MEANINGFUL WORK AND PERSONAL IMPACT

This position will support the United States Postal Service (USPS) though:

• Security Architecture Vision: Lead the design of a global Zero Trust architecture, ensuring robust identity governance (IAM), network micro-segmentation, and data encryption across AWS, Azure, or GCP.
• AI-Native Security Strategy: Architect specialized security frameworks for AI/ML pipelines, focusing on data privacy for training sets, model integrity, and securing LLM-integrated applications against emerging attack vectors.
• Automated Guardrails (Policy as Code): Develop and enforce enterprise-wide security policies using Terraform, etc., ensuring that non-compliant infrastructure is automatically remediated or blocked from deployment.
• Cloud Posture Management: Design and oversee the integration of CNAPP and CSPM tools to provide real-time visibility into misconfigurations, vulnerabilities, and excessive permissions.
• Threat Modeling & Resilience: Conduct deep-dive threat modeling for complex cloud-native systems, simulating advanced persistent threats (APTs) and “blast radius” scenarios to strengthen system resilience.
• Security Consultancy: Act as the lead security advisor for the Cloud Architecture team, bridging the gap between DevOps agility and rigorous regulatory compliance (SOC2)., Core Objectives
• Zero Standing Privilege: Help Transition the organization to a “Zero Standing Privilege” model for all production environments.
• Automated Compliance: Help Achieve automated auditing for core compliance frameworks (e.g., NIST, CIS Benchmarks).
• Mean Time to Detect (MTTD): Utilize AI-driven monitoring to reduce the detection time of anomalous cloud activity to minimum
