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.
