Principal /Staff AI Engineer - Cortex Code Agentic System

At Snowflake, we are powering the era of the agentic enterprise. To usher in this new era, we seek AI-native thinkers across every function who are energized by the opportunity to reinvent how they work. You don’t just use tools; you possess an innate curiosity, treating AI as a high-trust collaborator that is core to how you solve problems and accelerate your impact. We look for low-ego individuals who thrive in dynamic and fast-moving environments and move with an experimental mindset — who rapidly test emerging capabilities to discover simpler, more powerful ways to deliver results. At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done. ABOUT THE ROLE The Cortex Apps 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 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. WHAT YOU WILL DO IN THIS ROLE: * 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. REQUIREMENTS: * Experience: 10+ years of software engineering experience, with 3+ years specifically leading the deployment of LLM-based applications at massive scale. * Education: Bachelor’s, Master’s, or PhD in Computer Science, AI, or a related field. * Expertise: Deep, "under-the-hood" understanding of LLM orchestration. You should be an expert in prompt optimization, semantic modeling, and building robust guardrails for non-deterministic systems. * Systems Thinking: Proven track record of designing complex systems that integrate AI with traditional data stacks (SQL, Retrieval Systems, Semantic Layers). * Communication: Exceptional ability to communicate complex technical trade-offs to both executive leadership and ICs. You are as comfortable in a design doc as you are in a boardroom. * Proven Impact: You have previously held a "Principal" or equivalent high-level IC role, or have led the technical launch of a major AI product used by millions. ABOUT SNOWFLAKE Snowflake is the AI Data Cloud. We aren't just shipping "wrappers"; we are building the foundational intelligence layer for the world’s data. Join us as we scale Cortex, including Snowflake Intelligence, Cortex Agents, Analyst, and Search—to define the next decade of enterprise computing. Every Snowflake employee is expected to follow the company’s confidentiality and security standards for handling sensitive data. Snowflake employees must abide by the company’s data security plan as an essential part of their duties. It is every employee's duty to keep customer information secure and confidential. Snowflake is growing fast, and we’re scaling our team to help enable and accelerate our growth. We are looking for people who share our values, challenge ordinary thinking, and push the pace of innovation while building a future for themselves and Snowflake. How do you want to make your impact?

At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done. Snowflake's Data Engineering organization builds the platform that ingests, transforms, and stores data for modern lakehouse architectures — powering billions of queries, DML, and DDL operations with industry-leading price-performance. We lead the industry's shift to open data lakes through our work on Iceberg and Polaris, and we deliver capabilities like Snowpark, Dynamic Tables, cross-region replication, time travel, and zero-copy cloning at enterprise scale. We are investing in a new line of applied research — building toward verified data infrastructure and trustworthy data systems — that brings formal methods, automated reasoning, and modern AI techniques to bear on the hardest problems in our distributed systems and developer tooling. The goal is to improve correctness, reliability, and engineering velocity at a scale very few platforms operate at. We're hiring at both the Staff and Principal level; we'll calibrate the offer to the candidate's experience and scope of impact. WHAT YOU'LL DO * Lead research projects that apply formal methods, program analysis, automated reasoning, and AI-driven techniques (including code generation and modeling) to real problems in our cloud data platform. * Translate research ideas into prototypes, then into shipped capabilities that move concrete business metrics — quality, velocity, reliability, and operational performance at scale. * Partner closely with engineering leaders, product managers, and key customers to identify high-leverage opportunities and turn them into deliverables. * Influence the engineering and product roadmap; advise leaders on which research directions are pragmatic and which are not. * Train and uplevel engineering teams on new methods, and scale those methods across the organization. * Maintain expertise at the frontier of the field through publications, conference participation, open-source contributions, and patent filings. WHAT WE'RE LOOKING FOR * PhD (or equivalent research experience) in Computer Science or a closely related field. * Depth across the areas this role sits at the intersection of: * Formal methods — e.g., model checking, theorem proving, SAT/SMT, program verification, type systems, or program analysis. * Distributed systems — designing, reasoning about, or verifying large-scale concurrent and distributed systems. * Software engineering — strong fundamentals; able to go from a research idea to production-quality code in collaboration with engineering teams. * AI / ML — practical experience applying modern ML, including LLMs, to systems problems such as code generation, synthesis, or automated reasoning. * 8+ years applying theoretical computer science to large-scale software systems — ideally cloud data platforms, distributed systems, or developer infrastructure. * Demonstrated ability to drive company-level initiatives in partnership with engineering and product leadership. (Weighted more heavily for Principal-level candidates.) * Track record of technical contribution to the field — publications, open-source work, patents, or comparable evidence of impact. * Comfortable in a fast-paced, ambiguous environment where impact is measured by what ships.
