Summary: The OT Technical Architect is responsible for designing and defining secure operational technology architectures that align with business, safety, and operational constraints in industrial environments. This role involves leading design strategies, collaborating with cybersecurity teams, and developing secure reference architectures while ensuring compliance with relevant standards. The architect will also provide guidance to various teams and support the implementation of OT security technologies. Strong communication skills and extensive experience in networking within OT/ICS environments are essential for success in this position.

Key Responsibilities:

  • Lead design strategy and OT architecture across large groups and initiatives
  • Define, bridge, and communicate the direction of OT target-state cybersecurity architectures
  • Partner with Cyber teams to align OT architecture strategy with overall cyber roadmap
  • Act as the main resource lead for OT Security Analyst support
  • Design strategy for visibility, secure remote access, segmentation, zoning, and conduit models per IEC 62443, NIST SP 800-82r3
  • Develop and publish secure reference architectures for manufacturing sites, remote access, and other OT security needs
  • Support, evaluate, select, and implement OT security technologies
  • Lead OT cybersecurity design reviews and technical security requirements
  • Provide OT architectural guidance to engineering teams, system integrators, IT, MFG-IT teams, and cybersecurity teams
  • Translate cybersecurity requirements into implementable designs aligned with the OT cybersecurity strategy
  • Support M&A or greenfield OT security architectures across domestic/international MFG discussions and projects
  • Participate in and support OT tabletop exercises as needed
  • Align OT security architecture to controls from IEC 62443, NIST SP800-82r3, CISv8, NIST CSF
  • Communicate and share updates with leadership

Key Skills:

  • 7-12+ years in Networking with OT/ICS environments
  • Strong architecture experience across industrial networks, OT DMZ design, secure remote access, OT monitoring platforms, networking, routing & switching concepts, network & security architecture design, and segmentation
  • Deep knowledge of IEC 62443, NIST SP800-82r3, NIST CSF, CISv8, Purdue Model, OSI, TCPIP Model, and Zero Trust concepts applied to OT
  • Ability to balance workload, safety, availability, and security
