AI Full Stack Engineer

We’ve built an AI-native internal platform that powers every aspect of our Amazon brand management business. AI isn’t a feature — it’s the backbone.

  • LLMs classify and respond to inbound communications
  • AI generates pre-call intelligence briefs from raw enrichment data
  • A RAG system feeds context into every generation pipeline
  • An AI checkpoint system audits all generated content against quality gates

The platform is already live and scaling fast:

  • 17+ background services
  • 130+ frontend pages
  • 214 backend services
  • 184 database tables
  • Dozens of autonomous AI pipelines

We’re hiring an engineer who operates at the intersection of AI and production systems. You’ll build, optimize, and scale AI-powered infrastructure across the full stack.
