Job Description
As part of the team you will have the following responsibilities:
- Define end‑to‑end quantum communication system architectures (e.g., QKD links, quantum repeater concepts, space‑to‑ground links).
- Translate mission, security, and performance requirements (SKR, QBER, link budget) into subsystem specifications.
- Support/lead design of quantum optical hardware (sources, detectors, time-tagging, synchronization, stabilization).
- Oversee breadboarding, prototyping, and design-for-test/assembly (DFT/DFA).
- Plan and execute integration, verification, and validation (IV&V) activities for lab, field, and over‑the‑air trials (terrestrial fiber/free-space and space segments).
- Develop test plans, procedures, and automated test scripts; analyze results and generate test reports.
- Perform optical link budgets, channel modeling (attenuation, turbulence, background noise), alignment and pointing, timing/synchronization.
- Interface with classical communication layers (key management, control plane) and security infrastructure.
- Ensure compliance with safety, EMC, environmental, and, where applicable, space qualification standards (e.g., vibration, thermal vacuum, radiation).
- Contribute to FMEAs, fault trees, design reviews, and configuration management.
- Advise internal teams and customers on technology trade‑offs, roadmaps, and risks.
- Prepare design documents, ICDs, test reports, and operations manuals; present findings to technical and non‑technical stakeholders.
Qualifications
You will have the following qualifications and relevant experience:
- Master’s or PhD in Physics, Electrical/Photonics Engineering, Aerospace, or related field.
- 8+ years in quantum communications/QKD, photonics, or optical comms.
- Experience with space segment design, AIT/AIV, and environmental qualification.
- Proficiency with link budgets and channel models for fiber and/or free‑space; familiarity with turbulence and background models.
- Strong technical writing and stakeholder communication; able to produce clear documentation.
- Fluency in English is mandatory; knowledge of another European language is an advantage.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
The quantum communication engineer function is critical for translating theoretical quantum key distribution (QKD) protocols into deployed, secure networking infrastructure. This role exists at the nexus of telecommunications, photonics, and aerospace systems, structurally necessary to validate and harden quantum-enabled cryptography for sensitive use cases in space and terrestrial environments. The work mitigates the systemic risk posed by post-quantum adversaries by establishing verified, resilient quantum-safe links. Its value-chain impact lies in de-risking high-Technology Readiness Level (TRL) photonics hardware and establishing the operational readiness standards required for long-distance quantum link establishment and maintenance, directly supporting sovereign security and digital resilience initiatives.
The adoption curve for quantum communication technology is defined by the technical challenge of integrating highly sensitive quantum optical components into robust, large-scale networks, particularly within the harsh constraints of space environments. This role positions itself within the quantum enablement segment, bridging foundational physics research and practical deployment readiness for the defense and space sectors. Current industry focus lies on bridging classical and quantum capabilities at scale, recognizing that the long-term strategic advantage of quantum communication—absolute security—is dependent on the reliability and scalability of the physical layer. The ecosystem faces constraints related to the maturation of critical quantum components, such as single-photon sources and detectors, which require rigorous space qualification procedures to transition from laboratory prototypes to flight-ready assets.
Link budget optimization and atmospheric channel modeling remain key barriers for free-space quantum communications, demanding specialized engineering expertise to ensure effective photon transfer across variable distances and through atmospheric turbulence. Furthermore, the global workforce lacks a sufficient pipeline of engineers skilled in both quantum optics and established space-system engineering practices, leading to project timeline extensions and increased integration complexity. The combination of high precision quantum hardware design and stringent environmental validation standards, often governed by multi-national public funding cycles, necessitates engineers who can manage both research translation pathways and the rigorous quality assurance processes expected in aerospace applications.
The functional architecture for this engineering role revolves around complex electro-optical systems development and validation. Core capability domains include systems integration, focusing on the interface between cryogenic or stabilized quantum sources/detectors and classical control, timing, and synchronization electronics. The utilization of optical link budget simulations and atmospheric modeling tools is essential for predicting channel performance in terrestrial fiber and free-space environments. This proficiency ensures that hardware designs meet mission-critical performance requirements, particularly Key Rate (SKR) and Quantum Bit Error Rate (QBER) targets, which directly translate to cryptographic security robustness. Expertise in Design for Test/Assembly (DFT/DFA) and Integration, Verification, and Validation (IV&V) protocols is leveraged to industrialize prototypes, ensuring components adhere to rigorous standards like EMC and thermal vacuum certification necessary for space qualification. This comprehensive technical skill architecture is necessary to successfully transition fragile quantum laboratory setups into operationally reliable communication systems.
