Job Summary
AI Engineer Mid/ Senior
Build the GenAI powered product experiences and the shared AI platform infrastructure that powers them. This includes RAG pipelines over the iHerb catalog and customer reviews, LLM driven personalization, a conversational Wellness Agent, agentic workflow systems, and the evals and MLOps layer that makes AI features production grade and repeatable. Specializations within this track include: RAG and personalization, agent frork and tool use, evals and guardrails, and LLM application development for internal business functions such as marketing automation and BI agents.
What you will do:
- Design, build, and operate production AI features: RAG pipelines, LLM driven recommendations, conversational agents, or agentic workflow automation.
- Build the shared AI platform layer: retrieval infrastructure, eval frameworks, model monitoring, guardrails, and observability.
- Write LLM applications and integrations with marketing platforms, BI tools, or customer facing product surfaces.
- Evaluate model and feature quality using structured eval frameworks; iterate on prompts, retrieval strategies, and model selection using data.
- Use AI driven SDLC tooling such as Claude Code as a daily practice for both AI and non AI code.
- Coordinate with the Personalization team to align GenAI product features with existing ML personalization signals.
- Document AI system design decisions, evaluation results, and operational lessons in the shared knowledge base.
Track specific required skills:
- Python proficiency; comfortable building and operating production LLM applications.
- Hands on experience with at least one specialization: RAG and retrieval systems, LLM evaluation, agentic frameworks (LangChain, LlamaIndex, or similar), or LLM based workflow automation.
- Understanding of prompt engineering, context window management, and LLM output quality tradeoffs.
- Familiarity with vector databases, embedding models, or semantic search.
- Experience with e commerce platforms, product catalogs, or high traffic consumer applications.
- Exposure to MLOps tooling or model deployment pipelines.
- Experience working in distributed teams across the US, China, and Latin America.
