About the job
Meet siena
Siena is the Agent of Record for CX, built for consumer brands like Spanx, FIGS, Brooklinen, and Grüns.
It runs as a connected multi-agent stack on top of a shared intelligence layer: agents that sell, support, listen, handle social and voice across the entire customer journey, turning every conversation into signal you can act on.
The team
We are a small, fully distributed, global team. We have built leverage into how we work, which is what lets a team this size move at the speed we do.
We hire athletes. Everyone here owns real outcomes, defaults to writing over meetings, communicates with directness, and acts the moment they see something worth acting on. Low ego, high standards, fast clock.
If you want to set the bar rather than follow one, keep reading.
The role
You take the hardest problems customers hit in production and solve them end to end: a webhook that stopped firing, an agent filling the wrong parameter, a report that won't reconcile. You find the real cause, work the customer to resolution, then build the automation so it doesn't come back. This is the front door to deployment and platform work at Siena, with a clear path into Forward Deployed Engineering or deeper platform work.
