OT/ICS Security Engineer (Mid-Level) vs PKI Engineer (Mid-Level)
How do OT/ICS Security Engineer (Mid-Level) and PKI Engineer (Mid-Level) compare on AI displacement risk? OT/ICS Security Engineer (Mid-Level) scores 73.3/100 (GREEN (Transforming)) while PKI Engineer (Mid-Level) scores 43.6/100 (YELLOW (Urgent)). 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.
PKI Engineer (Mid-Level): Certificate lifecycle automation is accelerating fast — 47-day TLS lifetimes by 2029 will eliminate manual certificate operations entirely. The surviving PKI engineer is the one who designs and architects PKI infrastructure, not the one who issues and renews certificates. Transform within 2-5 years.

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 PKI Engineer (Mid-Level) role pages.
