Act as the primary technical escalation point for customer support issues related to API usage, model behavior, performance, and reliability.. Troubleshoot complex technical problems across the full request lifecycle (client → API → model provider → response)..

Communicate clearly and calmly with customers during incidents, including status updates and resolution summaries.. Help customers understand platform behavior, limitations, and best practices.. Contribute to support documentation, troubleshooting guides, and internal playbooks..

Calm, structured communicator in high-pressure or incident scenarios.. Comfortable working directly with customers on technical issues without overpromising.. Highly organized and able to manage multiple support threads and escalations in parallel.. Strong written and verbal communication skills (Slack-first, async clarity)..
