QA Lead – Performance & Load Testing (AI-DLC)

Responsibilities

Performance and scalability engineering

  • Define the performance test strategy for the 2x, 3x and 5x targets: workload model, test types (load, stress, soak, spike, scale-out) and pass criteria.
  • Build realistic workload models from current claims patterns: nightly batch, EDI intake (837 claims, 277CA acknowledgements), real-time API calls and event traffic.
  • Design and run load tests on a production-sized Azure environment, and prove horizontal scale-out to 5x by adding resources rather than changing code.
  • Find and fix bottlenecks with the engineering pods across Go services, PostgreSQL, Kafka and the infrastructure.
  • Set performance budgets per service (throughput, latency, batch duration, error rate) and enforce them in CI/CD.
  • Publish load-test results as a go / no-go input to each production cutover.
  • QA architecture across the pods Own test standards, the automation framework and QA oversight across all six delivery pods.
  • Lead the Validation

pod

  • (2 Automation QA engineers).
  • Build automated tests from Gherkin acceptance scenarios, including API, integration, end-to-end and regression suites.
  • Design the parity tests that compare Prism's claim decisions with the legacy Que system, aiming for
  • 99.5
  • % decision match.
  • Support parallel runs, reconciliation
  • and UAT defect triage around each cutover.

AI-driven delivery (AI-DLC)

  • Use AI coding agents (GitHub Copilot and similar) to generate test cases, load scripts and synthetic test data from specifications.
  • Set review standards and quality gates for AI-generated tests and code, so AI output is checked before it is trusted.
  • Contribute to AI-DLC retrospectives: tune prompts, agents and the sizing model, and keep AI tool spend within budget.

Data and compliance

  • Work only with synthetic, non-production data offshore. No protected health information (PHI) reaches offshore staff or AI tools.
  • Define synthetic data volumes and profiles that are realistic enough for 5x load tests and repeatable for every release.

Requirements

  • 12+ years in QA, with 5+ years as a performance or QA architect on high-volume transaction systems (claims, payments, banking or similar).
  • Hands-on load testing with k6 (preferred), JMeter, Gatling or Locust, including scripting, distributed load generation and results analysis.

A track record

  • of capacity and scale-out testing: has designed and run tests that proved a system at several times its current volume, and can show the results.
  • Workload modelling from production patterns, covering both batch windows and real-time traffic.
  • Performance analysis across the stack: APM and observability (Grafana, Prometheus, Datadog, Dynatrace or Azure Monitor), PostgreSQL query plans and tuning, Kafka throughput and consumer lag.

Performance testing of

  • containerised, cloud-native services on Azure or another major cloud, including autoscaling behavior
  • Test automation architecture: framework design, API testing, BDD with Gherkin, and test gates in CI/CD pipelines (GitHub Actions or Azure DevOps).
  • Daily use of AI coding assistants (GitHub Copilot or similar) for test design, script generation or test data, with clear examples of reviewing and correcting AI output.
  • Experience leading QA engineers and setting standards across several agile teams.
  • Clear written and spoken English for daily work with US-based client stakeholders.

Preferred

  • US healthcare claims domain: claim lifecycle, payer submission, EDI X12 837 and 277CA, HIPAA.
  • Legacy-to-cloud modernization, especially strangler-pattern migrations with parallel runs and data reconciliation.
  • Parity or shadow testing that compares a new system's outputs with a legacy system's
  • Synthetic test data generation at volume.
  • Performance testing of Go services.
  • Chaos or resilience testing (failover, recovery, Kafka partition rebalancing).
  • Security testing in CI/CD, such as SAST with SonarCloud
  • Certifications such as ISTQB Advanced (Test Analyst or Technical Test Analyst) or a cloud certification such as Azure Administrator or Developer.
