Cybersecurity Architect, Cryptography Projects

Location: Tubize #ON-SITE

The Cybersecurity Engineer for Cryptography Projects needs to be a technical passionate. Based on their existing background in IT, telecommunication systems and/or cybersecurity, they will be eager to discover new technologies to continuously expand and reinforce their expertise in these fields. They will put their expertise at the service of both the security-centric projects of the Security discipline and the secure-by-design aspects of the projects lead by the other disciplines.

Your Mission:

• Design customer-centric cryptographic architectures by analyzing security needs, defining optimal solutions, and serving as the primary technical interface for stakeholders.
• Lead system specification, design, and Make/Team/Buy decisions, collaborating with hardware, software, security, and QA teams to deliver compliant, high-assurance cryptographic solutions.
• Act as the technical authority on cryptography, driving innovation, risk assessments, and best practices to counter evolving threats (e.g., post-quantum algorithms) and meet regulatory standards (e.g., FIPS, Common Criteria).
• Own technical documentation (HLD/LLD, test plans, user manuals) with end-to-end traceability—from requirements to implementation, validation, and deployment—ensuring audit readiness.
• Support sales/marketing teams in technical pre-sales activities (RFIs/RFPs, demos, PoCs) by translating complex cryptographic concepts into customer-facing solutions.
• Guide development and testing teams to ensure on-time delivery, security compliance, and performance optimization of cryptographic implementations.
• Assess and mitigate cryptographic risks (e.g., side-channel attacks, key management vulnerabilities) while aligning solutions with global security standards and customer-specific requirements.

What We Are Looking For

• Engineering degree in Telecommunications, Cybersecurity, or related STEM field with 5+ years designing embedded security systems (requirements, architecture, testing).
• 3+ years of experience in at least 3 of the following: model-based system engineering, Common Criteria certification, cybersecurity solution deployment (firewalls, anti-DDoS, risk management), IP/IPv6 networking, or embedded Linux.
• Hands-on expertise in cryptography-centric design, including classified information handling, crypto governance, EBIOS risk assessments, or translating business needs into technical security solutions.
• Proven experience with security certification frameworks (e.g., Common Criteria) and adherence to technical/governance constraints in high-assurance environments (classified or regulated sectors).
• Familiarity with tools like Capella, DOORS, Polarion, Jira, or LaTeX is a strong differentiator.
• Passionate about diverse tech integrations, continuous learning, and problem-solving with strong communication skills,
• Customer-focused mindset with a track record of pragmatic delivery, cross-functional collaboration, and bridging technical, business, and operational gaps—experience in knowledge sharing (seminars, webinars, whitepapers) is a plus.
