Position Overview:

We are seeking a highly skilled and adaptive IT/OT Systems Architect to bridge the gap between traditional IT practices and operational technology (OT) used in industrial control networks. This role is instrumental in designing secure, scalable, and efficient project- specific OT network architectures, while aligning with company-wide cybersecurity and infrastructure best practices. The ideal candidate will have strong foundational IT skills with a keen understanding (or willingness to rapidly acquire) expertise in control system protocols, industrial networking, and emerging technologies.

Key Responsibilities:

• • Develop and maintain best practices for OT networks across all projects and facilities.
  • Select and standardize the company’s industrial network switch hardware and configuration templates.
  • Design OT network architectures for customer and internal projects, including proper subnetting, VLANs, and segmentation strategies.

  • Collaborate closely with internal IT teams, ensuring alignment and compliance with broader cybersecurity goals and corporate standards.
  • Stand up and maintain project-based servers, virtual or physical, in both Windows and Linux environments.
  • Evaluate and implement technologies like Raspberry Pi, industrial PCs, or other edge compute devices for project deployment.
  • Ensure systems follow and/or achieve cybersecurity frameworks and certifications relevant to industrial systems (e.g., IEC 62443, NIST, etc.).
  • Acquire or maintain relevant cybersecurity certifications (e.g., CISSP, GICSP, CompTIA Security+, or equivalent).
  • Implement and support industrial communication protocols and technologies, including: BACnet/IP, Modbus TCP, MQTT, RESTful APIs, Kubernetes (K8s).

Qualifications: 

• Bachelor’s degree in Computer Science, Information Technology, Cybersecurity, or related field (or equivalent experience)
• 5+ years of hands-on experience in IT infrastructure, network design, and/or cybersecurity
• Working knowledge of both enterprise IT and industrial control systems
• Familiarity with network security concepts, VPNs, VLANs, firewall rules, and network segmentation
• Strong experience with Windows Server, Linux, Docker, and virtualization platforms
• Excellent communication and documentation skills 

Preferred Skills:

• • • Experience with IEC 62443, NIST SP 800-82, or other industrial security frameworks
    • Certifications such as: CISSP, GICSP, CCNA/CCNP, Security+, AWS/GCP cloud certs
    • Experience with automation, SCADA, BMS, or building systems integration
    • Familiarity with scripting (Python, Bash, PowerShell) and modern infrastructure tools (Terraform, Ansible, etc.)
