JOB LOCATION: 3400 W Plano Pkwy., Plano, TX 75075

DUTIES: Responsible for partnering with the various Consumer Technology Experience (CTx), Development, Operations/Infrastructure, and Solution Architect teams in designing a comprehensive Performance Engineering framework based on the needs of the business. Responsible for planning, designing, and rolling out Performance Engineering Test solutions to avoid disruption and re-engineering costs through the early detection of defects by helping build Performance at the onset of a project. Directly responsible for cloud platform planning, creation, & maintenance of applications residing on our public cloud instances Possess expert level working knowledge of all key methodologies, strategies, technology, and experience of a performance & cloud engineer. Mentor junior level resources and be able to serve as a guide for peer team members in test engineering and quality strategic organizations. Design robust Performance Test Strategies that will validate impact of changes to performance of individual applications as well as the consumer technology ecosystem. Participate and provide recommendations for ensure Performance is built into the design of a solution. Work closely with Vendor/Partner teams for execution of load tests based on software delivery/release schedule. Review performance test results and ensure all aspects of infrastructure and application responsiveness are evaluated for delivery to production. Provide key SME leadership within Consumer Quality Engineering (CQE) team on Transformative Efforts and implement the best industry practices to Performance Testing. Design and implement automated Performance Testing in the CI/CD pipeline. Define and implement post-mortem / root-cause analysis processes – develop improved testing scenarios based upon analysis. Performing workload, future growth analysis and application endurance certification through automated client scripts using performance assurance tools for automating applications user flows. Implement an automated utility to capturing application transaction traces, sessions, browser network logs, response time for each action performed on the application which will further validate the captured data with the data injected in ELK and Dynatrace for the application flow. Understand the application, technologies and onboard a new application by testing and validating them in lower environments. Identify the gaps/anomalies and provide root cause for the issues identified. Work with vendor support and provide required details for resolution of issues or enhancements needed for application. Work with the application team to capture additional metrics, meta data from the application pages. Work with the application team for code changes where manual injections are needed. Develop documentation (as required) on new or existing systems. Ensure systems meet documented user requirements. Participate in identification, analysis, and resolution of identified issues. Building service simulations of project blocking and overhead services on private premises cloud using Broadcom Dev Test Service Virtualization and Mock Server after analyzing the artifacts generated by interaction pointers which will unfold the overlooked dependencies on both application and process level. Create hypothesis based on production outages in reactive approach. Design chaos scenarios for critical applications in a proactive approach. Execute various chaos scenarios using Gremlin tool to target System Resources (CPU, Memory, Disk & IO), System State (Process killer, Shutdown & Time travel) and Network (Blackhole, DNS, Latency & Packet loss) to test the resiliency of the application. Provide recommendations based on chaos experiments analysis. Collaborate with other teams, including developers, operations, and security, to understand the system's architecture and identify potential weaknesses. Conduct a detailed volumetric analysis and derive a Workload Model.
