Applied Materials•Santa Clara, CA

19d

About The Position

Security Architecture & Design Develop secure architectures for OT systems, including ICS, SCADA, PLCs, and HMIs. Conduct design and architecture reviews to ensure compliance with security standards (e.g., ISA/IEC 62443, NIST 800-82). Implement network segmentation, secure remote access, and least-privilege models across IT/OT boundaries. Drive architectural reviews and influence security strategy across the enterprise Perform risk assessments and vulnerability analysis for OT environments. Ensure compliance with regulatory frameworks (e.g., RMF, ISO 27001). Develop proactive remediation strategies aligned with industry frameworks and operational priorities. Evaluate emerging technologies and tools to strengthen OT/IoT security posture. Work closely with facilities and lab manufacturing teams to integrate security into operational workflows. Provide guidance and training to lab, manufacturing team personnel on OT security best practices Deep expertise in OT/IoT security architecture and vulnerability management. 7-10 years in OT/ICS cybersecurity with proven experience designing secure industrial environments. Strong knowledge of ICS protocols (Modbus, OPC, Ethernet/IP) and industrial control systems. Familiarity with ISA/IEC 62443, Purdue Model, NIST CSF, ISO 27001. Hands-on experience with Armis, Dragos, Claroty, or similar platforms. Experience in highly regulated environments (energy, manufacturing, pharma). Knowledge of threat modeling and penetration testing for OT systems. Familiarity with emerging technologies like IoT in industrial environments. Semiconductor or advanced manufacturing experience. Knowledge of SEMI standards (E187/E188/E191). Certifications: GICSP, CISSP, or equivalent. Strong communication skills for cross-functional collaboration. Ability to translate technical security concepts for non-technical stakeholders.
