Photonics Engineer (Mid-Level) vs Railway Signalling Engineer (Mid-Level)
How do Photonics Engineer (Mid-Level) and Railway Signalling Engineer (Mid-Level) compare on AI displacement risk? Photonics Engineer (Mid-Level) scores 46.8/100 (YELLOW (Urgent)) while Railway Signalling Engineer (Mid-Level) scores 76.1/100 (GREEN (Transforming)). Here's the full breakdown.
Photonics Engineer (Mid-Level): Niche but growing demand from silicon photonics, LiDAR, telecom transceivers, and AI datacentre interconnects protects this role from immediate displacement, but 65% of task time faces meaningful AI augmentation as AI-enhanced photonic simulation, inverse design, and automated test analysis mature. Adapt within 3-7 years.
Railway Signalling Engineer (Mid-Level): Acute skills shortage, safety-critical accountability, and physical trackside work in unstructured environments make this one of the most AI-resistant engineering roles. ETCS/ERTMS rollout creates structural demand growth for decades. Safe for 10+ years.

Sub-Score Breakdown
Railway Signalling Engineer (Mid-Level) wins 4 of 5 dimensions — stronger on Task Resistance, Evidence Calibration, Barriers to Entry, Protective Principles.
| Dimension | Photonics Engineer (Mid-Level) | Railway Signalling Engineer (Mid-Level) |
|---|---|---|
| Task Resistance (/5) | 3.3 | 3.9 |
| Evidence Calibration (/10) | 4 | 9 |
| Barriers to Entry (/10) | 3 | 9 |
| Protective Principles (/9) | 4 | 7 |
| AI Growth Correlation (/2) | 1 | 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). For full individual assessments, see the Photonics Engineer (Mid-Level) and Railway Signalling Engineer (Mid-Level) role pages.
