Principal Member of Technical Staff - Machine Learning Engineer

Redwood City, CA

 

The Applied AI organization mission is to design and AI solutions for data that are simple for all personas, including users, analysts, DBAs and developers and useful for all apps and all workloads. We are in aggressive growth journey with a team of highly energetic, technology savvy engineers and are looking to grow further to meet the demands of building a powerful AI data platform. You should be comfortable working in a fast-paced environment which requires agility, ability to adapt as priorities shift, and a passion to deliver high quality solutions. You will be part of a team of smart, motivated, diverse people.

 

The candidate will work on the Adaptive Bug Search (ABS) project. Adaptive Bug Search (ABS) is a service that uses machine learning technologies to identify duplicate and similar bugs. ABS uses deep learning techniques to improve the accuracy of the ABS bug predictions. The Adaptive Bug Search (ABS) team at Oracle is looking for motivated and talented individuals. Our team is an integral part of the software engineering process at Oracle in identifying potential duplicate bugs. ABS is also integrated in improving diagnostics of the Autonomous Database.

 

The candidate will also work on the Database Search and Assistant (DBSA).  DBSA accurately answers questions about the Oracle Database and related products and services. It improves productivity for developers, support, customers, and partners. DBSA consolidates the content from 

various data silos, divides this content into chunks, stores embeddings for these chunks in the Oracle Database, and uses the AI Vector Search capabilities in Oracle Database 23ai to find similar content chunks when generating answers using the OCI Generative AI Service.
