Description:
Develops software solutions by studying information needs, conferring with users, and studying systems flow, data usage, and work processes. Investigates problem areas. Prepares and installs solutions by determining and designing system specifications, standards, and programming.
The Department of Information Resources (DIR) requires the services of One Performance engineer hereafter referred to as Worker, who meets the general qualification of Developer 3 Emerging and the specifications outlined in this document for Health & Human Services Commission – Social Services Applications team.
All work products resulting from the project shall be considered “works made for hire” and are the property of the HHSC. HHSC may include pre-selection requirements that potential Vendors (and their Workers) submit to and satisfy criminal background checks as authorized by the Texas law. HHSC will pay no fees for interviews or discussions, which occur during the process of selecting a Worker(s).
· Analyzes and evaluates application, system and ecosystem performance and scalability across multiple tiers with particular emphasis on the data tier in both cloud and on-prem environments.
· Identifies performance and scalability bottlenecks and issues and propose solutions to resolve the same.
· Simulates user/system traffic/load using scripts or other mechanisms, measure, evaluate and analyze component behavior.
· Optimizes code, queries, and system configurations to improve response time, scalability, and resource efficiency (CPU, memory, I/O).
· Analyzes and interprets Oracle wait events, AWR Raw data and trace and correlate observations and analysis to system behavior.
· Generates and analyzes AWR, ASH and ADDM reports.
· Extrapolates system behavior under representative load to predict system behavior under full load/stress.
· Extrapolates system behavior from application and data tier metrics.
· Communicates complex results, analysis, and metrics to diverse technical and non-technical audiences.
· Evaluates and predicts future performance needs based on application usage trends, traffic patterns, and growth projections.
· Conducts detailed root cause analysis (RCA) on performance issues to pinpoint the underlying cause of slowdowns or failures.
