Pizza Delivery Driver (Entry-to-Mid) vs Signalling Tester In Charge / STIC (Mid-Level)
How do Pizza Delivery Driver (Entry-to-Mid) and Signalling Tester In Charge / STIC (Mid-Level) compare on AI displacement risk? Pizza Delivery Driver (Entry-to-Mid) scores 27.7/100 (YELLOW (Urgent)) while Signalling Tester In Charge / STIC (Mid-Level) scores 87.7/100 (GREEN (Stable)). Here's the full breakdown.
Pizza Delivery Driver (Entry-to-Mid): Pizza delivery drivers face a dual reality: strong near-term demand from food delivery growth, but autonomous delivery robots (Nuro, Starship, Serve) are targeting the same short-radius, standardised-product deliveries. With 55% of task time scoring 3+ and only 2 points above the Red boundary, adapt within 3-5 years.
Signalling Tester In Charge / STIC (Mid-Level): Safety-critical physical testing in unstructured trackside environments, IRSE licensing, and personal go/no-go certification authority make this one of the most AI-resistant roles in rail engineering. Acute skills shortage and ETCS rollout sustain structural demand for decades. Safe for 15+ 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).
