This role ensures issues are triaged, resolved, or escalated cleanly within SLA while strengthening our support infrastructure over time.

60 Day:

• Own front-line enterprise ticket triage with a focus on resolving most tickets within 30 minutes.

• Contribute to SLA automation initiatives (Tasker, Slack bots, routing improvements).

• Strengthen documentation to reduce repeat issues and increase team velocity.

4+ years in technical support, support engineering, or customer-facing technical roles at a SaaS or API-first company.
