• Integrate performance tests, quality gates, reporting, and trend analysis into Azure DevOps pipelines and release workflows. 

• Use AI tools and agents to accelerate test design, maintenance, optimization, reporting, and coverage expansion. 

• Design and execute load, stress, endurance, spike, capacity, and scalability tests using realistic usage patterns. 

Analysis, Observability & Engineering Intelligence 

• Analyze application, API, database, infrastructure, telemetry, logs, and monitoring data to explain performance behavior. 

• Investigate latency, throughput, resource utilization, scalability, degradation, and reliability concerns. 

• Use AI-assisted analysis to identify trends, anomalies, bottlenecks, likely root causes, and recommended next actions. 

• Build dashboards, scorecards, KPIs, and decision-support reporting that connect technical performance to business impact. 

• Validate AI-generated findings through evidence-based analysis and partner with teams to confirm improvements. 

 

Technical Leadership & Team Enablement 

• Serve as a subject matter expert for performance testing, performance quality, and AI-assisted performance engineering. 

• Mentor engineers and testers on performance methods, tooling, automation, hands-on testing, and AI-enabled workflows. 

• Create reusable prompts, agents, workflows, examples, and accelerators that improve team productivity and consistency. 

• Promote responsible AI adoption while helping teams improve the way they test, analyze, and release software. 

 

What You Bring To The Table – Qualifications

Required 

• 7+ years of experience in software development, SDET, performance testing, software quality, or related engineering disciplines.
