Hiring signal

Search results surfaced a Talent Systems and Recruiting Automation Lead (remote, but the posting lists San Francisco, New York, and Boston), Product Marketing - Agent Infrastructure (on-site, San Francisco), and Deployed Engineer (hybrid, Seattle). The listings were crawled about five months ago, so their availability on 2026-09-29 is unverified. Inferred: hiring is oriented toward U.S.-based candidates; the listings do not show an Africa-based opening.
