Job Description

About Us

At Hiya we are on a mission to modernize voice with trust, identity, and intelligence. We're protecting everyday people from spam and fraud calls, connecting businesses with their customers, and helping carriers secure their networks for all. In 2015, Hiya founder Alex Algard saw the increasing need for innovation in the voice channel and began building the first caller ID and spam blocking apps for mobile while at Whitepages. In early 2016, Hiya spun out of Whitepages and brought its technology to market through Samsung Smart Call, the first-ever network-based spam solution with AT&T, and the Hiya consumer app. Three years later in 2019, we brought Hiya connect to market, a B2B branded call service that enables enterprise companies to connect to the consumers they are trying to reach. The combination of Protect, Connect, and the Hiya app  has resulted in the world's largest Voice Performance Platform with over 200M monthly active users.

We are headquartered in Seattle and have offices in London and Budapest.
