OT / ICS Architecture Lead (ID: 3475)

As an OT / ICs Architecture Lead, you will:

• Design high-level and low-level OT architecture diagrams covering ICs, SCADA, DCS, PLC/RTU, and plant automation environments.
• Lead OT system modernization initiatives, including migration from legacy and insecure industrial protocols to secure alternatives.
• Drive IT–OT convergence architecture, covering identity management, asset visibility, patch management, and secure remote access.
• Provide architectural guidance to OT engineering, operations, and cybersecurity teams.
• Define and enforce standards for OT system configuration, hardening, patching, asset inventory, and backup/restore processes.
• Ensure regulatory and industry compliance across OT environments (ISO 27001, NERC CIP, Pharma GxP, Oil & Gas standards).
• Maintain and govern OT architecture documentation and repositories across plants and industrial sites.

What You Bring to the Table:

• 10+ years of hands‑on experience in OT, ICs, or industrial automation architecture.
• Strong experience working with ICs/OT technologies including PLCs, SCADA, DCS, HMI, and Historian systems.
• Deep understanding of industrial communication protocols such as Modbus, OPC UA/DA, DNP3, PROFINET, and EtherNet/IP.
• Proven experience in designing and securing OT environments in large-scale industrial or critical infrastructure settings.
• Solid knowledge of IT‑OT integration challenges, risks, and architectural patterns.
• Practical exposure to regulatory and compliance‑driven environments.
• Strong documentation skills for architecture standards, reference models, and operating procedures.

You Should Possess the Ability to:

• Translate complex industrial operations into secure, scalable OT architectures.
• Evaluate OT environments for risk, visibility gaps, and legacy security weaknesses.
• Lead protocol modernization efforts while minimizing operational disruption.
• Align OT architecture with cybersecurity frameworks, especially ISA/IEC 62443.
• Collaborate effectively with engineering, operations, and security stakeholders.
• Enforce architectural governance across multiple plants or industrial sites.
• Balance availability, safety, and security requirements in mission‑critical OT systems.

What We Bring to the Table:

• Opportunities to work on complex, large‑scale OT and industrial transformation programs.
• Exposure to mission‑critical environments where architecture decisions directly impact safety and operations.
• A role with architectural ownership and decision‑making authority.
• Engagement with modern OT security and IT‑OT convergence initiatives.
