Job details

Experience: 5+ years of software engineering experience with at least 3 years deeply focused on voice/audio systems
Posting language: English

Original job description

The Mission We're building an AI-powered insurance brokerage transforming the $900B commercial insurance market. Voice is our primary growth lever - the majority of insurance transactions happen over phone calls. We need an exceptional Head of Voice AI to architect voice systems that will power thousands of conversations daily across growth, sales, operations, and customer service. You'll use low-code platforms like VAPI or Retell for quick prototyping and rapid deployment of production voice agents, then progressively build custom infrastructure using LiveKit and Pipecat as we scale. Your systems will handle everything from cold outreach and lead qualification to complex multi-turn underwriting conversations and 24/7 customer support. We're committed to "Staying REAL" with our AI systems - building agents that are Reliable, Experience-focused, Accurate, and have Low latency. You'll work directly with the CEO and CTO with a bias toward action. We live by core principles: "There is no try, there is just do," "Actions lead to information, always default to action," and "Strong opinions lead to information." Outcomes You'll Drive Voice Infrastructure & Scale

Deploy production voice agents within weeks using VAPI or Retell for quick prototyping and immediate business impact
Transition to custom voice infrastructure with LiveKit and Pipecat as volume scales
Achieve sub-700ms latency across the entire voice pipeline while maintaining conversation quality
Scale to 10,000+ concurrent calls with appropriate architecture evolution and optimization

Create lead nurturing systems with personalized follow-ups that move prospects through the sales funnel
Implement predictive dialing and call pacing algorithms for maximum efficiency
Design qualification workflows that gather key information and route to appropriate human agents

Operations & Underwriting Support

Develop form-filling agents handling 20-30 minute insurance application conversations
Build underwriter follow-up systems that collect additional risk information through natural, multi-turn dialogue
Create document collection workflows guiding customers through providing licenses, photos, and business documentation
Implement intelligent escalation paths that know when to loop in human underwriters

Customer Service Excellence

Design 24/7 policy servicing agents that explain coverage, generate certificates, and process endorsements
Build claims intake systems that empathetically gather first notice of loss (FNOL) information
Create payment processing agents handling failed payments, billing updates, and payment plans
Develop proactive outreach systems for policy renewals, payment reminders, and important updates

Platform Development

Create no-code/low-code tools enabling non-technical teams to create and modify voice workflows
Build conversation analytics tracking quality metrics, completion rates, and customer satisfaction
Develop A/B testing frameworks for voice personas, prompts, and conversation strategies
Implement voice agent templates for common insurance workflows
Create comprehensive monitoring to track latency, accuracy, and conversation outcomes

Our Voice AI Philosophy

Start Practical, Scale Smart: Begin with low-code platforms for rapid deployment, build custom infrastructure as needed
Voice is the Channel: Recognize that voice is how insurance happens - optimize for natural conversation
Latency is Everything: Sub-700ms response times or we've failed
Revenue Impact First: Every voice interaction should drive conversion, retention, or efficiency
Context Preservation: Maintain full context even across 30+ minute calls
Fail Gracefully: Always have intelligent fallbacks and recovery mechanisms
Data-Driven Iteration: Measure everything, iterate based on real conversations
Ship Daily: Deploy quickly, learn fast, improve continuously
REAL Framework: Every interaction must be Reliable, Experience-focused, Accurate, and Low-latency

Join Us To Transform Insurance This is an early-stage role at a fast-moving startup where you'll define how voice AI transforms insurance. Voice is our biggest point of leverage - you'll directly impact how we scale 10x without proportional headcount increases. You'll start with practical solutions that work today, then build the infrastructure to scale tomorrow. You should have experience building voice AI systems that real customers use at scale - handling thousands of calls per day, maintaining sub-second latency, and gracefully handling all the edge cases that come with production voice systems. We value engineers who ship daily and measure success by business impact, not technical complexity. We require you to be in San Francisco and work from our office 5.5 days per week. We'll cover relocation costs and believe the best teams collaborate intensively in person.
