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.

As a Senior Technical Support Engineer, you will join our global Tier 2 Technical Support organization, providing advanced technical expertise for our cloud communications platform.

For our certified partners, you will serve as the primary technical point of contact. Because our partners are trained and certified to perform Tier 1 troubleshooting, you will engage directly on advanced technical cases, helping them resolve challenging issues while delivering an exceptional support experience.
