Employment: Full-time · Industry / R&D Interface

About AQLS
AQLS develops next-generation photon-pair sources, quantum memories, and
integrated photonic subsystems to enable quantum applications. Our mission is to
bring lab-grade quantum light technologies to industry-grade, deployable products.
To strengthen our team, we are recruiting a Quantum Networking Systems Engineer
at the intersection of optics, quantum communication, and systems engineering.

Your Role
As Quantum Networking Systems Engineer, you will design, implement, and validate
quantum networking architectures based on AQLS’ hardware platforms (PPS-DG
photon-pair sources, quantum memories, etc.).
You bridge experimental quantum optics, telecommunications, and network-level
engineering. Your work enables us to deploy quantum communication infrastructure,
operate quantum networking testbeds, and quantum repeater demonstrators.

Key Responsibilities
Quantum System Architecture
• Design system architectures combining entangled photon sources, quantum
memories, detectors, optical switches, and classical sync/control.
• Develop interface and protocol specifications for quantum networking modules
(e.g., entanglement swapping, quantum state synchronization, heralding logic).
Experimental & Networking System Integration
• Integrate AQLS hardware into network environments.
• Perform end-to-end network-level performance characterization.
• Develop control logic and orchestration software for quantum nodes (Python).

Your Profile
Required
• MSc or PhD in Physics, Photonics, Electrical / Quantum Engineering.
• Hands-on experience in quantum optics with single photons.
• Experience with timing electronics (TDCs, FPGAs, synchronization).
• Proficiency in Python for experimental control.
• Strong system-engineering mindset (requirements, testing, debugging).
Nice to Have
• Experience with entanglement-based quantum communication.
• Exposure to relevant telecom network standards.
• Experience working in industry-academia collaborations.
• Excellent communication skills in English.

What We Offer
• Work at the forefront of real-world quantum networking and help shape
Europe’s quantum infrastructure.
• A international, interdisciplinary environment: photonics, quantum physics,
system engineering.
• Flat hierarchies, fast decision cycles, and direct impact on product
development.
• Opportunities to publish, file patents, and close collaborate with leading
European research partners.
• Long-term career development in our growing team.
