Senior Member of Technical Staff, Voice

What You'll Do

• Build outbound at scale. Lead-qualification agents calling thousands of prospects a day.
• Run inbound service. 24/7 agents handling policy questions, certificate requests, claims.
• Ship ops and underwriting voice. 20–30 minute insurance applications completed over the phone.
• Build the platform. Move to custom infrastructure; sub-700ms latency; 10,000+ concurrent calls.
• Design for compounding. Every conversation becomes structured decision traces the rest of the system learns from.

What We're Looking For

• 3–6 years building software, with production voice AI behind you at real volume (not demos).
• You know both fast deployment (VAPI, Retell) and custom infrastructure (Pipecat, LiveKit), and you understand telephony (SIP, RTP, WebRTC).
• You've hit sub-second latency in production and know how you got there. Deep knowledge of real-time systems and latency optimization.
• You write code with AI (Cursor, Claude Code).
• Bonus: telephony background (SIP/RTP); hands-on with specific platforms (VAPI, Retell, Pipecat, LiveKit); prior startup experience.

The Reality

• On-site in San Francisco, in person, long days, high standards.
• 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.
• The people who want this want exactly that pressure and ownership.

Logistics

• Compensation: $170,000–$275,000 base + performance bonus + equity.
• Location: San Francisco, in-office. Based here or willing to relocate.
• Benefits: Uber commuter benefits; breakfast, lunch, and dinner provided; snacks and coffee stocked; free gym membership; health, dental, and vision.
• Process: 15-min founder call → Super Day on-site (technical phone screen first if you're outside SF).
