[Remote] OT Security Analyst

Note: The job is a remote job and is open to candidates in USA. Graham Packaging is a sustainable packaging manufacturing company. The OT Security Analyst is responsible for securing industrial control systems and manufacturing environments through OT security monitoring, threat detection, incident response, vulnerability management, and implementation of cybersecurity controls. The role bridges IT and OT domains, collaborates with plant and engineering teams, and requires travel to manufacturing facilities.

Responsibilities

• Monitor industrial networks, control systems (SCADA, PLCs), and plant environments for cyber threats and anomalies. Investigate alerts generated by tools such as Dragos and CrowdStrike, and coordinate incident response actions including containment and recovery with plant operations teams
• Identify threats targeting industrial control systems by analyzing OT network traffic, device behavior, and threat intelligence. Perform root cause analysis of incidents impacting manufacturing environments
• Assess vulnerabilities across OT assets including PLCs, HMIs, and embedded systems. Partner with engineering and plant teams to prioritize remediation activities that minimize production risk
• Support the design, implementation, and maintenance of secure architectures for PLCs, DCS, and embedded systems. Ensure adherence to segmentation, least privilege access, and secure communication protocols within plant environments
• Deploy, maintain, and optimize OT and endpoint security platforms including Dragos, CrowdStrike, and Linux-based monitoring tools. Tune detection rules and alerts to reduce false positives and improve threat visibility
• Assist in implementing network segmentation strategies between IT and OT environments. Validate firewall rules, remote access controls, and secure vendor connectivity into plant networks
• Work closely with plant managers, controls engineers, and IT teams to integrate cybersecurity controls into manufacturing processes without impacting uptime or throughput
• Ensure OT security practices align with frameworks such as NIST Cybersecurity Framework (CSF), ISA/IEC 62443, and internal company cybersecurity policies. Support audits and risk assessments specific to manufacturing operations
• Stay current on emerging OT threats and vulnerabilities. Contribute to improving the organization’s overall OT security posture through new controls, tools, and best practices
• Remote-based role with expected travel: North America manufacturing sites: primary travel (approximately 25–40%); International travel (Europe & South America): occasional, project-based

Skills

• 3–7 years of experience in cybersecurity, with direct experience in OT/ICS environments within manufacturing required
• Proven experience implementing cybersecurity controls in industrial or production environments
• Strong understanding of OT networks, industrial protocols (Modbus, OPC, Ethernet/IP), and control systems architecture
• Hands-on experience with:
• PLCs and embedded systems
• Dragos or similar OT security platforms
• CrowdStrike or equivalent endpoint detection tools
• Linux environments and scripting
• Familiarity with network segmentation, firewalls, and remote access in OT environments
• Understanding of IT/OT convergence risks and mitigation strategies
• Strong analytical and troubleshooting skills in complex operational environments
• Ability to communicate effectively with both technical teams and plant operations personnel
• Ability to balance security requirements with operational uptime and safety priorities
• Hands-on experience supporting plant operations or working with controls/automation teams is strongly preferred
• Bachelor's degree in Cybersecurity, Information Technology, Engineering, or related field preferred (or equivalent experience)
• GICSP (Global Industrial Cyber Security Professional)
• CISSP, CISM, or equivalent
• Vendor-specific certifications (CrowdStrike, Dragos) a plus
• This is a remote position with travel required to manufacturing facilities primarily in North America, with occasional travel to Europe and South America
• North America manufacturing sites: primary travel (approximately 25–40%)
• International travel (Europe & South America): occasional, project-based
