  • SELECTED CANDIDATES WITHOUT REQUIRED CLEARANCE WILL BE SUBJECT TO A FEDERAL GOVERNMENT BACKGROUND INVESTIGATION TO RECEIVE IT.
Responsibilities:
  • 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).
  • 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

  • Deep expertise embedding automated security testing (SAST/DAST/SCA) directly into CI/CD pipelines.
  • Advanced understanding of secure connectivity, including SD-WAN, Cloud WAF, and Zero Trust Network Access (ZTNA).
  • Strong ability to bridge the gap between "Speed of DevOps" and "Rigors of Security" while communicating clearly with executive leadership.
