Cloud Security Engineer/Architect (Remote)

Tier One Technologies is seeking a Cloud Security Engineer/Architect to support a U.S. Government client. The role leads Zero Trust and AI-native security architecture, cloud posture management, automated compliance, threat modeling, and security automation across major cloud platforms.

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

• Mastery of cloud-native security suites (e.g., AWS Security Hub, Azure Defender, GCP Security Command Center)
• Expert knowledge of Identity-First Security, including CIEM, Just-In-Time (JIT) access, and complex OIDC/SAML flows
• Proficiency in Python, Go, or Bash to build custom security automations and integrate with SOAR platforms
• 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
• Proven ability to influence technical roadmaps and present security risks clearly to C-suite stakeholders
• Must be a US Citizen or Permanent US Resident (Green Card Holder)
• Must be able to obtain Public Trust Clearance
• Must have lived in the United States for the past 5 years
• Cannot have more than 6 months travel outside the United States within the last five years. Military Service excluded. (Exception does not include military family members.)
