This position will be working with the Engineering Performance group to ensure the scalability and high performance of EMC Information Lifecycle Management products.
The successful candidate will be working with a group of highly motivated performance engineers to help build EMC ILM solutions for our most demanding enterprise class customers.
Job Responsibilities
Performance optimization projects require the individual to work closely with the development teams to: review designs for performance, analyze and propose solutions to application performance issues. Isolate problems, identify resolutions, and test changes to validate resolution.
Benchmark and trending projects involve developing application benchmarks within defined service level requirements. Ability to follow standard procedures and build reusable benchmark kits and processes to continuously validate performance enhancements from the development organizations. Developing single user and multi-user performance test software suites.
Design analysis projects involve "out of the box" thinking to find innovative solutions to potential performance problems during conceptual design phase. This position requires strong analytical and previous architecture work to identify potential issues before code is available for testing.
Performance problem resolution projects require in-depth architecture and application knowledge to resolve customer critical performance problems. Strong development and debugging on-the-spot skills are required.
Assisting in customer sizing and performance issues.
This position requires using and communicating Documentum's leading edge technology to business partners, prospects and customers. In addition to conducting tuning, architecture and benchmark projects you will also be responsible for:
