SignalsAPI AI-Engineering Demand Cut
How employer demand splits across the engineering specialisms — one filtered cut of the corpus per specialism, ranked by deduplicated posting volume.
224,285
deduplicated postings in the last 7 days (-7.3% vs the prior period, 241,890)
AI and machine-learning roles are advertised alongside — not instead of — the data and platform work that puts them into production, so demand for the surrounding specialisms moves with them rather than against them.
SignalsAPI AI-Engineering Demand Cut: demand by cut, October 2026
| Cut | Postings |
|---|---|
| Platform & reliability | 893 |
| AI & machine learning | 734 |
| Data engineering | 604 |
| Data science | 514 |
| Security engineering | 443 |
Methods Box
Every figure below is a count of deduplicated postings — one row per company, job title and country, per the rule below — over the stated window.
We measure the volume of online job postings we observe, deduplicated to one row per company, job title and country, across 47 distinct sources, over a rolling 30-day window.
Repeat and re-posted advertisements collapse to a single row per (company, job title, country). Where several postings share that key, we keep the most complete one — the row that resolves to a named company with an industry, headcount and location — and break remaining ties by the most recent posting date. Note the key is country, not city: two postings for the same role in two cities of one country count once, and the same role in two countries counts twice.
No published cell describes fewer than 5 distinct companies.
What it does not measure:
- Employment levels, hires, or separations. This is a posting-volume measure, not an establishment survey — it is not comparable to, and does not estimate, the figures BLS publishes.
- Vacancies that are never posted online, filled internally, or filled through a network without a public advertisement.
- Postings behind a login, a paywall, or an application flow we do not crawl.
