QKD System Architect - Satellite Network Studies (all genders)

The Role

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 …
