Job Summary
In this role, you will develop secure architectures for integrating QKD devices into communication networks, conduct security risk assessments, and support certification activities.
Your role in the team
- At Quantum Technology Laboratories GmbH (qtlabs), we are developing next-generation quantum communication technologies for space and terrestrial applications. Our work combines quantum optics, cryptography, and advanced engineering to create practical systems for secure communication in the quantum era.
- Based in Vienna, our team brings together experts in quantum key distribution (QKD), optical communication, system engineering, and security-critical technologies. We are now looking for an Expert for secure implementation of QKD Systems to strengthen our expertise in the secure implementation, validation, and certification readiness of QKD devices and networks.
- The Role
- We are looking for an Expert for secure implementation of QKD Systems to strengthen the security engineering, system engineering, and certification readiness of our next-generation quantum communication systems.
- In this role, you will develop architectures for integrating QKD devices into larger communication networks and infrastructures. You will contribute to security risk assessments, identify threats and countermeasures at device level, and derive requirements for the secure implementation of QKD devices and QKD networks.
- Working closely with Security Architects, Security Proof Experts, system engineers, hardware and software teams, you will help align security concepts, implementation assumptions, and practical system designs. Your work will bridge security engineering and system engineering and contribute to the development of secure, validated, and certifiable QKD devices.
- You will also support certification activities, contribute to validation strategies, assist in the development of validation equipment and test benches, and engage with stakeholders such as governmental agencies, space agencies, evaluation laboratories, partners, and customers.
- Key Responsibilities
- Develop secure architectures for integrating QKD devices into terrestrial, space-based, and hybrid communication networks.
- Contribute to security risk assessments for QKD devices, QKD networks, and their operational environments.
- Identify and evaluate threats, countermeasures, and security requirements at the level of QKD devices, interfaces, network integration, and operational procedures.
- Translate security concepts, assumptions, and implementation requirements into concrete system engineering inputs.
- Work closely with Security Architects, Security Proof Experts, and engineering teams to align security proofs, implementation assumptions, system design, and secure implementation.
- Lead or assist certification-related activities, including evidence preparation, technical documentation, and coordination with evaluation laboratories.
- Assist in the development of validation equipment, testbenches, test procedures, and validation strategies for QKD devices.
- Review and contribute to system designs, device architectures, interface specifications, and implementation choices from a security perspective.
- Engage with governmental agencies, space agencies, customers, partners, and certification bodies on security-related topics.
