Hopper Software Engineer in Cambridge, Massachusetts

Hopper is a mobile-only company that uses big data to predict and analyze airfare and accommodations. The app provides travelers with the information they need to get the best deals on flights and hotels, and notifies them when prices are at their predicted lowest points.

Since launching in 2015, Hopper has become one of the fastest growing travel apps ever with over 20 million installs. It is the #1 travel app in over 37 countries and ranks as one of the top 10 travel apps in over 95 countries. Our users have watched 45 million trips since launch and are booking $1.5 million worth of travel through the app each day. Hopper has received accolades such as Apple’s App Store Best of 2015, the Google Play Award for Standout Startup of 2016, and the Webby Award for Best Travel app.

Hopper was founded in 2007 and has $104 million CAD in funding to date from Caisse de dépôt et placement du Québec (CDPQ), Accomplice, Brightspark, OMERS, BDC IT Venture Fund, and Investissement Québec.
