What the role asks for

What you'd do

  • 30 Days: Make real calls and build real assistants across LLM, speech-to-text, text-to-speech, and telephony integrations. Develop a working mental model of how Vapi’s product surfaces map to APIs, services, data systems, and production workflows, then ship your first scoped backend product improvement.
  • 60 Days: Own a meaningful backend area in agent self-improvement, trust, or guardrails. Take a customer problem from product spec to shipped system-designing the API, services, and data model; defining evaluation and rollout criteria; and instrumenting the result. Use AI coding agents thoughtfully as a throughput and quality lever.
  • 90 Days: Operate as an independent owner for a customer-facing backend area. Run the full improvement loop-authoring, evaluation, deployment, observation, and iteration-while improving reliability and developer experience. Be a core voice in product decisions and have multiple meaningful improvements in production.

What they're asking for

  • A track record operating at senior or staff scope: independently owning customer-facing backend product areas from an ambiguous problem through measurable production outcomes.Skill
  • Strong hands-on experience with TypeScript/Node.js, Go, or a comparable backend stack, plus the ability to design clear APIs, services, and data models.Skill
  • Experience building distributed or asynchronous systems with databases, queues, workflows, or event-driven patterns-and reasoning clearly about failure modes.Skill
  • Strong product judgment: you start with the user problem, turn incomplete requirements into a clear technical approach, and make tradeoffs based on customer impact.Skill
  • Production ownership: you care about testing, observability, reliability, incident response, safe rollouts, and what happens after launch.Skill
  • Regular, thoughtful use of AI-assisted development tools to improve speed and quality, paired with strong engineering judgment about the result.Skill
  • Self-direction, customer empathy, and clear communication. You stay hands-on, collaborate directly across functions, and remain accountable for outcomes.Skill

Job description

Vapi (/ˈVɑːpi/): - 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 - Try talking to Vapi now! https://vapi.ai/ WHY WE’RE HIRING THIS ROLE: - More than 1 million developers have built 2.7M+ agents on Vapi. Every assistant depends on a growing product surface-from Composer, Simulations, Monitoring, and Knowledge Base to Versioning and Deployments. - Behind those experiences are hard backend product problems: durable APIs and data models, real-time and asynchronous workflows, observability, evaluations, guardrails, and reliable operation of non-deterministic systems. - We’re hiring a backend product engineer to own those systems end to end and help customers move voice agents from a compelling demo to dependable production-at Fortune 500 scale. The work is genuinely hard and unusually fun. What You’ll Do: - 30 Days: Make real calls and build real assistants across LLM, speech-to-text, text-to-speech, and telephony integrations. Develop a working mental model of how Vapi’s product surfaces map to APIs, services, data systems, and production workflows, then ship your first scoped backend product improvement. - 60 Days: Own a meaningful backend area in agent self-improvement, trust, or guardrails. Take a customer problem from product spec to shipped system-designing the API, services, and data model; defining evaluation and rollout criteria; and instrumenting the result. Use AI coding agents thoughtfully as a throughput and quality lever. - 90 Days: Operate as an independent owner for a customer-facing backend area.

You stay hands-on, collaborate directly across functions, and remain accountable for outcomes.
