Job Summary
In this role, you analyze QKD network architectures, perform technical trade-offs, and use modeling tools to derive system requirements for satellite-based, terrestrial, and hybrid QKD networks.
Your role in the team
- We are looking for a QKD System Architect to support studies and engineering activities for satellite-based, terrestrial, and hybrid QKD networks.
- In this role, you will assess QKD network architectures, perform technical trade-offs, use modelling and simulation tools, and derive system and interface requirements.
- You will act as the QKD expert in multidisciplinary teams and large consortia, connecting QKD theory, device implementation, network concepts, security considerations, and practical engineering constraints.
- You will prepare and present technical results, participate in project reviews, and engage with customers, partners, governmental agencies, and space agencies.
- Perform system and network studies for satellite-based, terrestrial, and hybrid QKD networks.
- Evaluate QKD architectures, protocols, trust models, implementation options, assumptions, limitations, and security implications through structured trade-offs.
- Use modelling and simulation tools to assess QKD performance, coverage, key availability, and operational constraints.
- Derive system, network, interface, and security-related requirements and contribute QKD expertise to system architectures and network integration concepts.
- Prepare technical documentation and present results in project, design, and review meetings.
- Work closely with multidisciplinary engineering teams and contribute to large international consortia.
- Engage with governmental agencies, space agencies, customers, and project partners on QKD-related topics.

Our expectations of you
Education
- University degree in physics, quantum technologies, electrical engineering, computer science, mathematics, or a related technical field.
Qualifications
- Sound understanding of QKD principles, protocols, network concepts, trust models, and practical limitations.
- Understanding of QKD devices, including their architecture, implementation principles, limitations, and security-relevant assumptions.
- Ability to bridge theoretical security concepts with practical engineering constraints.
- Strong communication skills and the ability to interact confidently with technical and non-technical stakeholders.
- High level of ownership, structured thinking, and reliability in security-critical environments.
- Willingness to attend on-site review meetings and undertake project-related travel.
- Knowledge of relevant QKD, cryptographic, or communication security standards, including ETSI, ITU-T, or Common Criteria.
Experience
- Experience with system studies, technical trade-offs, modelling or simulation, and requirements engineering.
- Experience with satellite-based QKD, space-based quantum communication, optical satellite links, or satellite mission studies.
- Experience working in large international consortia, space-agency projects, or formal technical reviews.
- Hands-on laboratory experience with QKD devices, optical systems, photonic components, or quantum communication test setups.
- Experience developing or operating validation equipment, testbenches, or laboratory procedures for QKD.
- Experience with certification, evaluation, or assurance processes for security-critical technologies.
- Experience with device characterization, side-channel analysis, implementation attacks, physical-layer security, or QKD security proofs.
