Senior Cybersecurity Architect; Cloud

The Senior Cloud Security Architect is a hands-on senior engineering position that designs, builds, deploys, and maintains security controls across commercial and government cloud environments, including Microsoft 365 Commercial and GCC High, Azure, AWS, and hybrid services. Its scope includes software, platform, infrastructure, virtual desktop, and approved cloud-based artificial intelligence services. The role leads technical design for complex work while remaining directly involved in configuration, infrastructure as code, deployment automation, testing, troubleshooting, control validation, and operational support.

A central responsibility is establishing and implementing the security patterns that allow the organization to adopt generative AI, machine learning, enterprise copilots, and agentic systems safely across commercial, government, and CUI environments. It applies government, defense-industry, privacy, and international security frameworks to practical technical designs. This role reports to the Senior Cybersecurity Architect & Senior Manager.

Cloud security engineering and design Design and implement security controls and reusable patterns across Microsoft 365 Commercial and GCC High, Azure, AWS, and hybrid services, including cloud guardrails, landing zones, workload protections, and virtual desktop environments.

Design and implement security architectures for generative AI, machine learning, enterprise copilot, and agentic systems, including secure access, data protection, identity, logging, content safety, and human-oversight controls.

Evaluate AI services and integrations for threats such as prompt injection, data leakage, excessive permissions, insecure model or plugin connections, and unauthorized use of sensitive or CUI data.

Establish reusable governance and technical patterns for the secure adoption, monitoring, testing, and lifecycle management of AI capabilities across commercial, government, and hybrid cloud environments.

Perform hands-on configuration, testing, troubleshooting, and tuning for complex cloud security implementations and platform integrations.

Build and maintain reusable infrastructure-as-code components and deployment automation for security policies, controls, and platform onboarding.

Lead focused design reviews and threat modeling for new services, major changes, and higher-risk use cases, then help implement the approved approach.

Cloud security platforms and operations Engineer and administer cloud security posture management and workload protection capabilities, including environment onboarding, policy configuration, security recommendations, coverage, alert integrations, and platform health.

Lead complex platform changes and escalations while sharing implementation, tuning, and support work with the Cloud Security Engineer.

Integrate cloud security telemetry with enterprise monitoring and response platforms and support escalated investigations when cloud expertise is needed.

Partner with Vulnerability Management on exposure prioritization and tracking and work with cloud platform owners on practical remediation approaches.

Government cloud and compliance engineering Design and validate technical controls that support CMMC and applicable NIST requirements, including NIST SP 800-171 and NIST SP 800-172.

Develop secure patterns for Microsoft 365 GCC High and CUI workloads that account for tenant and security boundaries, government-cloud service limitations, data handling requirements, and controlled connectivity with commercial environments.
