YC S11 · team ?
Jose is an exceptional full-stack engineer with proven experience building AI products at scale, including real-time voice systems and LLM agents—directly relevant to OneSignal's omni-channel personalization needs. His founding engineer background at Addie demonstrates ability to ship production AI features across multiple channels (voice, SMS, WhatsApp), and his technical depth across Python, TypeScript, FastAPI, and LangGraph aligns well with the role. However, the job posting is incomplete and lacks specific technical requirements, making precise alignment difficult, and his experience skews toward AI/ML engineering rather than traditional full-stack product development.
Hook: Your founding engineer who shipped real-time AI voice and LLM agents across web, SMS, voice, and WhatsApp to 10+ countries would bring hands-on experience scaling personalized omni-channel systems to OneSignal.
Missing: OneSignal platform specifics, Mobile push notification expertise, Customer segmentation at scale, A/B testing and analytics infrastructure
