- Integrate frontend applications with AI backends (LLMs, agent orchestration layers, RAG pipelines)
- Translate complex AI behaviors into clear, usable user experiences

- Solid understanding of frontend–backend interaction patterns in AI systems (state, latency, retries)
- Ability to independently take AI-driven features from concept to production
- Strong communication skills and product ownership mindset
Strongly Preferred
- Experience working with AI agents , tool-calling flows, or multi-step LLM workflows
- Familiarity with RAG-based UI patterns (search, citations, context panels)
- Experience visualizing agent state, reasoning steps, or tool execution in the UI
- Built or shipped a production LLM chatbot or copilot
- Experience in AI-first or fast-iteration product environments
Nice to Have
