About Extend:

Extend is modernizing the $100 billion-per-year extended warranty and protection plan industry using cutting-edge technology, and top-notch customer service. After a $260M Series C financing round, we are ready to continue to scale our organization and grow beyond our $1.6B valuation.

Our API-first solution allows any merchant to offer extended warranties and protection plans, both online and offline, while also providing a merchant's end customers with a vastly improved and modern support experience that eliminates many of the issues customers face today with legacy underwriters.

  • Must be well organized, able to thrive in a fast-paced startup environment, must have the ability to approach problems with a collaborative, team-player attitude.
  • Strong communication skills in several mediums, working with a collaborative cross-functional team of peers and development teams throughout the company.
