Performance & Resilience Test Engineer, Journeyman

This is a fully remote position, open to applicants in Illinois.

📋 Description

• Design and sustain tests for performance, load, stress, spike, endurance, volume, scalability, failover, and recovery.

• Create automated regression, API, and integration tests to ensure consistent performance and resilience validation.

• Assess mission workflows, usage patterns, transaction volumes, concurrency, data characteristics, interfaces, and operational goals.

• Generate workload models for standard operations, peak demand, surge scenarios, degraded environments, and recovery situations.

• Establish test objectives, performance baselines, service thresholds, acceptance criteria, and measurable expected outcomes.

• Develop test plans, scenarios, scripts, data, configurations, and execution timelines.

• Prepare and manage representative test data for functional, high-volume, boundary, exception, failover, and recovery scenarios.

• Conduct tests in Government-approved environments and automate execution via approved CI/CD pipelines when applicable.

• Deliver reproducible test results, logs, reports, metrics, graphs, and objective evidence.

• Evaluate and analyze response time, throughput, latency, concurrency, error rates, resource utilization, saturation, queue depth, and transaction completion.

• Establish performance baselines and compare outcomes across builds, releases, configurations, environments, and infrastructure changes.

• Identify bottlenecks related to applications, databases, interfaces, networks, cloud, infrastructure, configurations, and external services.

• Correlate test results with application logs, infrastructure metrics, traces, events, and monitoring data.

• Collaborate with technical teams to pinpoint root causes and suggest corrective actions.

• Validate failover behavior and approved recovery processes.

• Assess recovery sequencing, data consistency, transaction management, dependency restoration, and post-recovery functionality.

• Examine behavior during component failures, network disruptions, service degradation, capacity issues, and dependency outages.

• Confirm safe failure behavior, appropriate errors, alerts, retries, timeouts, and recovery actions.

• Assist in disaster-recovery, continuity, restoration, and operational-readiness drills.

• Document performance defects, resilience gaps, capacity risks, recovery issues, and release impacts.

• Aid in defect triage, root-cause analysis, correction verification, and targeted regression testing.

• Coordinate with architects, engineering teams, CI/CD engineers, and operations teams regarding scalability, capacity, observability, failover, and recovery.

• Support Government demonstrations, user acceptance testing, release testing, and operational validation.

• Provide performance and resilience outcomes, residual risks, and release-readiness recommendations to stakeholders.

• Maintain test source code, scripts, configurations, data, and documentation in approved version-control repositories.

• Engage in sprint planning, backlog refinement, reviews, demonstrations, retrospectives, and release-readiness activities.

• Contribute to the ongoing improvement of performance engineering, workload modeling, observability, failover testing, and recovery validation.

• A minimum of six years of relevant professional experience.

• Experience in designing and executing load and performance tests.

• Proven background in developing realistic workload models based on user behavior, transaction volumes, concurrency, or operational demand.

• Experience in analyzing performance results and identifying bottlenecks in applications, integrations, databases, infrastructure, or networks.

• Familiarity with planning or executing failover tests.

• Experience in validating system, application, service, or data recovery.

• Capability to build or sustain regression, API, integration, and automated test coverage.

• Proficiency in preparing and managing representative test data.

• Ability to generate repeatable automated execution and reproducible test results.

• Competence in defining measurable performance baselines, thresholds, acceptance criteria, and expected outcomes.

• Proficient in correlating test results with logs, metrics, traces, events, or other observability data.

• Ability to document performance defects, resilience gaps, capacity risks, recovery failures, and impacts of releases.

• CompTIA Security+ CE or another Government-approved certification that meets the required IAT Level II qualification and current DoD 8140 work-role requirements, when necessary for assigned duties.

• Strong analytical, automation, troubleshooting, technical documentation, and communication abilities.

• Ability to work collaboratively with architects, developers, integration engineers, database specialists, infrastructure teams, cybersecurity personnel, CI/CD engineers, operations teams, and Government stakeholders.

• Preferred: recognized performance-testing, software-testing, cloud, or site-reliability certification.

• Preferred: experience with federal or Department of Defense programs.

• Preferred: background in mission-critical, regulated, security-sensitive, high-volume, or high-availability systems.

• Preferred: proficiency with performance-testing tools such as LoadRunner, JMeter, Gatling, k6, NeoLoad, Locust, or similar platforms.
