• Compliance as Code: Lead the translation of complex regulatory requirements (NIST SP 800-53, FedRAMP, CMMC) into technical controls, authoring and enforcing security policies within IaC (Terraform) templates.
• Identity and Access Architecture: Develop and govern the enterprise IAM strategy, leveraging Workload Identity, Just-In-Time (JIT) access, context-aware controls, and MFA/CAC/PIV integration.
• Data Protection & Encryption: Define the strategic vision for data protection, designing key management strategies across Cloud KMS/HSM/EKM and architecting data encryption protocols to secure data at-rest and in-transit.
• Network Security Design: Oversee the architectural design of network security controls, including VPC Service Controls, Cloud Armor policies, and firewalls, to mitigate data exfiltration risks.
• Technical Leadership: Act as the primary technical advisor and final point of escalation for cloud security risks, threat models, and architectural design decisions. Mentor engineers and developers on secure cloud practices.
• Security Automation: Architect secure, automated telemetry and audit logging pipelines that route seamlessly into SIEM systems (e.g., Google Security Operations/Chronicle).
