About The Position

Design, develop, and automate performance testing solutions for multiple mobile applications, transitioning manual testing processes into unattended, cloud-based execution within UAT environments. Build and maintain repeatable load-testing scripts, configure automated tests using containers, CI/CD pipelines, and cloud infrastructure, and create scenarios that assess application performance across varying traffic conditions. Establish scheduled test runs, automated alerts, and threshold-based pass/fail criteria to support release readiness. Analyze test results with reporting and observability tools to identify bottlenecks, degradation, and capacity concerns. The role also includes implementing token-based authentication, expanding test coverage, coordinating with engineering and client stakeholders, and creating technical documentation and operational runbooks. Work within an accelerated delivery timeline to assess existing processes and implement automation improvements.
