• Has skills to orchestrate release workflows and pipelines, and apply standardized pipelines via APIs to achieve CI and CD using industry standard tools (e.g., Jenkins, AWS/Azure pipelines, XL Release, others)
• Has skills to understand, report, and optimize delivery metrics to continuously improve upon them (e.g., velocity, throughput, lead time, defect leakage, burndown)
• Has skills to document and drive definition-of-done for requirements to meet both business and operational needs
• Understands how to build robust tests to minimize defect leakage by performing regression, performance, deployment verification, and release testing
• Has skills to conduct product demos and co-ordinate with product owners to drive product acceptance signoffs
