Software Engineer - Database Engineering

Snowflake empowers thousands of organizations to unlock the value of their data with high scale, concurrency, and performance. Snowflake platform powers and provides access to the AI Data Cloud, creating a solution for applications, collaboration, cybersecurity, data engineering, data lake, data science, data warehousing, and unistore. Our vision is a world with unlimited access to governed data, so every organization can tackle the challenges and opportunities of today and reveal the possibilities of tomorrow.

We’re hiring talented Software Engineers to join the Snowflake Database Engineering group and help build the world’s leading AI Data Cloud platform! Our group spans across three key areas -

1. Database Query Processing: This is the core data processing engine, powering the world's best data platform. This includes building SQL language features and developing novel query optimization and execution techniques for industry-leading performance. We also build features that automatically optimize workloads for performance and cost-efficiency.
2. Foundation Database: It is our large-scale distributed transactional KV store - internally called FDB - which powers all of Snowflake’s products and services and is rapidly evolving to meet Snowflake’s future needs. FDB houses Snowflake's metadata, allowing the service to be elastic, making the AI Data Cloud possible. FDB is also used to store user data for Unistore (and provides transactional and analytical optimized access paths).
3. Unistore: Unistore unites analytics with transactional data processing by removing OLAP data silos and providing real-time data produced by our customers' OLTP-based transactional systems. Unistore can tell you NOW using the superpower of HTAP (Hybrid Transaction and Analytics Processing) provided by Snowflake’s Hybrid Tables.
