Principal Member of Technical Staff-Bay Area

Description

Design develop troubleshoot and debug software programs for databases and cloud services with emphasis on new extensions to SQL. Implement data structures and algorithms to accelerate query performance. Work on Machine Learning algorithms that improve automation of query processing like automated result cache automated partitioning automated clustering and zonemaps.

As a member of the software engineering division you will take an active role in the definition design implementation and evangelization of new database execution features. You will also be analyzing the performance and scalability of the features and improve them. Work is complex and research-centric involving application of advanced technical and problem-solving skills in area efficient execution of sql queries. As a leading individual contributor you will be providing direction and mentorship as well.

Many of our algorithms have been patented and our work has been published in major conferences. We are responsible for providing scalability of sql operators for parallel queries and for memory usage. A most recent area of interest is vectorized and columnar processing. We extended the SQL language to identify data that is closest match to query vector. We generate optimal query plans for retrieve data fast. We take advantage of new on-disk and in-memory storage formats and hardware caching characteristics to improve jo
