About The Position

The Senior Security Architect (Enterprise and Emerging Tech) is a technical subject matter expert responsible for architecting, developing, and validating secure solutions across CAAT's hybrid cloud and AI-driven technology ecosystem. This role includes full-spectrum enterprise security architecture along with advanced focus on GenAI platforms, low-code/no-code AI tools, agentic AI systems, and machine learning pipelines. The incumbent will lead advanced security-by-design implementations, develop scalable security reference architectures, and implement end-to-end security testing frameworks around current enterprise infrastructure and emerging technologies.

Requirements

• Bachelor’s degree in Computer Science, AI, Information Security, Cybersecurity, or related technical field.
• 10 years of cybersecurity experience with a strong emphasis on hands-on security architecture and engineering for cloud and AI systems.
• Over 8 years of expertise in cloud security architecture and engineering, with a strong focus on Microsoft Azure services, governance models, secure API development, and the implementation of secure data and model validation pipelines.
• CISSP certification required.
• Excellent written and verbal communication coupled with solid technical skills
• Experience with Zero Trust architecture applied to AI environments.
• Expert-level hands-on experience with Microsoft Azure security services, configurations, and best practices.
• Deep technical knowledge of network security, application security, endpoint security, and data protection.

Responsibilities

• Develop and implement secure enterprise architectures by collaborating with cross-functional teams to align future-state roadmaps across network, platform, and application domains, with a strong focus on Microsoft Azure environments.
• Lead "security by design" initiatives across the full system development lifecycle, including threat modeling, architecture reviews, and risk-based control implementation in hybrid and AI-enabled platforms.
• Architect and deploy advanced Azure security solutions, including Microsoft Defender, Azure Sentinel, Key Vault, and identity/access management frameworks such as conditional access and privileged identity management.
• Conduct hands-on security assessments and penetration testing, creating and maintaining architecture artifacts like blueprints and security patterns while ensuring alignment with organizational cybersecurity strategies and frameworks.
• Implement and integrate security-by-design principles within CI/CD pipelines, configuring tools such as SAST, DAST, SCA, and IaC scanners to enable automated security testing and compliance throughout the SDLC.
• Lead secure DevSecOps practices by managing secrets, configuring security gates and approval workflows, and overseeing vulnerability management and remediation across deployment pipelines.
• Architect and implement secure-by-design frameworks for GenAI platforms, MLOps pipelines, and LLM integrations, including federated learning environments and agentic AI systems, with a focus on Azure, AWS Bedrock, and hybrid workloads.
• Define and enforce AI/ML-specific security controls such as model integrity, data lineage, drift detection, adversarial robustness, prompt injection mitigation, and secure integration of LLMs with RBAC and ethical AI considerations.
• Secure low-code/no-code AI platforms and third-party integrations, performing threat modeling (MITRE ATLAS, NIST AI RMF), assessing risks in APIs, vector databases, orchestration frameworks (e.g., LangChain), and supporting red/blue team readiness for AI-specific threats.
• Lead DevSecOps and compliance for AI systems, embedding security into CI/CD and ML pipelines, enabling continuous monitoring and telemetry for AI workloads, and supporting PCI-DSS, ISO 27001, and enterprise cybersecurity architecture initiatives.
