About The Position

DecisionPoint seeks a Performance & Resilience Test Engineer to evaluate the scalability, stability, responsiveness, failover behavior, and recovery capabilities of mission-critical software supporting the USMEPCOM ENLIST program. The position develops regression, API, integration, load, stress, endurance, and resilience tests; creates realistic workload models; and produces reproducible evidence of system behavior under normal, peak, degraded, and recovery conditions. The engineer works with architects, software developers, API and integration engineers, infrastructure and cloud teams, database specialists, cybersecurity personnel, CI/CD engineers, operations teams, and Government stakeholders. The role identifies performance bottlenecks, validates failover and recovery procedures, and provides evidence-based recommendations supporting release readiness, capacity planning, and operational resilience. The position is remote, with Chicago-area candidates preferred. Applicants acknowledge that their resume may be included in an active competitive government contract bid.

Responsibilities

Develop and maintain performance, load, stress, spike, endurance, volume, scalability, failover, and recovery tests.
Build automated regression, API, and integration tests for repeatable performance and resilience validation.
Analyze mission workflows, usage patterns, transaction volumes, concurrency, data characteristics, interfaces, and operational objectives.
Develop workload models representing normal operations, peak demand, surge conditions, degraded environments, and recovery scenarios.
Define test objectives, performance baselines, service thresholds, acceptance criteria, and measurable expected results.
Develop test plans, scenarios, scripts, data, configurations, and execution schedules.
Prepare representative test data for functional, high-volume, boundary, exception, failover, and recovery scenarios, and maintain repeatable test-data setup, refresh, reset, reconciliation, and cleanup processes.
Execute tests in development, integration, test, staging, performance, or other Government-approved environments.
Automate test execution through approved CI/CD pipelines where appropriate.
Produce reproducible test results, logs, reports, metrics, graphs, and objective evidence.
Measure and analyze response time, throughput, latency, concurrency, error rates, resource utilization, saturation, queue depth, and transaction completion.
Establish performance baselines and compare results across builds, releases, configurations, environments, and infrastructure changes.
Identify application, database, interface, network, cloud, infrastructure, configuration, or external-service bottlenecks.
Correlate test results with application logs, infrastructure metrics, traces, events, and monitoring data.
Work with technical teams to isolate root causes and recommend corrective actions.
Validate failover behavior for applications, services, interfaces, databases, infrastructure components, and dependent capabilities.
Test approved recovery procedures and confirm that services return to an acceptable operational state.
Validate recovery sequencing, data consistency, transaction handling, dependency restoration, and post-recovery functionality.
Evaluate behavior during component failures, network interruptions, service degradation, capacity constraints, and dependency outages.
Verify that systems fail safely and provide appropriate errors, alerts, retries, timeouts, and recovery behavior.
Support disaster-recovery, continuity, restoration, and operational-readiness exercises where applicable.
Document performance defects, resilience gaps, capacity risks, recovery failures, and release impacts.
Support defect triage, root-cause analysis, correction verification, and targeted regression testing.
Coordinate with architects and engineering teams to evaluate scalability, capacity, extensibility, and recovery approaches.
Coordinate with CI/CD engineers to integrate repeatable performance checks, thresholds, reports, and quality gates.
