Sr Engineer - BizApps (Pacific time zone preferred)

8x8 connects our customers and teams globally, empowering CX leaders with performance and insights to make smarter decisions, delight customers, and drive lasting business impact. We're looking for a Senior Engineer in the Pacific time zone of the US (fully remote) who leads with strong programming fundamentals and uses AI to move fast across any technology.
