In this role, you will design and lead the implementation of industrial cybersecurity solutions for our clients, ensuring the protection and resilience of their Operational Technology (OT) and Industrial Control Systems (ICS/SCADA) environments. You will be responsible for defining the security strategy, framework, and architectures to mitigate risks, safeguard operational continuity, and secure critical infrastructure. Your work will involve designing secure OT architectures, ensuring solutions meet compliance standards (IEC 62443, NIST 800-82, ISO 27019, etc.), architecting network segmentation strategies (Purdue, Zero Trust), and providing expert oversight for incident response and security best practices.
Responsibilities
* Design and architect secure industrial environments (ICS/SCADA, DCS, PLCs, IIoT), defining controls to mitigate vulnerabilities
* Define and implement OT security architecture frameworks, ensuring solutions meet standards like IEC 62443, NIST 800-82, ISO 27019, NIS2, and sector-specific regulations.
* Design and govern IT/OT network segmentation strategies, applying principles like Zero Trust, industrial DMZs, and Purdue model segmentation.
* Architect the integration of OT security monitoring tools (e.g., Nozomi Networks, Claroty...) into the broader security ecosystem.
* Develop and maintain OT security roadmaps, reference architectures, and security patterns.
* Stay up to date with emerging OT threats and translate their impact into architectural design requirements.
Qualifications
* Degree in Telecommunications Engineering, Computer Science, Industrial Engineering, Electronics, Automation, or a related field.
* 5+ years of experience in OT cybersecurity, with proven experience in an architectural or design role.
* Proven experience designing secure OT solutions compliant with standards (IEC 62443, NIST 800-82).
* Experience architecting solutions with security tools for ICS environments (Nozomi, Claroty, Armis...).
* Ability to design resilient architectures to defend against cyber threats targeting critical infrastructure.
* Minimum B2 English level (projects may have an international scope).
Holding at least one of the following certifications is a plus:
* CISM, CISSP, GIAC (GRID, GICSP, GCIP), CompTIA Security+
