Basic Qualifications Significant experience in technical program management, product management, engineering management, or a related technical leadership role. Experience leading complex, cross-functional programs involving APIs, platform products, enterprise integrations, or developer-facing systems. Strong understanding of marketplace, e-commerce, catalog, seller platform, or retail technology domains. Experience working with external partners, enterprise customers, system integrators, ERP providers, or large-scale API consumers. Demonstrated ability to translate business objectives into technical requirements and execution plans.
