Staff/Principal AI Software Engineer (Snowflake CoWork)

• The Cortex CoWork team is defining the future of AI for enterprise data. Our mission is to transform how the world’s largest enterprises interact with their data through flagship products like Snowflake (CoWork) Intelligence

• As a Principal AI Engineer, you will be a technical North Star for our AI initiatives. You won’t just execute on a roadmap; you will help define it

• You will tackle the most complex, “frontier” problems in agentic reasoning, NL-to-SQL, and enterprise-scale RAG, ensuring our AI products are not only innovative but fundamentally reliable and scalable for the Fortune 500

• Technical Strategy & Architecture: Define the long-term technical vision for Snowflake Intelligence. Lead the architectural design of multi-agent systems, complex tool-use frameworks, and self-correcting NL-to-SQL engines

• Drive Industry-Leading Reliability: Move beyond simple evals to build world-class, automated “hill-climbing” infrastructure. You will establish the methodology for how Snowflake measures and guarantees LLM performance across diverse customer schemas

• Cross-Functional Influence: Partner with Product and Engineering leadership to align AI capabilities with business goals. You will bridge the gap between Research (modeling) and Production (infra), ensuring the latest LLM breakthroughs are viable at Snowflake scale

• Ecosystem Thinking: Design extensible “context engineering” patterns—including advanced function calling and semantic layer integration—that can be leveraged by other Snowflake teams and external developers

• Technical Leadership & Mentorship: Act as a force multiplier. You will mentor Staff and Senior engineers, lead cross-functional “strike teams” on high-stakes projects, and foster a culture of technical excellence and rapid experimentation
