YC S11 · team ?
Jose is an exceptional founding engineer match with proven 0→1 product experience, full-stack expertise across frontend/backend, and direct experience building real-time omni-channel messaging systems (voice, SMS, WhatsApp, web) at scale. His background shipping production systems where reliability matters (99.9% message delivery, serving millions of users) and owning architecture/infrastructure decisions aligns perfectly with OneSignal's need for a founding engineer on a messaging platform. The main gap is no explicit demonstrated experience with push notifications or the specific notification platform patterns that OneSignal specializes in.
Hook: You've built omni-channel messaging infrastructure from scratch at Addie serving 10+ countries—OneSignal is looking for a founding engineer to scale their core personalized messaging platform.
Missing: Push notification systems, Mobile notification platform experience, APNs/FCM integration, Marketing automation platforms
