Senior Member of Technical Staff, Voice

The Problem36 million businesses in America need insurance—it’s not optional. 77% are underinsured. 40% have no coverage at all. The distribution system failed them: too slow, too opaque, too confusing.Voice is the lifeblood of insurance. Businesses call brokers. Brokers call underwriters. The industry runs on phone conversations—millions of calls per day, most of them repetitive, most of them waiting on hold.We’re adding ~1,000 customers per month. We’ve grown 100x since last year. We’re looking to do even more this year—and that’s why we’re hiring.Voice is how trust gets built. Voice is how deals get closed. Voice is where the industry lives.The ThesisVoice is the hardest part to make computational. Getting voice right is what separates AI demos from AI that operates. Companies like Giga (DoorDash) and HappyRobot (DHL, Ryder) are proving that voice AI can run core operations at enterprise scale. We’re building the same for insurance.The RoleYou’ll own our entire voice AI infrastructure—architecture, implementation, scaling, continuous improvement. Voice isn’t a feature at Harper. It’s a core system that powers sales, operations, and customer service.Today we have working voice agents. But we’re at 1% of where we need to be. We need to scale from hundreds of calls to thousands. From functional to exceptional.What You’ll DoBuild outbound at scale — Lead qualification agents calling thousands of prospects dailyCreate inbound customer service — 24/7 agents handling policy questions, certificate requests, claimsShip operations and underwriting voice — 20-30 minute insurance applications over the phoneBuild platform infrastructure — Move to custom infrastructure; sub-700ms latency; 10,000+ concurrent callsDesign systems that compound — Every conversation becomes structured decision tracesYou Might Be a Fit If…You’ve built production voice AI (not demos—significant production volume)You know both fast deployment (VAPI, Retell) and custom infrastructure (Pipecat, LiveKit)You understand telephony (SIP, RTP, WebRTC)You’ve achieved sub-second latency in productionYou write code with AI (Cursor, Claude Code)You’re 3-6 years into your careerRequirements3-6 years software engineering experienceProduction voice AI experience at scaleDeep knowledge of voice infrastructure and real-time systemsExperience with latency optimizationBased in San Francisco or willing to relocateNice to HaveTelephony background (SIP/RTP)Experience with specific platforms (VAPI, Retell, Pipecat, LiveKit)Prior startup experienceCompensationSalary: $170,000–$275,000 + performance bonuses & equityLocation: San Francisco, in-officeBenefitsHealth, dental, and vision insuranceCommuter benefitsTeam meals and snacksThe Process15-min founder call — Alignment on mission and paceIf in SF: Super Day on-siteIf outside SF: Technical phone screen, then on-siteTo ApplyVoice is the highest-leverage problem in our stack.
