Agent Engineer

Voice AI that resolves, not transfers. Most phone systems trap callers in menus and scripts. Vapi is the platform for deploying voice agents that know your business and can listen, adapt, and resolve in minutes.

The numbers: 1 billion calls. 1 million developers. 10x enterprise ARR growth The customers: Amazon Ring, ServiceTitan, New York Life, Intuit, Kavak, and thousands more, from YC startups to the Fortune 500 The news: a $50M Series B led by Peak XV Partners, with Bessemer Venture Partners, Kleiner Perkins, M12 (Microsoft's Venture Fund), Y Combinator, and our earlier backers.

Total raised: $72M Why We’re Hiring This Role: Vapi is moving deeper into enterprise customers, where buyers are technical and evaluations depend on clear architecture, credible demos, and working POCs. Customers want to understand how Vapi fits into real production workflows like IVR replacement, outbound dialing, agent-assisted support, appointment scheduling etc.

This is one of our first Solutions Architect hires, with real scope to shape how we sell, demo, document, and bring enterprise customers live. What You’ll Do: 30 Day : Learn Vapi’s product, customer use cases, sales motion, and common technical objections.

Shadow enterprise calls, understand our voice-agent architecture, and start building fluency across telephony, LLM orchestration, integrations, and contact center workflows. 60 Day : Own technical discovery and demos for active enterprise deals.

Partner closely with AEs on account strategy, build customer-specific demos, help design POCs, and answer technical questions clearly and honestly. 90 Day : Lead the technical side of enterprise deals from first call through close and go-live. Create reusable artifacts for the team, document integration patterns and common objections, and feed repeated product gaps back to engineering and product.
