Two things are true at once here and they are easy to confuse. The demand is unambiguous — AI specialist postings grew nearly eight times as fast as the overall jobs market in 2025, and the skills premium is real at 62%.PwC 2026
The role, though, is not research. It is production engineering with models in it: retrieval pipelines, evaluation, chasing drift, deciding when an output is reliable enough to ship.

- Every AI deployment creates maintenance and monitoring obligations
What threatens it
- Titles age fast in this space — the same work was 'ML engineer' five years ago
- A crowded on-ramp: it demands production engineering skill, not curiosity
