This role demands a deep technical expert with proven experience in securing critical infrastructure and industrial systems, who can also provide strategic leadership and foster a culture of security awareness in a highly sensitive operational context. The SM will safeguard the availability, integrity, and confidentiality of our plant control systems, ensuring business continuity and compliance with sector-specific regulations.

Key Responsibilities:

• Strategic Leadership & Program Development:

• Design and implement the OT/ICS cybersecurity strategy and roadmap, ensuring alignment with enterprise-wide security objectives, industry standards (such as ISA/IEC 62443 and NIST CSF for ICS), and broader business goals.

• Build and continuously enhance the OT/ICS security program by developing tailored policies, standards, procedures, and architectural frameworks suited to industrial environments.
• Partner closely with plant operations, engineering, and IT teams to embed security into OT/ICS initiatives and day-to-day operational workflows.

• Monitor the evolving landscape of OT/ICS threats, vulnerabilities, and emerging technologies to proactively strengthen and refine the organization's cybersecurity posture.

• OT/ICS Security Operations & Management:

• Direct the daily security operations across all OT/ICS environments at plant sites, including continuous monitoring, threat detection, and incident response.

• Supervise the deployment and ongoing management of OT/ICS-specific security controls, including:

• • Network segmentation aligned with the Purdue Model and Zero Trust principles for OT
• Vulnerability assessment and patch management for industrial components (PLCs, DCS, SCADA, HMIs)
• Implementation of industrial firewalls, intrusion detection systems (IDS), and anomaly detection tools
• Secure remote access solutions for both internal users and third-party vendors
• Endpoint protection for industrial servers and workstations
• Deployment of data diodes and enforcement of secure data flows

• OT/ICS-focused backup strategies and disaster recovery planning.

• Lead and coordinate incident response efforts for OT/ICS systems, ensuring effective containment, remediation, recovery, and post-incident review.

• Enforce secure configuration practices and ensure compliance with baseline standards across all OT/ICS assets.

• Risk Management & Compliance:

• Perform in-depth risk assessments of OT/ICS environments to identify critical assets, potential threats, and existing vulnerabilities.

• Establish and maintain an OT/ICS risk register, documenting identified risks, mitigation strategies, and tracking residual risk levels over time.
• Ensure adherence to applicable national and international regulations and cybersecurity standards for critical infrastructure, such as NCIIPC guidelines (India) and sector-specific directives from regulatory bodies like CERC and PNGRB, where relevant.

• Lead and support both internal and external audits of OT/ICS cybersecurity, including regulatory inspections, and oversee the timely resolution of any identified issues or compliance gaps.

• Architecture & Engineering:

• Offer expert advisory on secure architecture for both new and existing OT/ICS deployments, ensuring cybersecurity is embedded from the initial design stage.

• Work closely with engineering teams to design and configure secure systems, including effective network segmentation within plant control networks.

• Assess, recommend, and lead the implementation of advanced OT/ICS security technologies and solutions to strengthen the overall security posture.

• Team Leadership & Development:

• Build and lead a high-performing team of OT/ICS cybersecurity specialists, providing mentorship and technical guidance.

• Cultivate a team culture focused on deep expertise, continuous learning, and proactive security practices.
• Oversee resource planning, performance management, and professional growth for team members.

• Drive the recruitment and onboarding of talent with specialized skills in OT/ICS security to strengthen team capabilities.

• Stakeholder Engagement & Awareness:

• Act as a liaison between IT security and plant operations/engineering teams, promoting effective collaboration and mutual understanding.

• Design and deliver targeted OT/ICS cybersecurity awareness and training programs tailored for plant staff, operators, and engineering personnel.
• Clearly articulate complex OT/ICS security risks and concepts to diverse audiences, including both technical teams and senior leadership.
• Oversee and maintain productive relationships with external OT/ICS security vendors and service partners.
