Own front-line support via Zendesk/email/phone—respond fast, meet SLAs, and keep customers informed. Triage and resolve L1/L2 issues across web apps, devices, and integrations; capture logs and write clear updates. Escalate to Engineering with crisp repro steps and environment details; drive issues to verified closure. Keep the knowledge base current—articles, macros, and runbooks that boost self-service. Track queue health (backlog, reopen rate, CSAT), spot trends, and coordinate with Ops on RMAs when needed. Participate in a light rotation for priority incident coverage during business hours and after-hours escalation.
