This role designs scalable, secure, and observable integration patterns (API, event-driven, batch\/ETL, and hybrid) that enable product teams to deliver capabilities faster while reducing operational risk and integration cost.<\/p>\n\n\n\n<p>This role exists in a software or IT organization because modern product portfolios depend on a growing ecosystem of services, SaaS platforms, data stores, and third-party partners\u2014without a coherent integration architecture, delivery slows, reliability degrades, and security exposures increase.
