　　The group focuses on improving Scalability, High availability, Reliability and performance of Oracle Database Server products by Designing, developing and carrying out stress, integration, system and performance tests, which simulate complex real world scenarios on Very Large DBs (VLDB). The team discovers critical product defects and works closely with development groups to resolve them resulting in the highest quality of products before they get released to customers (Cloud and On-Premise) .

　　With over 200 dedicated Product Engineers distributed across the globe and working on a single mission, our group has been instrumental in delivering highest quality Oracle Server products during every major release cycle.

　　Job Description

　　SHARP-VLDB / System Test Development group envisions & architects Large-scale, High load/volume, Massively concurrent multi-tier simulation tools & Data-Centric applications to emulate real world Enterprise DB usage scenarios to detect product defects & architectural limitations. Multi-tier Stress/Integration/System/Performance Test simulations are conducted in lab environment (grid of hundreds of servers) mimicking end-to-end high stress scenarios. This simulation effort involves DB Design (TB of data, Billions of rows, 1000s of tables), massively concurrent workload/query development (millions of transactions per sec, 1000s of queries per hour), concurrency levels (5000-10000 parallel users) and boundary/destructive testing. The focus is primarily on high-end enterprise customer use-case scenarios (Ex: Yahoo, Amazon, Apple, LinkedIn, Dell etc.) involving very large & dimensions of testing.

　　As a member of this group, you will Learn and Shape the Next-Gen Oracle DB features as they are designed (19c/20c and beyond) and gain experience in Tuning/Debugging VLDBs with thousands of concurrent users simulating real-world production/cloud systems.
