## About the role

Our customers are founders and GTM leaders who have handed us their pipeline. When something breaks, or a sequence doesn't behave the way they expected, or they need a field we don't support yet, they say so in a shared Slack channel — and how fast we turn that around is most of what determines whether they stay.

## What they're looking for

- Own first response in customer Slack channels — reproduce, diagnose, and give a real answer, fast
- Ship fixes directly: bugs on live campaigns, data and enrichment issues, sequence and sender misconfigurations, backfills, one-off scripts
- Decide what's a same-day fix versus what needs a spec, and write the spec when it's the latter
- Join onboarding and weekly check-in calls, unblock customers live rather than taking notes
- Build the internal tooling that makes the next fix faster — admin views, replay and debugging tools, health checks that catch problems before the customer does
- Turn recurring friction into evidence-backed tickets so the product stops generating the same requests
