Applied Cryptography Engineer

Are you looking for a new opportunity to join meaningful projects? To take part in activities that could contribute to security and safety in state-of-the-art technologies and fields of application? To join an international group with a successful track record in delivering Top-Tier Engineering services in Space, Defence and Cybersecurity sectors?

We are currently looking for an Applied Cryptography Engineer to join our specialised team on well-known INT-UQKD project and work from our beautiful premises in Libin, Belgium.

You will be responsible for the entire end-to-end cryptographic integrity of the system, from the physical (quantum) layer to the abstract (MPC) and application (PQC) layers. You will act as the key person that guarantees the security of the entire key generation and delivery chain.

Tasks and activities

The scope of work will include:

• Leading the security design of INT-UQKD protocol(s), covering the full stack: physical QKD key generation, resilient secret sharing, and the multiparty key delivery application across distributed communication.
• Developing the security models for the cryptographic primitives underpinning the protocol(s), ensuring that their implementation is formally robust against attacks, delivering a key delivery service that aligns with INT-UQKD security and operational requirements.
• Collaborating with the system architect to convert the system architecture into clear, technical requirements that enable the development team to implement the protocols securely and reliably.

Skills and experience

The following skills and experience are mandatory:

• University Degree (Master’s or PhD) in a relevant field (Mathematic, specialisation in Cryptography, Information, IT or Cyber-security, Quantum Physics, etc.).
• A proven experience in applied cryptography with deep theoretical and practical knowledge of the prevalent cryptographic schemes (QKD, Post- Quantum Cryptography (PQC), Multi-Party Computation (MPC), Threshold schemes (e.g. Shamir’s Secret Sharing).
• Concrete ability to design, analyse, and establish formal security proof of complex multi- layered cryptographic protocols against a range of adversities (computational, quantum, insider, etc.).
• System engineering experience with the ability to prepare documents following security requirements.
• Desire to work both independently and as part of a team, in an international, multicultural environment.
• Solution orientated mindset, with customer focused communication skills.
• Fluent in English, both written and spoken.
• Eligible for a EU personal Security clearance.

The following skills would be highly desirable.

• Experience with Model Based System Engineering (MBSE)
• Experience with operation and / or security assessment of quantum-safe

• Experience in project execution following international standards, such as space (ECSS, CCDS, IDSIS), military (MIL-STD, NATO) or regulatory (ETSI, ITU, 3GPP) standards.
• Experience in creating cybersecurity test plans, performing critical (including space-related) system cybersecurity testing, and analysing test results.
• Familiar monitoring protocols and OS tools, such as SNMP or Syslog.
• Familiar with secure software development life cycle (SDLC) principles and practices.
• Knowledgeable with automated software deployment, scaling, and management of containerized applications (Kubernetes)

Why should you apply?

• You will have the opportunity to work within leading space organisations across Europe.
• We encourage everyone to think outside the box and to push the boundaries of traditional knowledge. This role is an opportunity to join a forward-thinking company and allows for a deeper understanding of the industry.
