Founding Growth Engineer

Company Overview

Apple 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 a Series A from a top-tier firm this past week. We’re a small team of 17 and growing. We're building out the founding team in-person in SF to scale what’s working.

Mission

The Founding Growth Manager will be a driving force behind building, running, and analyzing growth experiments aimed at rapidly scaling user acquisition, engagement, and retention. You'll play a critical role in optimizing our product funnels, refining customer onboarding, and improving overall growth metrics through a combination of technical experimentation, data analysis, and automation. You’ll also be a foundational part of how we build the culture at Vapi.
