Key findings

  1. 1

    Scale AI had the most open staff roles on 11 Nov 2026 (169), then Mercor (90) and Handshake (77).

    Figure 1
  2. 2

    Engineering and product is the largest function in vendor hiring: 167 roles, 25.5% of all open staff roles.

    Figure 2
  3. 3

    4 vendor roles are in data acquisition and partnerships, at Scale AI, Handshake, Snorkel AI and AfterQuery.

    Figure 3
  4. 4

    113 roles are in research, evals and RL environments (17.3%), at 13 vendors.

Sample. 655 staff roles open on the public boards of 14 human-data vendors on 11 Nov 2026; shares are of each vendor's own open roles.

Staff roles only: the expert and contractor roles vendors recruit for are counted in this site's other reports, from their job feeds.

Some vendors keep a single evergreen posting per team, so open roles measure hiring intent, not headcount.

For labs, data vendors and researchers

Buy the data behind this report

The figures above are a summary. Behind them are records we collect ourselves, every day:

  • 0 roles tracked, each with its history

    Every role on 0 job boards, read since n/a (every hour since 18 Oct 2026): its pay and place, and the first and last day it was open.

  • 0 apply clicks in 28 days

    Which roles people actually apply to, by field, pay and kind of work. It happens on this site, so nobody else can count it.

  • 39 lab and vendor hiring boards

    The job boards of 25 AI labs and 14 human-data vendors, read every day: who is hiring for human data, and who is hiring to buy it.

What you can buy

  • The records

    The rows behind any figure, with their history, not only the totals.

  • A regular feed

    The same figures every week or month, as files.

  • A custom cut or benchmark

    Your countries, languages or fields, or your own platform against the market.

Building AI and need the experts behind this data? (you contract them yourself) or (we deliver the expert work).

Investing in AI-data companies? Hiring radar is these records role by role, every day, as files.

Method and definitions

The public job boards (Greenhouse and Ashby APIs) of AI labs and human-data vendors, read every day. Every figure is computed by one database query over the window shown, the same query for the live report and for every edition. Each figure states its sample beneath it.

Staff role
A role a vendor posts for its own team; the expert and contractor roles it recruits for are counted in the job-feed reports instead.
Function
The first of the published function patterns a role's title (or team) matches: data acquisition and partnerships, expert supply, expert and contractor roles, research and RL environments, delivery, sales, engineering, corporate.
Window
A reading of every board today; no monthly editions.

What this data cannot tell you

  • Labs without a public board API (Meta, Microsoft, Apple, Amazon, Nvidia, Google DeepMind's own careers site) cannot be read, so their hiring is not counted.
  • An open role is hiring intent, not headcount: some companies keep one evergreen posting per team, others post one per location.
  • A role counts by its title and team against published patterns; a role described only in its text is not counted.

How the job feeds are read and roles are classified: site methodology. How fresh, complete and consistent the data is, checked every day: data quality and coverage.

Editions

This report reads the live job boards every day. Past boards cannot be read again, so it has no monthly editions: download the data to keep a dated copy.
