Ensure architectural decisions incorporate regulatory, customer, and audit requirements (ISO/IEC 27001, SOC reporting, BSI C5, NIST, CIS Benchmarks, MITRE ATT&CK, CSA CCM), and are evidenced through pattern adoption and architecture reviews. Partner closely with IT and CloudOps to embed security controls, influence technology decisions, and ensure alignment to security strategy. Engage with senior stakeholders (CISO, CTO, CIO, Product & Cloud leadership) to shape cyber direction and ensure architectural consistency across teams. Cloud & Infrastructure Security Secure architecture for multi‑cloud environments (Azure primary; awareness of AWS/GCP) across networking, compute, data, containers, and serverless.
