Five9 is a leading provider of cloud software for the enterprise contact center market, bringing the power of the cloud to thousands of customers and facilitating more than three billion customer interactions annually. Five9 has led the cloud revolution in contact centers, helping organizations transition from legacy premise-based solutions to the cloud. The cloud contact center market has become the hot space for innovation in real-time communications, and is the tip of the spear for the application of Artificial Intelligence. Five9 has led the charge with its Genius AI platform. Five9 offers a high-energy environment with lots of room for personal and professional growth. Our innovative AI team is seeking a talented and experienced Senior Full Stack Software Engineer to join our Voice of Customer (VOC) team.

An ideal candidate for us is an experienced engineer who is passionate about building high performance web platforms and applications, a brilliant problem solver and a creative self-starter.
Voice of Customer (VOC) is Five9’s AI-powered customer insights product. Every day, contact centers handle enormous volumes of voice and chat conversations that hold the clearest signal about what customers actually want - and almost none of it gets read. VOC applies AI to those conversations at scale to surface why customers are reaching out, how those reasons cluster and shift over time, and where the business should act. The result is a set of insights and analytics that CX and operations leaders use to make decisions, with the ability to trace any insight back to the conversations behind it.
