KAYAK

KAYAK is a travel metasearch engine, founded in 2004, that scans hundreds of travel sites simultaneously so that travelers can compare flights, hotels, rental cars and vacation packages in one place, with transparent pricing and no hidden fees. The platform processes billions of searches annually for millions of leisure and business travelers worldwide.

Technical work at KAYAK spans travel metasearch technology and large-scale search processing, alongside newer AI-powered search tools. These include KAYAK.ai, which helps travelers find suitable travel options in seconds, and a conversational search experience built on the same AI foundations. Engineering teams work on search systems operating at the scale of billions of queries per year across hundreds of sources.

The company employs over 800 people across 15 international offices and manages seven travel search brands globally. It operates a flexible hybrid work model supporting both in-office and remote work. KAYAK describes itself as founded for travelers, by travelers, and states values of boldness, ownership and winning together, with an emphasis on transparency and confidence for users.
