## About the Role

7+ years in QA; strong experience in API/data automation and performance testing, * 7+ years of QA/test engineering for enterprise web/data applications.

 * Strong API testing experience and ability to validate REST services independently of the UI.
 * Strong SQL/data-testing skills for reconciliation, rule verification, migration validation, and troubleshooting.
 * Experience building maintainable automated regression suites using modern test frameworks.
 * Experience with performance/load testing for web APIs, file uploads, background jobs, or data-intensive applications.
 * Experience designing UAT plans, acceptance checklists, traceability, defect triage, and release-readiness evidence.
 * Ability to test XML/schema-based integrations and complex business-rule combinations.

Preferred Skills

 * Experience with Playwright/Cypress or equivalent UI automation, Postman/Newman/REST-assured or equivalent API testing, and k6/JMeter/Gatling or similar performance tooling.
 * Experience with GIS/spatial-data testing and regulatory reporting systems.
 * Experience embedding tests into GitLab CI/CD.

## Description

* Provide end-to-end quality ownership for a data-intensive application whose final acceptance is UAT-based. This role combines automation, API/data validation, functional testing, regression, UAT preparation, performance testing, and release readiness so the team does not need separate manual QA, automation, and performance resources., * Develop the master test strategy covering functional, API, integration, data, migration, security/authorization, regression, performance/load, and UAT support.
 * Build and maintain requirement-to-test traceability using the SOR requirement IDs and the validated requirements baseline.
 * Design test cases for each upload template, reporting reason, validation rule, duplicate scenario, staged approval, edit/retransform path, inspection/lifecycle function, role/organization access rule, search/report/export feature, and administration capability.
 * Automate high-value regression at the API/service layer and selected UI workflows; integrate automated tests into the team GitLab CI/CD pipeline where practical.
 * Perform database/data reconciliation testing across source upload, import, transformed, migrated, XML/submission and reporting outputs.
 * Validate NEIEN/XML against schemas and expected business outcomes; verify error handling maps failures back to the correct record/field.
 * Test CGP, TMDL IP/CEDS, OLAP, DCR/VACS and local-government integrations using real endpoints where available and mocks/stubs when necessary.
 * Coordinate GIS-related test cases with the GIS specialist for boundary conditions, coordinate validity, locality/HUC derivation, and spatial mismatch scenarios.
 * Design and execute load/performance tests for large uploads, asynchronous processing, search/export, APIs and expected concurrent provider activity; document thresholds, bottlenecks, tuning actions and retest results.
 * Develop the UAT plan, acceptance checklist, test-data guidance and defect triage process with the Lead BA and DEQ; support UAT execution and evidence collection.
 * Own defect lifecycle and release-quality dashboards; perform regression and readiness validation before each milestone release and go-live.
