OTICS Network Security Architect

The client operates industrial/environmental facilities with both traditional IT and OT/industrial environments. As part of the acquisition/integration, the Security team needs support analyzing OT site scan/discovery data and translating it into network/security architecture diagrams covering devices, zones, segmentation and data flows. For profile screening, we can primarily look for OT/ICS Network Security experience, particularly industrial network architecture, Purdue/ISA-95, OT segmentation, SCADA/industrial environments, IEC 62443/NIST 800-82, and network diagramming/documentation. Key Responsibilities Turn raw OT site scan data (asset inventories, traffic captures, device metadata) into detailed, client-ready network diagrams, devices, zones, segmentation, and data flows, structured against a recognized OT reference model such as Purdue/ISA-95. Maintain a consistent diagramming standard across sites, flag data gaps or anomalies for follow-up, and iterate based on feedback from the engagement lead and client. Required Qualifications Demonstrated experience with OT/ICS or industrial control system network environments, and solid grounding in how they differ from standard IT networks. Ability to read scan/discovery data and translate it accurately into polished, presentation-ready diagrams, with strong supporting documentation for both technical and executive audiences. Nice to Have Prior experience producing OT network diagrams as a deliverable on a security assessment or M&A/integration engagement, familiarity with common industrial protocols and OT frameworks (e.g., IEC 62443, NIST SP 800-82). This is a remote position. CLOUDSCOUTS SOFTWARE SOLUTIONS LLC
