Remote Index

ReqHunt Remote Index — location data incomplete for this company. How the ReqHunt Remote Index works — the four bands, the 10-role floor, why hybrid is excluded, and why companies with incomplete location data are withheld rather than scored low.

Read straight from Horizon3's careers page (ashby), tracked since August 2026. Refreshed every hour. Posting dates come from the company's own applicant tracking system, not from when ReqHunt first saw the role. “No longer listed” means the role has left the company's careers feed. That can mean filled, cancelled or withdrawn — the feed does not say which.
