Job description

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.

Who You Are:

• You have 4+ years in a technical customer‑facing role, such as pre‑sales engineering, solutions architecture, customer engineering, or similar.

• You can write code well enough to build a working integration, read an API response, and debug issues without immediately pulling in an engineer.

• You have experience with voice, telephony, or contact center infrastructure, such as SIP, Twilio, Genesys, Five9, or similar systems.

• You’re comfortable speaking with both engineers and executives, and you adjust the level of detail without dumbing things down.

• You’re energized by technical sales: discovery, architecture, POCs, objection handling, and helping customers get live.

How We Work:

• Build something worthy of love - Craft matters. We aim to build products and experiences customers genuinely love, not just tolerate.

• Commit and follow through - We finish what we start and build trust by being people others can count on.

• Why not today? - We value urgency and momentum. The fastest path to customer value usually wins.

• Seek raw input - We go directly to customers, data, and teammates instead of relying on summaries or assumptions.

• It’s our problem - We operate as one team. We share credit, own mistakes together, and support each other when things get hard.

• Be direct and kind - We give feedback clearly, respectfully, and without delay.

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: YC, KP seed, Bessemer Series A

What We Offer:

• Real stake: We offer a 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
