• Design secure cloud and hybrid environments that support interoperability between on-premise ICS/SCADA systems and cloud-based analytics or IoT platforms.
• Develop and enforce cloud security standards, reference architectures, and design patterns across Azure, AWS, GCP, and private cloud environments.
• Establish security baselines and guardrails for infrastructure-as-code, network design, IAM, encryption, and data protection.
• Collaborate with Cloud Engineering and DevOps teams to embed secure-by-design principles into CI/CD pipelines and deployment processes.
• Conduct architecture reviews, threat modeling, and risk assessments for digital manufacturing and enterprise initiatives.
• Lead cloud security assessments and manage remediation efforts stemming from penetration tests, audits, and compliance reviews.
• Evaluate and select cloud security technologies (CSPM, CWPP, CASB, SIEM, DLP, Zero Trust frameworks).
• Drive the adoption of Zero Trust principles across hybrid and OT-connected environments.
• Provide expert guidance on secure network segmentation between IT and OT systems.
