In this role you will… Own complex cases end-to-end: integrations, APIs, data issues, multi-module configuration — to Earned Resolution, not ticket closure. Deliver Pro Desk as the primary expert: scheduled 1:1 session that replace CSM coaching with certified product expertise. Take escalated Live Chat and voice — real-time expertise when the customer’s business is stuck. Reproduce and evidence defects: clean repro steps, logs, and breadth data that feed EIM scoring and the OneList.

Work AI-in-the-loop as default: copilot research, drafted responses reviewed, knowledge gaps closed. Pod Specialist certification within 45 days; multi-product breadth valued. You've got what it takes if you have… 3+ years technical support with real troubleshooting depth — logs, APIs, SSO, integrations, data flows. Experience troubleshooting SSO, authentication, user provisioning, and identity management solutions. Working knowledge of SAML, OAuth, SCIM, OpenID Connect, and identity providers such as Microsoft Entra ID, Okta, or similar platforms. Hands-on experience troubleshooting REST APIs, web services, webhooks, connectors, and integration workflows.
