• Design and deploy security solutions to protect OT systems, including firewalls, IDS/IPS, endpoint protection, and monitoring platforms
  
• Architect and implement OT DMZ environments and secure remote access solutions (VPN, MFA, jump hosts)
  
• Ensure secure integration between IT and OT systems while maintaining appropriate isolation and control
  
• Design, configure, and oversee OT network infrastructure including Cisco switches, routers, and wireless systems
  
• Manage firewall technologies (e.g., Fortinet, Palo Alto, WatchGuard) within OT environments
  
• Support hybrid infrastructure, including on-premise and cloud-based OT systems (e.g., AWS VPC environments)
  
• Optimize network performance, availability, and resiliency
  
• Collaborate with engineering and operations teams to integrate PLC, DCS, BMS, and SIS systems securely
  
• Support connectivity and cybersecurity for industrial protocols such as Modbus, DNP3, OPC UA, Ethernet/IP, and PROFINET
  
• Ensure secure deployment and operation of process historians and industrial data platforms
  
• Conduct OT risk assessments, threat modeling, and vulnerability management
  
• Ensure compliance with cybersecurity standards (NIST CSF, NIST SP 800-82, IEC 62443, ISO 27001)
  
• Support audit readiness, incident response planning, and disaster recovery initiatives
  
• Establish and manage process control network (PCN) domains and access controls
  
• Oversee implementation of monitoring tools (e.g., SIEM, Claroty, Nozomi) for threat detection
  
• Analyze and respond to security events, incidents, and anomalies
  
• Lead investigations and drive remediation efforts
  
• Work cross-functionally with IT, engineering, and operations to ensure alignment and secure integration
  
• Provide technical guidance and mentorship to OT analysts and engineers
  
• Engage with vendors and third parties to ensure secure and compliant solutions
  
• Stay current on emerging OT threats, technologies, and industry best practices
  
• Drive innovation and modernization initiatives within OT environments
  
• Assist in the development of training, procedures, and technical documentation
  

Qualifications

• Bachelor’s degree in Computer Science, Engineering, Information Technology, or a related field
  
• 3-5 years of experience designing and supporting OT/ICS network infrastructure and cybersecurity
  
• Strong experience with industrial OT network design and segmentation
  
• Hands-on expertise with Cisco networking (switches, routers, VLANs, routing protocols)
  
• Advanced experience with firewall administration and secure network architectures
  
• Experience with Windows Server environments, virtualization (Hyper-V/VMware), and Active Directory
  
• Familiarity with cloud networking (AWS VPC, EC2, S3)
  
• Deep understanding of OT cybersecurity frameworks and standards (NIST, IEC 62443, ISA, ISO)
  
• Experience with vulnerability management, intrusion detection, and incident response
  
• Proven experience implementing secure network zoning and access controls
  
• Experience with PLC, DCS, BMS, and SIS systems (e.g., Rockwell, Emerson, ABB, Honeywell)
  
• Familiarity with OT monitoring and asset management tools (e.g., Claroty, Nozomi)
  
• Experience supporting process historians (e.g., AVEVA PI, Canary) is an asset
  

Key Competencies

• Strong analytical and problem-solving skills
  
• Excellent communication skills with both technical and non-technical audiences
  
• Ability to lead complex technical initiatives and influence stakeholders
