How these numbers are calculated
NearSkill lists 204 live roles for STEM researchers and PhDs, grouped into 190 role families. Of the 173 USD hourly listings, the median advertised rate is $85/hr. The middle 50% sits between $50 and $100/hr, and the full posted range is $7 to $250/hr. These are advertised rates, not earnings.
The largest sources in this set are micro1 (59), AfterQuery (40), Handshake AI (31), Mercor (24). The skills that appear most often are python, ai evaluation, llm evaluation, technical writing, english. 100% of this set is remote.
Eligibility is mixed: 64 listings publish country eligibility explicitly, 0 imply it in the description, 81 do not state it. 59 listings are marked worldwide. Missing eligibility is treated as unknown, not as worldwide.
Figures were computed from the live job feed on November 15, 2026. Counts and pay move as listings are added or closed. NearSkill does not estimate missing pay, and non-USD rates are excluded from the USD medians rather than converted.
Questions, answered
How many roles are live for STEM researchers and PhDs?
204 active listings on November 15, 2026, grouped into 190 role families. Near-identical language or region variants are grouped so one employer cannot fill the list.
What is the median advertised pay?
$85/hr from 173 USD hourly listings. The middle 50% runs from $50 to $100/hr. It is advertised pay, not earnings, and missing pay is not estimated.
Which platforms have the most roles?
micro1 leads with 59 listings, followed by AfterQuery (40), Handshake AI (31), Mercor (24).
Are these roles remote?
100% of this set is remote. Remote describes the work arrangement; it does not guarantee that the employer accepts applicants from every country.
How is country eligibility determined?
Eligibility comes from the listing's country field when it is present, or from explicit eligibility language in the description. 81 listings in this set do not state it, and those are treated as unknown rather than worldwide.
