Member of Technical Staff, Backend

Why We’re Hiring

This role is part of a rapidly growing team building the future of voice AI. With 1M+ developers and 2.7M+ agents built on our platform, we're looking for someone who can own and drive product features.

What You’ll Do

• Make real calls and build real assistants on Vapi across main provider integrations.
• 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 by 90 days.
• 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.
• 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.

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.
• Built your own startup, or shipped a side project people actually use.
• Open-source contributions or public writing on engineering, design, or product practice.
