This is an onsite position at the DuPont Spruance site. Candidates must live within a daily commutable distance to the site or be willing to relocate to the area at their own expense to be considered for this role.

What You’ll Do

Network Design & Administration

• Design, implement, and manage secure, resilient PCN architectures that support reliable site operations.

• Administer switches, VLANs, and domain controllers with a focus on uptime, performance, and scalability.

• Own firewall configuration, rules, and approvals to strengthen secure connectivity across the environment.

• Support key technology migrations, including Honeywell-related work, through pre-migration audits, switch reconfiguration, and VLAN changes.

Cybersecurity Implementation

• Shape and enforce cybersecurity practices designed for industrial control and manufacturing environments.

• Deploy and manage firewalls, IDS/IPS, antivirus, and endpoint protection solutions to reduce operational risk.

• Implement port locking and access controls that prevent unauthorized devices from connecting to the PCN.

• Represent the site in global cyber forums, including the Global Cyber Champions network and Honeywell Cyber Customer Advisory Board.

Monitoring & Incident Response

• Continuously monitor network traffic and system performance using tools such as Dell OpenManage, ActiveXperts, and LogicMonitor.

• Detect, analyze, and respond to anomalies, threats, or breaches.

• Lead incident response efforts, including forensic analysis and recovery.

Risk Management & Compliance

• Conduct risk assessments to identify vulnerabilities and recommend mitigations.

• Ensure compliance with standards such as NERC CIP, ISO 27001, and corporate cybersecurity policies.

• Maintain thorough documentation of network configurations, security policies, and compliance audits.

System Maintenance & Disaster Recovery

• Perform regular system updates, patches, and lifecycle management (LCM).

• Manage backups and restorations for DCS and non-DCS systems.

• Oversee WSUS patching strategy and ensure continuity of updates across servers.

• Develop and maintain disaster recovery and business continuity plans.

Collaboration & Training

• Partner with engineering and IT teams to integrate cybersecurity into process control infrastructure.

• Provide training and awareness programs for employees on cybersecurity best practices.

• Act as a technical advisor for site leadership on emerging threats and security technologies.

What You’ll Bring

• Bachelor’s degree in Computer Science, Engineering, or a related field—or equivalent hands-on experience.

• 5+ years of experience in OT networking, cybersecurity, industrial controls, or a similar technical role.

• Strong knowledge of industrial control systems (ICS) and process control networks.

• Microsoft certification or equivalent IT administration expertise (critical for domain controller management).

• Hands-on experience with firewalls, IDS/IPS, VLANs, and network monitoring tools.

• Familiarity with compliance frameworks (NERC CIP, ISO 27001, etc.).
