Description
Consumer AI Mobile Product · iOS & Android · Full-Time or Contract Early-stage, stealth. Product details shared under NDA. The Role We're building a consumer AI product with a real-time, photorealistic AI persona: live voice conversation, persistent memory across sessions, camera-based perception, and a purpose-built harness around a frontier LLM — all orchestrated so the user experiences one continuous, seamless presence. This is not a chatbot wrapper and not a standard mobile build with AI features bolted on. It is an AI systems build with a mobile front end. The hardest work is in the real-time orchestration layer: managing multiple streaming AI vendors, hard latency budgets, cost-aware routing, and invisible transitions between them. You will be the lead engineer. What You'll Own • Real-Time Orchestration Layer: A backend router and state machine that determines, in real time, which technology is active, and switches between them invisibly. This is the architectural core. • Session Lifecycle Management: Starting, stopping, and resuming live streaming sessions on demand, under strict latency and cost constraints. • Real-time Voice Pipeline: Wake-phrase, hands-free, sub-1.5-second end-to-end response in noisy ambient conditions, with real turn-taking and interruption handling. • LLM Harness: Middleware enforcing persona consistency, structured memory injection, safety guardrails, and server-side deterministic rules. Not prompt engineering; a production system. • Persistent
