Vapi (/Vpi/):
Voice AI that resolves, not transfers
Powering 1 billion calls for companies like Amazon Ring, Intuit, ServiceTitan, and New York Life
Trusted by 1 million developers building the future of voice agents
Backed by Peak XV, Bessemer, Kleiner Perkins, M12, Y Combinator, and more with $72M raised
Why We’re Hiring This Role:
1M+ developers and 2.7M+ agents are built on our product surface.
Every assistant lives in our dashboard: Composer, Simulations, Monitoring, Knowledge Base, Versioning, Deployments. Non-deterministic systems, real-time call observability, eval loops, and a builder UX that has to feel like magic.
We're shipping the loops that take an agent from "demo" to "live in production for the Fortune 500."
What You’ll Do:
First 30 Days:
Make real calls. Build real assistants on Vapi across our main provider integrations (LLMs, STT, TTS, telephony). Get a working mental model of the platform end to end.
Ship your first product feature into customer hands.
By 60 Days:
Own a product area outright within the agent self-improvement loop or the trust and guardrails platform.
Drive a feature from spec to ship with PM and design, including the eval and rollout loops.
Use AI coding agents (Claude Code, Cursor, or similar) as a serious lever on your throughput.
By 90 Days:
Operate as a full peer to engineers on the team, owning your area without handholding.
Run the agent improvement loop end to end in your domain: authoring, evaluation, deployment, observation, iteration.
Be a core voice in product decisions, with multiple shipped features on your watch.
Who You Are:
Must-Haves
5+ years building product, with 2+ at an early-stage company.
Strong full-stack engineer, fluent in TypeScript, React, and a Node-based backend.
Track record shipping beautiful product surfaces that customers love and competitors copy.
Product instinct. You read a half-formed problem and figure out the right shape before someone hands you a spec.
Daily use of AI coding agents (Claude Code, Cursor, or similar) with opinions about where they help and where they don't.
Self-directed. You read the PR, open the product, and start building without waiting on permission.
Customer empathy and a bias for action: you ship, you own outcomes, and you care what users actually experience.
Nice-to-Haves
Background in voice AI, conversational AI, LLM applications, or telephony.
Worked on a developer-facing product (APIs, SDKs, dashboards) where the audience is technical.
You've built your own startup, or shipped a side project people actually use.
Open-source contributions or public writing on engineering, design, or product practice.
Why Vapi:
Generational impact: Build the human interface for every business.
Ownership culture: 70% of the company are previous founders.
Kind team: The founders, Jordan and Nikhil, are Canadians.
Tier-1 Investors: Peak XV (Series B), Kleiner Perkins, M12, Bessemer, YC.
What We Offer:
Real stake: Competitive salary and excellent equity ownership.
Comprehensive health coverage: medical, dental, and vision plans.
Team love: We love hanging out, and we do quarterly off-sites.
Flexible time off: take what you need.
More: catered meals, transportation, gym, and a $10k annual L&D budget.
