This role creates enterprise-grade reliability architectures (SLOs\/SLIs, observability, incident response, capacity, resilience engineering, and automation standards) and ensures those architectures are adopted consistently across product and platform engineering teams.<\/p>\n\n\n\n<p>This role exists because modern software and cloud-native platforms require intentional design for reliability and operability\u2014not just feature delivery\u2014and because reliability outcomes (availability, latency, recoverability, and change safety) depend on cross-cutting architectural decisions.
