An old date is not proof a role is stale: some platforms keep a role open to build a pool, or keep its original date when they refresh it.

Added against closed

Since 20 October 2026, on the platforms we were already reading, 134 roles were added and 166 closed: 32 more closed than added. Our record of individual roles is only a day long so far, so this widens into a full week as days pass.

Platforms we began reading in this period, so their existing roles aren't counted as new: 10x Team (126), Aptura (26), HumanSignal (34), Jobgether (16), JT AI Labs (144), Lifted, an Upwork Company (47), Lilt (375), Lionbridge AI Data Training (50), Perle (64), TELUS Digital AI Community (14), TSMG (160).

These figures show what changed on the boards, not how many people were hired or how many vacancies were cancelled.

Reposts

We haven't seen any role closed and then listed again under the same title yet. We keep a record of every role's title from 20 October 2026, so reposts will show here as they happen.

Entry level

Of the 3,176 open roles tagged with a level, 516 (16%) are entry level. 200 roles (4% of all open roles) say no experience is needed: see them.

  1. Entry level 16% of tagged roles
    516
  2. Mid level 24% of tagged roles
    747
  3. Senior 19% of tagged roles
    615
  4. Expert / credentialed 41% of tagged roles
    1,298

1,532 roles state no level, so they are left out of the split.

How we count

  • Age: the posting date the platform gives. Roles with no date, talent pools and paid studies are left out of the age figures.
  • Added and closed: a role is added the first time we see it and closed when it leaves the platform's board. A platform's first day is treated as its backlog. We record this from 20 October 2026.
  • Reposts: same platform, same title once case and punctuation are ignored, listed at least three hours after the earlier role closed.
  • Levels: the level stated or inferred from each posting. Many postings state none.
  • Limits: this is what platforms publish. It says nothing about whether anyone was hired. Full methodology.

The AI training job market: common questions

How old are AI training job listings?

Among the 4,085 open roles with a posting date from their platform, 62% have been up for 60 days or more, and the median is 132 days. Dates are as the platform gives them, and some platforms keep the original date when they refresh a role, so an old date doesn't always mean an untouched listing.

Does an old listing mean the role is filled?

No. Some platforms keep roles open for months to build a pool of people, and others leave a listing up after the first hires. We check every role against the platform's own board every hour, so a role we list was still on the board at the last check.

What counts as a role being added or closed?

A role counts as added the first time we see it on a platform's board, and as closed when it leaves. That shows what changed on the boards, not how many people were hired. The first day we read a platform is its backlog, so it is not counted as new.

What is a repost?

An open role with the same title as one the same platform closed at least three hours earlier. It can be a genuine refresh, a role that was paused, or the same project listed again.

Are there entry-level AI training jobs?

516 open roles are tagged entry level (16% of those with a level), and 200 (4% of all open roles) say no experience is needed. See the no-experience page for the list.
