Skills

  • Performance testing

Summary

Work Description:
  • Lead Performance Engineering: Manage the end-to-end performance testing process, from establishing baseline reports during development to lead-testing system capacity under peak loads.
  • Performance Baseline Reports (During Development & Unit Testing)
  • These reports establish expected response times, throughput, and resource utilization under normal conditions. They serve as a benchmark for future comparisons and help developers identify regressions early.
  • Load and Stress Test Results (During System Testing)
  • These deliverables simulate varying levels of user traffic to evaluate how the application performs under peak load and beyond capacity. They help uncover scalability issues, memory leaks, or infrastructure limitations.
  • Bottleneck Analysis and Recommendations (During Integration & Pre-Production)
  • Detailed diagnostics pinpoint slow database queries, inefficient code paths, or misconfigured servers. This analysis includes actionable insights for tuning application and infrastructure components.
  • Continuous Performance Monitoring Dashboards (During Deployment & Maintenance)
  • Integrated with CI/CD pipelines, these dashboards provide real-time visibility into performance trends across builds and environments. They support ongoing optimization and ensure SLAs are consistently met post-deployment.
  • Technical Authority: Lead the design and execution of high-scale orchestration (simulating 250,000 concurrent users) and the technical approach for bypassing MFA in automated environments.
 
Expectations:
A. Strategy & Planning
  • System specific Performance Test Strategy and Master Test Schedule covering PTAS plus Elections, Metro M5/Yard, JHS eMAR, TRUECredentials, PAO. (Update quarterly.)
  • Pre test readiness checklist (data, identities, quotas, observability, rollback).
B. Test Assets & Automation
  • Author/maintain scripts/configs in Azure Load Testing (Azure Test Cloud) and one of K6/JMeter/Gatling for top workflows; parameterize data; model ramp profiles and failover.
  • Build synthetic/anonymized datasets; provision non prod test identities under Security/IAM approved guardrails (no production MFA changes).
C. Scale Execution & Reporting
  • Run controlled peak load tests; deliver run report ≤5 business days post execution; publish RCA + remediation plan ≤7 business days for defects; update dashboards.
D. Cross Layer Troubleshooting & Remediation
  • Diagnose bottlenecks across application/API, DB/cache, F5 (VIPs/pools/iRules), and Azure (autoscale/quotas); open/track remediation tickets to closure.
E. Readiness Certificates
  • Issue system readiness sign off with thresholds met (response times, error rates, throughput, resilience/failover).
F. Knowledge Transfer
  • Maintain evergreen runbooks/playbooks (operations, troubleshooting, incident response); store in County repository.
 
Qualifications:
  • Proficiency in Performance Testing Tools (5+ Years of Experience)
  • Must have mastery of these tools to simulate realistic user loads, configure test scenarios, and generate actionable performance metrics.
  • Must have Key Skills: We expect these to be listed specifically on the resumes of candidates being submitted for the role.
  • Strong Programming and Scripting Abilities (8+ Years of Experience)
  • Custom scripting experience is required.
  • Deep Understanding of Web Architecture and Protocols (8+ Years of Experience)
  • Resource must have a solid grasp of how web applications function, and experience in designing accurate test scenarios and diagnosing performance issues at the network, server, or application layer.
  • Experience with CI/CD and DevOps Integration (5+ Years of Experience)
  • Must have experience integrating performance tests into the CI/CD pipeline.
  • Analytical Thinking and Monitoring Tool Proficiency (5+ Years of Experience)
  • Must have analytical skills and familiarity with monitoring tools to help identify bottlenecks, correlate metrics, and provide actionable insights for optimization to the County.
