Software Engineering Intern – Data Ingestion & Platform Infrastructure (Warsaw, Summer 2027)

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 Snowflake Snowflake delivers the AI Data Cloud, a global network where thousands of organizations mobilize data with near-unlimited scale, concurrency and performance. Our Warsaw engineering hub is one of Snowflake's key global R&D centers. Its teams build core systems that move, store and serve data for customers around the world. About the Teams You'll join one of two Warsaw teams working at the heart of Snowflake's platform: Data Ingestion: builds the high-throughput, low-latency pipelines that bring customer data into Snowflake at massive scale. The scope covers batch and continuous loading (Snowpipe, Snowpipe Streaming) and integrations with the wider data ecosystem, such as Kafka connectors. Platform Infrastructure Engineering (PIE): builds and runs the core infrastructure, reliability and performance tooling that keeps Snowflake's services fast, scalable and resilient for every workload. You'll work alongside experienced engineers who design distributed systems that run at very large scale, every day. What You'll Do Design, build and test features for production systems in data ingestion or platform infrastructure Write clean, well-tested, production-quality code in Java, C++, Go, Rust or Python Profile, benchmark and optimize systems where throughput, latency
