OT/ICS Security Engineer (Mid-Level) vs Senior Security Architect (Senior)
How do OT/ICS Security Engineer (Mid-Level) and Senior Security Architect (Senior) compare on AI displacement risk? OT/ICS Security Engineer (Mid-Level) scores 73.3/100 (GREEN (Transforming)) while Senior Security Architect (Senior) scores 67.8/100 (GREEN (Transforming)). Here's the full breakdown.
OT/ICS Security Engineer (Mid-Level): OT/ICS security is one of the most AI-resistant cybersecurity specialisms due to physical presence requirements, safety-critical liability, and the absence of viable AI tools for proprietary industrial protocols. Safe for 5+ years with significant daily work transformation.
Senior Security Architect (Senior): The Senior Security Architect role is protected by team leadership responsibilities, cross-domain design judgment, and accountability for security outcomes — but AI is transforming daily work by compressing threat modelling, compliance mapping, and architectural documentation. 7-10+ year horizon.

What Do These Scores Mean?
Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk). For full individual assessments, see the OT/ICS Security Engineer (Mid-Level) and Senior Security Architect (Senior) role pages.
