Cyber SDC - OT - Security Architect

External Role Description

PRACTICE DESCRIPTION

Organizations operating industrial and operational technology environments require consistent application of cybersecurity standards, secure connectivity patterns, network segmentation practices, and operational support requirements across diverse site environments.

The Security Architect – OT role provides architecture guidance, design validation, and technical advisory support to help ensure OT environments are implemented and operated in alignment with established security requirements and approved design patterns.

JOB SUMMARY

We are seeking an experienced Security Architect – Operational Technology (OT) to provide architecture guidance and technical oversight for industrial, manufacturing, laboratory, and operational technology environments.

This role supports site-level design reviews, network segmentation validation, secure connectivity planning, exception analysis, operational readiness, and risk-based technical decision-making. The architect works across cybersecurity, infrastructure, engineering, operations, and site teams to help ensure OT solutions are secure, supportable, and aligned to established standards.

Role positioning: This role applies and interprets established architecture standards rather than defining enterprise standards or performing routine day-to-day governance queue execution.

KEY RESPONSIBILITIES

Architecture Standards Adherence

• Apply established OT cybersecurity standards and approved design patterns to site-level implementations.
• Review proposed OT network, firewall, secure access, monitoring, and infrastructure designs for alignment with approved standards.
• Identify gaps between proposed implementations and established architecture requirements.
• Recommend practical remediation options for design constraints, exceptions, or operational support concerns.

Site-Level Design Review and Validation

• Support architecture reviews for site implementations, modernization activities, and operational changes.
• Validate alignment with segmentation, zoning, firewall, remote access, monitoring, and operational support expectations.
• Participate in design discussions for complex, high-risk, or non-standard OT implementations.
• Partner with engineering and operations teams to support transition of approved designs into steady-state support.

Risk and Exception Support

• Support technical risk assessments and impact analysis for non-standard architecture decisions.
• Provide technical input for exception reviews, risk acceptance discussions, and remediation planning.
• Escalate material design risks, control gaps, or operational concerns through appropriate governance channels.
• Ensure architecture decisions and risk outcomes are documented and supportable.

Secure Connectivity and Infrastructure Alignment

• Review secure connectivity patterns involving firewalls, remote access, segmentation controls, monitoring platforms, and related infrastructure.
• Support alignment of applicable Zero Trust principles to OT users, devices, applications, and remote access use cases.
• Advise on technical dependencies that may affect implementation, operations, lifecycle management, or supportability.
