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

- An AI checkpoint system audits all generated content against quality gates

The platform is already live and scaling fast:

- 130+ frontend pages
- 214 backend services
- 184 database tables
- Dozens of autonomous AI pipelines
