Close ist ein benutzerfreundliches CRM, das speziell für kleine Unternehmen und Startups entwickelt wurde und den Schwerpunkt auf Geschwindigkeit und Effizienz in Verkaufsprozessen legt. Es optimiert die Kommunikation, Automatisierung und Integrationen, um die Produktivität von Verkaufsteams zu steigern. Mit Funktionen wie Verkaufsautomatisierungstools, Kommunikationsmöglichkeiten per Anruf und E-Mail sowie Aufgabenmanagement auf einer Plattform zielt Close darauf ab, den Verkaufsprozess zu vereinfachen, sodass sich Teams auf den Abschluss von Geschäften konzentrieren können, ohne den Ballast traditioneller CRMs.

Beschreibung

• 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. • 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. • 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. • Build native scheduling. Core calendar scheduling capabilities inside Close, plus more powerful scheduling for our agents. • Design human orchestration of an agentic workforce. Agents create work for humans too — things to review, approve, respond to. • Push connect rates and answer rates. Phone number pooling, local presence, branded calling, reputation monitoring. • Move our streaming and event substrate forward. Kafka, Redis, pub/sub.

🎯 Anforderungen

• A seasoned engineer. Python is our backbone, but perhaps you've worked across Go, Rust, or TypeScript. You pick the right tool for the workload rather than retreating to what you know. • Deeply experienced with email and calendar platforms. IMAP, sync protocols, calendar APIs, and the thousand edge cases of oddly configured enterprise mail servers. This is the experience that makes someone successful on this team fastest. • Fluent in real-time and async distributed systems. WebRTC, WebSockets, queues, streaming. You've debugged a production incident where latency budgets didn't hold. • Opinionated about AI in real-time workflows. You've built or used live transcription, voice agents, or in-the-loop AI features. You have a view on what's ready for production versus what's still a demo. • At home in the gnarly bits. Telephony providers, codecs, retries, eventual consistency. You're drawn to the systems where edge cases actually matter. Deep Twilio or similar telephony experience is a big plus (not a requirement — but a game changer off the bat). • Working with AI in your day-to-day. You use AI tools in your own workflow to ship faster, write tighter code, and reason about unfamiliar parts of the codebase. • A builder first. You'd rather get a sloppy v1 in front of fifty customers than spend three weeks on abstractions. You ship.
