Set the technical bar through architecture decisions, design reviews, and mentoring
You Have:At least 2+ years9 experience in software/ML engineering - which includes at least 1 years9 experience building LLM systems in production
Expert Python, hands on with LLM APIs and cloud platforms (AWS, Snowflake, Vertex)
Deep experience orchestrating multistep LLM workflows as execution graphs (e.g. LangChain/LangGraph).

Strong prompt engineering: tuning, versioning, and evaluation of prompts and model configs
A proven track record in AI evaluation, observability, and retrieval over enterprise data
Ability to explain complex AI concepts and tradeoffs clearly to nontechnical stakeholders
Fluency with agentic coding tools (e.g. Claude Code) and their architecture patterns (a strong plus)
