The control plane needs builders

The infrastructure of the next decade will look fundamentally different from the last one. Build it alongside the engineers who wrote FreeSWITCH.

What you'd be working on

Define a category, not only a product

The team has been building real-time communications infrastructure for nearly two decades and is now building the programmable layer on top. You'll work close to a real product, built by people who deeply understand it, in a category we're actively defining.

Voice AI agents

Agents that run natively inside the media engine.

One surface, any language

Python, Node, Go, and Ruby share one declarative API.

The programmable layer: SWML

You'll turn complex call logic into clean, readable code.
