Our Enterprise ARR has grown 10x — customers like Amazon Ring, NY Life and Intuit deploy in weeks and expand rapidly when we support them well. Customer deployments now consume most of our current FDE capacity, which means platform roadmap work competes directly with delivery. We're opening more seats this quarter in San Francisco and New York to take on that unowned roadmap work. Steady-state accounts are handing off to our Agent Engineering team so FDEs can return to building the platform, not just running it.
Unlike a solutions engineer, an FDE ships code: into customer repos, into Vapi's GitOps configs, and into the Vapi platform itself.
This isn't CRUD engineering. You're building real-time, latency-sensitive systems that orchestrate multiple providers — speech-to-text, LLMs, text-to-speech, telephony — simultaneously, in production, at enterprise scale. It's the kind of systems problem most engineers only get to touch on infra teams at much larger companies, and you'll own it end to end.

Vapi lets enterprises deploy human-like voice agents in minutes. Whether you’re building a voice product or trying to handle millions of calls, Vapi’s reliable infrastructure and flexible APIs make it easy.
Everyone from YC startups to Fortune 500 companies rely on Vapi because it is:
Flexible: Plug in your APIs, your customer data, your models
Scalable: Handle millions of calls with <500ms latency
Secure: LLM guardrails, HIPAA, SOC-2
Helping enterprises over this challenge, Vapi, has raised $20 million in Series A funding, led by Bessemer Venture Partners with participation from Abstract Ventures, AI Grant, Y Combinator, Saga Ventures, and Michael Ovitz.
