver, designed for ultra-low-noise single-photon detection, active polarization compensation, and high-rate key generation. If you are excited about building real-world infrastructure for long-distance quantum communication, this role is for you.

• 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.


• Experience with optical laboratory setups, measurement equipment, and hands-on system integration.


• Ability to work autonomously, make informed technical decisions, and drive design iterations.


• Solid analytical skills and attention to detail, especially 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 turbulance mitigation
  
  
  • Field deployment of optical systems
  
  
  • Environmental testing or hardware verification
  
  
  
  


• Excellent communication skills and motivation to work in interdisciplinary engineering teams.
