Robot Training Job Lifespans: How Long Listings Last

How it was measured

Daily reads, starting 12 Sep 2026, of the public job boards run by the robot training employers and programs this site follows. A single database query produces each figure for the window shown, and the live page and every monthly edition run that identical query. The note under each figure gives its base.

Listing date

The posting date the employer's job board shows, or, failing that, the first day the role turned up in the feed. A role that came in with an employer's back catalogue and carries no date has no known listing date.

Cohort

All roles with a known listing date posted in the 26 weeks up to the end of the period, none earlier than 14 Sep 2026 (when this site's index begins). Each employer's back catalogue, meaning whatever it already had up in its first week in this dataset, is left out.

Lifetime

Measured in hours and shown in days, from the listing date to the role's final sighting in its employer's feed. A role still up when the period ends has lived at least that long, so it is treated as censored rather than removed.

Still listed after N weeks

A Kaplan-Meier estimate of what share of roles remain in their feed N weeks past their listing date. Each role contributes for as long as it has been observed, which stops roles that are still up from passing for short-lived ones. If a role was first spotted more than two days after its listing date, it surfaced late and is counted only from the age at which it was spotted.

Median lifetime

The estimated age at which half of all roles have been taken down. If more than half are still up at the oldest age the data reaches, the median has not been reached yet.

Removed-only median

The familiar 'median days listed': days from posting to last sighting, for roles already taken down. Because it ignores roles still up (the longer-lived ones), it comes out shorter than the median lifetime.

Re-listed

A role that came down and later reappeared under the same title at the same employer inside the reposting window. That window comes from the gaps between a removal and the next listing with the same title, split into kinds (most removed roles never return): a gap counts while it is likelier to belong to the shortest kind, an employer putting the same role up again, than to any longer kind, a fresh opening that happens to share the title.

Evergreen role

A role still open when the period ends that is older than the age at which even the longest-lived kind of listing is more likely gone than up. The cohort's lifetimes are fitted as a mix of kinds, each with its own daily chance of coming down, and the cut-off is the first whole day t at which q to the power t is one half or less, q being the longest-lived kind's daily chance of staying up.

Weekly churn

Take the roles open at 00:00 UTC on Monday at employers followed before that week; churn is the share of them taken down by the end of the ISO week.

Kind of work

A role's title and description place it in one of the seven kinds of robot training work this site follows, ranging from robot teleoperation and demonstration collection through egocentric capture, embodied-AI annotation, robot evaluation and fleet operations to AV and drone operation. Each kind has a page of its own.

Window

Live page: roles posted in the 26 weeks to yesterday (UTC), none before 14 Sep 2026. Edition: roles posted in the 26 weeks to month end, none before 14 Sep 2026, followed up to that month end.

Limits of this data

• Hiring that happens without a public job board is not captured.
• A posting does not equal a hire, and a role that comes down may have been filled, put on hold or cancelled; employers do not say which.
• A brief listing life does not always mean a brief opening: some employers pull a role and repost it, or post one copy per city. The re-listing column flags where this happens.
• Feeds are read roughly once a day. A role that goes up and comes down between reads can be missed, and each removal is dated to the final read that still showed it.
• No estimate is made past the longest age the cohort has actually been watched, so while the dataset is young the later ages read n/a.
• When an employer pulls many roles at once (a project wraps up, a board gets reorganised), it shows up as one spike in weekly churn.

Collection and classification of listings are explained on the methodology page. Freshness, completeness and consistency are tested daily in the data quality report.

Monthly editions

The live page tracks each role listed in the 26 weeks up to yesterday (none earlier than 14 Sep 2026) and updates daily. Every finished month also gets its own edition, locked two days after month end, so a number quoted from it stays fixed.
