What competitor job postings tell you before any announcement does
A job post is a budget decision someone had to justify internally, published in public. It tells you what a competitor is about to do months before they announce it.
A company can say anything on its marketing site. It costs nothing.
A job post costs someone a headcount argument with finance, a salary band, and a hiring manager's time. Nobody opens a role for fun. And then, having fought for it internally, they publish it in public where you can read it.
It is the most honest document a competitor produces.
Read the volume
One job post is usually nothing. Somebody quit.
Three posts in the same function in the same month is a decision. Somebody sat in a room and said we are going to do this now, and this is what that decision looks like from outside.
Three sales roles means outbound. They are building a pipeline machine, and within a quarter your prospects are getting called by people with a script that mentions you. Two support hires means their volume finally broke the founders and they have a retention problem they are trying to fix. A cluster of engineers on one team means a build, and a big one.
Read the seniority
The level tells you the stage of the bet.
A first-ever hire in a function is the loudest single post there is. A company that has never had a marketing person and just posted for a head of marketing is starting something. That is a strategy change announced by accident.
A senior hire into an existing function usually means it is straining. Nobody hires a principal infrastructure engineer because things are going smoothly. They hire one because something is on fire or about to be.
A junior backfill is noise. Skip it.
Read the actual text
This is the part people forget, and it is where the roadmap sits in plain sight.
Job descriptions are written by hiring managers who are trying to attract candidates, which means they oversell. They name the interesting problems. They mention the unshipped thing to make the role sound exciting. They list the tools the team uses, the markets they are expanding into, the integrations they are building.
A back-end role that mentions experience with a payments provider they do not currently support is telling you they are about to support it. A role based in a country they do not operate in is telling you where they are going.
Read the requirements list like a leaked roadmap, because that is functionally what it is.
Read the silence
What they stopped hiring for matters too.
A competitor who was hiring aggressively across three teams and has now posted nothing for four months is either out of money or in a freeze. Either way, they are not the threat they were, and you can stop worrying about them for a while.
The careers page is the only place a company tells you the truth about its priorities on a monthly cadence, in public, for free. Almost nobody reads it.
