Responsibilities
- Overhaul how Close syncs email and calendars. Our sync engine has run for a decade; we're making a serious, ground-up investment in its performance and reliability. Millions of sales emails and calendar events, and when it breaks, customers feel it within ten minutes. You'd be in the middle of one of the biggest infrastructure rebuilds at Close.
- Take voice agents further into the call. We own the live conversation layer for Chloe's calls, and there's a lot of work ahead expanding our voice agent capabilities and infrastructure — including custom models tuned for conversational edge cases like voicemail and automated phone-tree detection (turns out "wait for the beep" is a hard AI problem).
- Solve inbound. So far Chloe makes calls; next she answers them. An inbound conversation can go anywhere — which raises real questions about specialized agents, a receptionist layer, and seamless call routing between them. Largely unexplored territory.
- Build native scheduling. Core calendar scheduling capabilities inside Close, plus more powerful scheduling for our agents. Various projects landing over the next 6–12 months.
- Design human orchestration of an agentic workforce. Agents create work for humans too — things to review, approve, respond to. How do we surface what's happening inside the CRM so each person engages with what actually needs them? A genuinely open product-engineering problem.
- Push connect rates and answer rates. Phone number pooling, local presence, branded calling, reputation monitoring. Real revenue impact, real telephony plumbing.
- Move our streaming and event substrate forward. Kafka, Redis, pub/sub. The plumbing the rest of the product runs on.
