How we know

It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.

Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Cylake, so its true age is longer.

Last checked Nov 3, 2026.

Some employers add pay only on their own site. Check the original posting before you rule it out.
