• Develop and enhance validation systems and orchestration platforms to coordinate, execute, and track system-level validation workflows
• Design and execute performance and scalability tests, including workload modeling, throughput and latency analysis, and system bottleneck identification
• Develop and maintain performance testing tools, scripts, and datasets to simulate real-world customer workloads
• Execute and support release validation cycles, ensuring readiness of promoted builds
• Review product source code to inform test design, focusing on edge cases, failure scenarios, and performance bottlenecks
• Identify, document, and track defects, working closely with developers for resolution
• Partner with HealthShare scrum teams to gather validation requirements and translate them into scalable test strategies
• Collaborate with DevOps, Platform Engineering, and Operations teams to align infrastructure and validation workflows
