Try talking to Vapi now!

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.

A track record operating at senior or staff scope: independently owning customer-facing backend product areas from an ambiguous problem through measurable production outcomes.

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.

Experience building distributed or asynchronous systems with databases, queues, workflows, or event-driven patterns—and reasoning clearly about failure modes.

Strong product judgment: you start with the user problem, turn incomplete requirements into a clear technical approach, and make tradeoffs based on customer impact.

Production ownership: you care about testing, observability, reliability, incident response, safe rollouts, and what happens after launch.

Regular, thoughtful use of AI-assisted development tools to improve speed and quality, paired with strong engineering judgment about the result.

Self-direction, customer empathy, and clear communication. You stay hands-on, collaborate directly across functions, and remain accountable for outcomes.

Experience with Postgres and high-volume, event-driven systems using queues or durable workflows such as BullMQ, Kafka, or Temporal.

Experience with real-time systems, voice or telephony, LLM-powered products, or AI agents.

Experience operating cloud-native services on AWS and Kubernetes/EKS.

Experience building developer platforms, public APIs, SDKs, or dashboards used by technical customers.

Experience at a fast-growing startup, building a zero-to-one product, or founding a company.

Open-source contributions, public technical writing, or other evidence of craft beyond your day job.

Craft matters. We aim to build products and experiences customers genuinely love, not just tolerate.

We finish what we start and build trust by being people others can count on.

We value urgency and momentum. The fastest path to customer value usually wins.

We go directly to customers, data, and teammates instead of relying on summaries or assumptions.

We operate as one team. We share credit, own mistakes together, and support each other when things get hard.

We give feedback clearly, respectfully, and without delay.
