Founding Senior Engineer (Backend)

Vapi is revolutionizing the voice AI landscape as Apple Intelligence and Google Gemini prepare to bring advanced voice assistants to 4 billion people. As a recently launched startup that has already secured Series A funding, Vapi is building crucial infrastructure to help developers bridge the gap between raw models and production-ready voice AI solutions.

The Founding Senior Engineer (Backend) role offers a unique opportunity to join a small but growing team of 17 people, working directly in San Francisco. You'll be instrumental in building and scaling the company's modular API-first architecture, focusing on real-time, low-latency solutions that delight customers.

This role combines technical excellence with entrepreneurial spirit, requiring someone who can not only architect and implement complex backend systems but also communicate effectively with customers and help shape company culture. The ideal candidate brings both senior-level engineering expertise and the mindset of a founder, capable of taking ownership of features from conception to deployment.

Working at Vapi means being at the forefront of voice AI technology, with the chance to make a significant impact as voice becomes the world's default interface. The company's recent success in scaling revenue and securing major funding demonstrates the massive potential for growth and innovation in this space.
