Job Postings and Hiring Signals

Companies post open roles publicly, on their own career pages and on aggregators, well before those hires show up in a headcount line of a quarterly filing. Vendors scrape these postings over time and turn the raw counts into a signal: a company rapidly increasing its open engineering roles is plausibly gearing up for a product push or expansion, while a company quietly freezing new postings or pulling listings down may be pulling back before that shows up anywhere in official numbers.

The appeal is the lag: hiring intentions are set months before headcount, capital expenditure, or revenue guidance reflect them, so a job-postings signal can front-run those slower-moving fundamentals. The catch is noise and interpretation — postings can reflect routine churn replacement rather than growth, a large company can post generic listings across many locations for a handful of actual openings, and postings data is easy to game or distort by a company's own recruiting strategy, so the raw count needs care (deduplication, normalizing for company size, distinguishing net-new roles from backfills) before it's a usable signal rather than noise.
