- Has built and deployed production AI systems, including RAG and vector search
- Knows prompt engineering, AI safety, and content filtering best practices
- Ideally has expert-level Rails experience (3+ years), including REST APIs, PostgreSQL, ActiveRecord, and RSpec
- Can lead AI integration in full-stack environments and collaborate across teams
- Understands LangChain, LlamaIndex, or similar frameworks (or can ramp fast)
- Communicates clearly, moves fast, and thrives in ambiguity
Bonus if you’ve:
- Built agent-based AI features inside Rails apps
- Led AI-powered UI/UX design or AI feature launches
