About the role
- Insurance runs on phone calls - businesses call brokers, brokers call underwriters, millions of calls a day, most of them repetitive, most of them spent on hold.
- Voice is where trust gets built and where deals get closed, which also makes it the hardest part of the business to turn into compute.
- Voice isn't a feature here; it's a core system powering sales, operations, and service.
Responsibilities
- Build outbound at scale. Lead-qualification agents calling thousands of prospects a day.
- Build the platform. Move to custom infrastructure
- Design for compounding. Every conversation becomes structured decision traces the rest of the system learns from.
- 3-6 years building software, with production voice AI behind you at real volume (not demos).
- Build outbound at scale.
- Voice is the highest-leverage and hardest problem in our stack, which means you own a core system end-to-end and the bar is real - sub-700ms or it doesn't ship.
Requirements
- You know both fast deployment (VAPI, Retell) and custom infrastructure (Pipecat, LiveKit), and you understand telephony (SIP, RTP, WebRTC).
- Deep knowledge of real-time systems and latency optimization.
Nice to have
- telephony background (SIP/RTP)
- hands-on with specific platforms (VAPI, Retell, Pipecat, LiveKit)
- prior startup experience.
- The people who want this want exactly that pressure and ownership.
Compensation
- $170,000-$275,000 base + performance bonus + equity.
Benefits
- Uber commuter benefits; breakfast, lunch, and dinner provided; snacks and coffee stocked; free gym membership; health, dental, and vision.
- Bonus: telephony background (SIP/RTP)
