OT Security Architecture & Governance

• Develop, implement, and enforce OT security policies, procedures, reference architectures, and technical standards aligned with the organizations security framework and applicable requirements, including relevant CEA cybersecurity requirements, NCIIPC advisories where applicable, and ISA/IEC 62443 practices.
• Design and implement risk-based OT network architectures using zones, conduits, security boundaries, industrial demilitarised zones, controlled data flows, and resilient communications. Ensure designs address distributed sites, central and local SCADA, plant controllers, substations, remote operations, legacy equipment, latency, OEM dependencies, and loss-of-communications scenarios.
• Lead OT security governance, define minimum baseline security standards, manage approved deviations, and track compliance across wind, solar, hydro, and associated grid-connected assets.

• Lead the design, deployment, testing, commissioning, and validation of OT security controls, including network segmentation, industrial firewalls, secure remote access, privileged access, endpoint controls appropriate for OT, asset visibility, security monitoring, logging, backup protection, and resilient recovery arrangements.
• Work closely with OEMs, EPC partners, engineering teams, and O&M teams to define security requirements and validate their implementation during design reviews, procurement, factory acceptance testing, site acceptance testing, commissioning, and operational handover.
• Establish and monitor secure configuration baselines for OT assets; manage hardening, approved deviations, firmware and software versions, unsupported or end-of-life components, vulnerability remediation, compensating controls, and risk-based maintenance throughout the asset lifecycle.

• Implement and operate OT security monitoring that provides asset visibility, identifies anomalous communications and malicious activity, generates actionable alerts, and integrates appropriately with enterprise security operations without introducing unacceptable risk to plant performance or availability.
• Lead the coordinated response to OT cybersecurity incidents, prioritising personnel safety, plant stability, evidence preservation, regulatory obligations, controlled containment, and restoration of operations, Coordinate with site operations, engineering, IT, OEMs, legal, communications, and leadership through defined escalation and crisis-management procedures.

• Responsible for periodic OT audit and risk assessments, VA/PT, and compliance assessments aligned with CEA, RLDC/NLDC, SECI requirements.

• Work closely with IT, cybersecurity, network, and infrastructure teams to ensure secure IT–OT interfaces.
• Support cross-functional OT security initiatives

• Conduct OT security training for site engineers, OEM partners, and contractors per internal policy requirements.
• Develop documentation including system architecture diagrams, SOPs, incident playbooks, and audit compliance evidence.

Experience : 12 to 17 Years
