Why job requirements

A website scanner sees the scripts on a homepage: analytics, a chat widget, a CDN. Job requirements show what the engineering and data teams work with every day (the warehouse, the orchestration, the languages) and which teams are growing around it. A company's own products are left out of its stack, and so are staffing agencies and job republishers.
