About the position

The Oracle Database Performance Engineer will support a government client's project by identifying performance bottlenecks, optimizing database configurations, and analyzing system behavior to enhance performance and scalability. This remote position requires expertise in Oracle databases, particularly in performance tuning and analysis, to ensure efficient operation in both cloud and on-prem environments.

Responsibilities

• Identifies performance and scalability bottlenecks and issues and proposes solutions to resolve them.
• Simulates user/system traffic/load using scripts or other mechanisms, measures, evaluates, and analyzes 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, correlating 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.

Requirements

• Experience in analyzing and evaluating application performance across multiple tiers with emphasis on the data tier in both cloud and on-prem environments.
• Experience with identification and solution implementation for performance and scalability bottlenecks and issues.

• Experience extrapolating system behavior under representative load to predict system behavior under full load/stress.
• Experience with presenting complex results, analysis, and metrics to a diverse audience of technical and non-technical personnel.
• Experience with troubleshooting performance bottlenecks and issues.
• Knowledge of Oracle internals pertaining to database performance.
• Experience with understanding of application behavior, performance, and interaction patterns with DBs in relation to performance and scalability.
• Experience with extrapolating application and data tier metrics to explain system behavior.
• Experience with technical writing and diagramming skills, including proficiency with modeling and mapping tools (e.g., Visio, Erwin), and the Microsoft Office Suite (Word, Excel, and PowerPoint) and MS Project.
• Experience working with multiple teams concurrently, being able to prioritize and complete work on time with high quality.
