• Collaborate with environment and data teams to ensure test readiness: appropriate 

environments, data sets, and automation pipelines. 

• Manage defect lifecycle: logging, prioritization, root cause analysis, retesting, and 

closure. 

• Drive continuous integration / continuous testing practices, working closely with 

DevOps and release teams. 

• Provide reporting on test execution, automation coverage, defects, and readiness 

metrics to leadership. 

• Promote best practices in test automation: code reusability, modularization, 

maintainability, and performance validation. 

• Ensure compliance with audit, controls, and regulatory requirements relevant to 

manufacturing and toy safety.

users, IT, and vendors in a global, matrixed environment. 

Preferred:
