Founding Growth Engineer

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 6 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. 

Outcomes

1. Own and execute growth experiments
   1. Present a 20-page PDF with all the sources of growth, all the conversion of all the steps in the first 7 days
   2. Ruthlessly prioritize, design, and implement experiments that focus on optimizing conversion rates, user engagement, and retention in the first 14 days
   3. Ship a growth feature/experiment within the first 30 days (e.g., creating and testing onboarding flows to increase user activation, landing page A/B test, etc)
2. Optimize Funnel Performance:
   1. Ship optimizations and refactors to improve customer acquisition and retention metrics
   2. Within the first 14 days, ship a pre-scoped conversion rate optimization (e.g., decreasing drop-off at key funnel points)
   3. Independently ship a significant experiment optimization within the first 30 days (e.g., automated user segmentation for personalized email campaigns)
3. Use Data to Drive Decisions:
   1. Collect and analyze data from growth experiments, iterating quickly based on results
   2. Build dashboards and tools to track real-time performance of growth initiatives
   3. Present key insights and learnings from experiments to the founding team within the first 30 days

• Proficiency in coding and data analysis (e.g., SQL, Python, or other relevant technologies)
• Experience building and automating growth experiments in fast-paced startup environments
• A proven track record of improving key growth metrics through technical experimentation and optimization
• Ability to balance creative growth ideas with analytical, data-driven decision-making
