Full Job Description
📋 Description
- • Serve as the primary technical expert during enterprise sales cycles, leading technical discovery, demonstrations, and proof-of-concept (POC) development for Vapi’s voice AI platform.
- • Partner directly with Account Executives to align technical solutions with customer business goals, including IVR replacement, outbound dialing, agent-assisted support, and appointment scheduling workflows.
- • Build and deliver custom, production-grade demos that showcase Vapi’s ability to integrate with existing telephony systems such as Twilio, Genesys, or Five9, and orchestrate LLM-based voice agents in real-world environments.
- • Translate complex technical architecture — including SIP, voice APIs, and contact center integrations — into clear, compelling narratives for both engineering teams and executive stakeholders.
- • Own the end-to-end technical process for enterprise deals, from initial technical call through deployment and go-live, ensuring seamless customer onboarding and adoption.
- • Create reusable technical artifacts, documentation, and playbooks for internal teams, including integration patterns, objection-handling guides, and deployment checklists.
- • Act as a bridge between customers and product/engineering teams by identifying and escalating recurring technical pain points, feature gaps, and integration challenges.
- • Maintain deep fluency in Vapi’s product capabilities, customer use cases, and competitive landscape to provide accurate, honest, and confident responses to technical objections.
- • Shadow enterprise sales calls and customer onboarding sessions to rapidly build domain expertise in telephony infrastructure, voice AI workflows, and enterprise procurement processes.
- • Collaborate with customer success and support teams to ensure smooth handoff post-sale and to gather feedback for product improvement.
- • Contribute to the evolution of Vapi’s enterprise sales motion by refining demo frameworks, POC templates, and technical qualification criteria based on real-world customer interactions.
- • Represent Vapi at industry events, customer workshops, and technical forums to build credibility and thought leadership in the voice AI and contact center automation space.
- • Maintain a high standard of craftsmanship in all technical deliverables, ensuring demos and integrations are robust, scalable, and reflect Vapi’s commitment to building products customers love.
- • Operate with urgency and ownership, prioritizing the fastest path to customer value while maintaining technical integrity and transparency.
- • Embody Vapi’s cultural principles: be direct and kind, seek raw input, commit and follow through, and treat every challenge as a shared problem to solve.
🎯 Requirements
- • 4+ years in a technical customer-facing role such as pre-sales engineering, solutions architecture, or customer engineering.
- • Proven ability to write code to build working integrations, read API responses, and debug technical issues without immediate engineering support.
- • Hands-on experience with voice, telephony, or contact center infrastructure (e.g., SIP, Twilio, Genesys, Five9).
- • Comfort speaking with both technical engineers and C-level executives, adjusting communication depth without oversimplifying.
- • Strong motivation for technical sales: discovery, architecture design, POC development, and objection handling.
- • Demonstrated ability to document technical processes and create reusable assets for internal teams.
🏖️ Benefits
- • Competitive salary and excellent equity ownership.
- • Comprehensive health coverage including medical, dental, and vision plans.
- • Flexible time off — take what you need.
- • $10,000 annual learning and development budget.
- • Catered meals, transportation assistance, and gym membership.
