About the role Skills: JavaScript, Kubernetes, Node.js, Rust, TypeScript, Distributed SystemsCompany OverviewApple Intelligence and Google Gemini are about to onboard 4 billion people to voice assistants that actually talk like people.
This marks a new beginning for voice as the world's default interface.
We will all want voice everywhere.
Businesses are not ready.
Products are not ready.
We're building the infrastructure that helps developers close the gap between the raw model and voice AI in production.
Give it a try here. We launched in March, scaled revenue, and raised this past week.
We're a small team of 6 and growing.
We're building out the founding team in-person in SF to scale what's working.
