This page gets better with age. It is built from a daily record that started the day we began watching Arbor Energy. Every day it runs, there is more history here that cannot be reconstructed from anywhere else — because the original posts are deleted.
Job posts get deleted. We keep them.
FirstIn watches company job boards at the source and tells you the moment a role opens — and keeps the record after it's taken down, so you can see what really happened to a team's hiring.
