- Leverage AI assistants as investigative aids while validating their output against real data.
- Collaborate across Slack channels, knowledge bases, and multiple product teams to gather evidence.
- Escalate issues only after thorough diagnostics and documentation for the next support tier.
Required profile

- Strong judgment under uncertainty and ability to work independently without heavy manager guidance.
- Enjoys tackling the hardest problems rather than routine, scripted tickets.

- REST APIs
- JSON
- HTTP status codes
- Command‑line interface
