Data ingestion, storage, and access

Model training, deployment, and orchestration

Define how multiple model types interact in a single system (statistical, ML, causal)

Automation and decision-support

Intelligence and human authority

Anticipate scaling, safety, and failure modes of AI-enabled systems

Who You Are

Senior architect or engineer with experience building AI-enabled platforms

Deep understanding of distributed systems and AI infrastructure
