Full job description

Position Summary:

Design, implement, and maintain security controls across enterprise IT networks and Operational Technology (OT) environments (including manufacturing and plant floor systems). Ensure systems are secure, compliant, and resilient in a regulated pharmaceutical manufacturing setting.

Key Responsibilities:

Network Security (IT):
Design, implement, and manage security architecture across LAN/WAN, wireless, VPN, firewalls, and cloud connectivity (Azure/Entra ID environments).
Administer and optimize perimeter and internal segmentation controls (firewalls, NAC, DNS security/Cisco Umbrella, proxies).
Monitor network traffic for anomalies; collaborate with SOC/MDR partners (e.g., Arctic Wolf) to triage and respond to alerts.
Manage VPN, remote access, and secure site-to-site connectivity across manufacturing plants, distribution centers, and corporate offices.
Support identity and access controls for network infrastructure (802.1x, RADIUS, privileged access).
OT/ICS Security:
Assess and secure OT environments including SCADA, PLCs, DCS, HMIs, and manufacturing execution systems (MES).
Implement IT/OT segmentation (Purdue Model alignment), including DMZs between corporate IT and plant floor networks.
Conduct OT asset inventory, vulnerability assessments, and risk scoring specific to legacy and vendor-locked industrial systems.
Partner with Manufacturing, Engineering, and Automation teams to embed security requirements into OT change control, patch management, and vendor remote access.
Ensure OT security controls align with regulatory constraints (validated systems, GxP change control) without disrupting production uptime.
Cybersecurity Program Support:
Support NIST CSF 2.0-aligned governance activities, risk assessments, control gap remediation, and regulatory audits (FDA 21 CFR Part 11, GxP, SOC 2 Type II, DSCSA-related systems).
Support penetration testing and remediation cycles for network and OT-facing assets.
Participate in incident response for network/OT security events, including forensics and root-cause coordination with managed security partners.
Maintain network security documentation, diagrams, standard operating procedures, and technical policy artifacts.
Provide input into vendor risk assessments for network and OT equipment/software suppliers.

EDUCATION & QUALIFICATIONS

 Bachelor's degree in Computer Science, Information Security, Engineering, or related field (or equivalent practical experience).

 Preferred Certifications: CISSP, GICSP, CCNP Security, CCNA, ISA/IEC 62443 Cybersecurity Certificate, or equivalent.

REQUIRED SKILLS (explicitly call out must-have and nice-to-have skills expectations)

Note: Kindly enter any specific/relevant must have experience requirement against any of the below mentioned skills

Must-have Skills:

 10–12 years of progressive network security experience with demonstrable hands-on exposure to both IT and OT/ICS environments.

 Strong working knowledge of firewalls, network segmentation, VPN, NAC, IDS/IPS, and secure remote access architectures.

 Practical experience with OT/ICS security frameworks (IEC 62443, NIST SP 800-82) and Purdue Model segmentation.

 Familiarity with SCADA / PLC / DCS environments and operational constraints of legacy industrial systems.

 Experience with cloud network security in Azure / Entra ID or equivalent environments.

 Solid understanding of NIST CSF 2.0 and broader security governance frameworks.

 Experience with SIEM/MDR-based monitoring and incident response workflows.

Strong technical documentation skills (network diagrams, risk assessments, SOPs).

Nice-to-have Skills:

 Prior experience in pharmaceutical, life sciences, or other regulated manufacturing environments (GxP, validated systems, DSCSA/serialization awareness).

 Experience working alongside managed security service providers (MDR/SOC partners e.g., Arctic Wolf) and coordinating cross-functional incident response.

 Exposure to identity lifecycle and privileged access management (PAM) concepts as applied to network devices and OT assets.

IDEAL CANDIDATE PROFILE & PREFERENCES

 Proven ability to balance IT security rigor with OT operational realities (uptime, safety, validation constraints).

 Strong cross-functional collaboration skills (able to work seamlessly with Manufacturing, Automation/Engineering, Compliance, and Quality teams).

 Analytical and methodical approach to risk assessment and incident triage.

 Clear written and verbal communication for both technical and non-technical stakeholders.
