We are an engineering team specifically focused on the Performance, Scalability, and Reliability (PSR) aspects of the Oracle software. Our goal is to achieve highest levels of performance, scalability, reliability, high-availability and serviceability for mission critical Oracle Applications. Our focus is spread across all products (J2EE platform and Fusion Apps, CRM, and Business Intelligence). The teams in the above mentioned areas cover the following aspects: Product Development, PSR, HA, Sizing, Benchmarking, Monitoring and Manageability Tools and 3rd tier Customer escalations
P1 customer specific product optimizations, triage and drilldown customer pain points, key business flows analysis and bug filing/follow ups, attend and resolve show stopper escalations, environment sizing, scaling and capacity planning to support large/medium SaaS/On Demand/On Premise customer implementations that have specific scale-out and flow requirements. Environment Audits and fine tunings to support large scale deployments and scale in pre-go-live and post go live phases. Benchmarks covering key clicks from P1 flows to showcase RT’s and scalability. Work with key stake holders in establishing global customer success stories and make them referable. 3-8 yrs Industry experience + BS in Engineering or Science or equivalent • Participate in and contribute to product design/product feature discussions with engineering and development teams. • Analyze end-end performance, covering all tiers (Database, Network, Application server and client). • Analyze each tier in great depth and become a domain expert. • Create PSR engineering specifications, coding standards, optimization recommendations describing features for area of responsibility. • Optimize/suggest new coding patterns using efficient algorithms.
