Performance Engineer (Greenbelt, MD)
The Systems Engineer will develop models to ensure the performance demands for the Decennial Census are understood. Manage the development, review, communication, and change management associated with performance-related non-functional requirements. Models to develop and support include external demand models (demand models from the public and partners) as well as internal demand models (demand models between system components). A model is required for each stimulus source – external systems/users, internal systems/interfaces. Develop time allocation models for critical performance components. Develop Program-level scale-up plans to guide the scale-up activities of the Program and Projects. Develop and validate the Program-level performance plan. Identify needs and alternatives for system scalability, reliability, and availability and provide recommendations to the Program. Identify and document high level risks that may impact system performance.
Develop system sizing models for each system’s major components. These include networks, security devices, servers, storage, databases, memory, and operators. Consult with system teams on performance optimization and scaling strategies to ensure the systems can meet non-functional requirements for performance, scale and responsiveness. Review system designs to identify and remediate bottlenecks. Develop scaling strategies for systems and components. Validate modeling assumptions through testing and operational monitoring.
Duties and Responsibilities:
•Develops and maintains performance-related non-functional requirements (average/peak load, average response time, peak/average WIP, etc.)
