Founding Full-stack AI/ML Engineer

Founding Engineer (Full-Stack / Real-Time AI Systems)

Remote (exceptional only)
 

TwinTone is building AI Creators that live stream, sell products, and drive revenue 24/7.
 

We turn real creators into monetizable AI Twins powering:

• AI Live Shopping for brands
• Automated UGC distribution at scale
• AI-powered casino & iGaming live streams
   

We operate at the intersection of AI, real-time video, and commerce infrastructure.

• 2,000+ creators in our network
• 1.2B+ monthly distribution reach
• Growing SaaS + live-stream revenue
• US-based company, backed by angels.
   

We have a working AI streaming pipeline in production and a platform under active development. We need someone who can take ownership of the full technical stack and harden it for scale.
 

This is not a maintenance role — this is rebuild + scale + ownership.
 

What You'll Do

• Own architecture across the full stack — Python streaming backend, TypeScript platform, GPU infrastructure
• Harden the real-time AI streaming pipeline (chat → LLM → TTS → avatar → RTMP, currently ~4-8s end-to-end)
• Scale concurrent AI video sessions with low latency via LiveKit + WebRTC
• Build the creator onboarding portal and brand dashboards (greenfield Next.js)
• Improve reliability across the platform monorepo (Hono API, React frontend, Postgres/Drizzle)
• Optimize LLM + avatar rendering costs across GCP GPU instances and RunPod
• Design event-driven systems connecting AI responses, video pipelines, and content distribution
   

Build features across:

• AI live casino streams (iGaming use cases)
• AI live shopping streams
• Creator onboarding + IP licensing portal
• Brand & partner dashboards
• Content pipeline + distribution engine
• Analytics and billing
   

Work directly with the founder on roadmap and technical direction. Hire and lead the future engineering team.

You will own the technical foundation of the company.

AI Streaming (ARIA):

• Python 3.11+, asyncio/aiohttp
• Claude API (LLM brain + moderation)
• ElevenLabs (TTS)
• Wav2Lip / FasterLivePortrait (avatar lip-sync)
• YOLO + PaddleOCR (game state detection)
• FFmpeg → RTMP (stream compositing)
• LiveKit (real-time video sessions)
• GCP L4 GPU + RunPod (GPU compute)
   

Bonus If You've Worked With

• Real-time streaming (WebRTC / RTMP / HLS / LiveKit)
• GPU infrastructure management (GCP, RunPod, or similar)
• AI video/voice APIs (ElevenLabs, Tavus, lip-sync models)
• Event-driven Python async systems
• High-concurrency WebSocket systems
• Payments / marketplace architecture (Stripe, billing)
• iGaming / betting infrastructure & compliance
• Large-scale content distribution systems
• Drizzle ORM / Supabase at scale
   

Who You Are

• Backend-leaning full-stack engineer comfortable in both Python and TypeScript
• Strong systems thinker — you've debugged latency across distributed pipelines
• Builder > talker
• Comfortable in early-stage chaos
• Opinionated about clean architecture
• Care deeply about latency, performance, and scalability
• Want to build a category-defining company

This is not a 9-5 role — this is a founder-level role.
 

What You Get

• Meaningful founding equity
• Direct ownership of architecture
• Real customers + revenue
• Live AI product in market (streaming now)
• Opportunity to build infrastructure powering AI-driven commerce + gaming
