Building Services Engineer — Chartered (Mid-Level) vs ERTMS Systems Engineer (Mid-Level)
How do Building Services Engineer — Chartered (Mid-Level) and ERTMS Systems Engineer (Mid-Level) compare on AI displacement risk? Building Services Engineer — Chartered (Mid-Level) scores 48.1/100 (GREEN (Transforming)) while ERTMS Systems Engineer (Mid-Level) scores 62.0/100 (GREEN (Transforming)). Here's the full breakdown.
Building Services Engineer — Chartered (Mid-Level): CIBSE chartership, multi-discipline design authority, physical commissioning, and Building Regulations compliance protect this role. AI is accelerating calculations and BIM production, but engineering judgment across HVAC, electrical, plumbing, fire protection, and lighting systems in complex buildings remains firmly human. Safe for 5+ years, but daily workflows are shifting significantly.
ERTMS Systems Engineer (Mid-Level): Safety-critical ETCS accountability, physical trackside commissioning, and EU-mandated digital railway migration make this a strongly protected engineering specialism. Safe for 10+ years.

| Protective Principles (/9) | 5 | 6 |
| AI Growth Correlation (/2) | 0 | 1 |
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).
