Summary:

The Cloud Security Engineer is responsible for protecting the organization's cloud environment by designing, implementing, and maintaining security controls across Microsoft Azure, Microsoft 365 (M365), and Dynamics 365 (D365). This role focuses on cloud security posture management, cloud workload protection, identity and access management, and data protection within Azure and Microsoft cloud services. The engineer will harden cloud configurations, apply zero-trust principles, secure cloud-native workloads and SaaS applications, and partner with IT, Dev Ops, and Compliance teams to ensure that cloud operations remain resilient, scalable, and aligned with regulatory requirements.

Essential Duties and Responsibilities:

• Design, configure, and maintain security controls across Microsoft Azure, including IaaS, PaaS, and SaaS workloads, ensuring secure deployments and continuous posture management.
• Configure and maintain security across all Azure resources (e.g., virtual machines, virtual networks, storage accounts, Azure Key Vault, App Services, Azure SQL), while continuously improving cloud security baselines and configurations.
• Apply zero-trust principles to cloud workloads and SaaS applications, including micro-segmentation, least-privilege access, and continuous verification across Azure, M365, and D365.
• Deploy and manage Microsoft Defender for Cloud and Microsoft Defender XDR to monitor cloud security posture, detect misconfigurations, and remediate vulnerabilities across multi-cloud and hybrid environments.
• Conduct gap analyses against relevant cloud security standards (e.g., NIST, CIS Benchmarks for Azure/M365, SOC 2, PCI-DSS) and recommend remediations.
• Maintain records of audit findings and track resolutions to ensure ongoing cloud compliance.
• Develop and maintain cloud security standard operating procedures (SOPs), reference architectures, and best practices.
• Collaborate with cross-functional teams (Infrastructure & Operations, Dev Ops, Compliance) to disseminate guidance on secure cloud development, infrastructure-as-code (IaC), and operational activities, ensuring that new or updated cloud systems adhere to security best practices.
• Create and update knowledge base articles, runbooks, and incident response playbooks to standardize and streamline cloud security procedures.
• Oversee the security configurations within M365 and D365, including data loss prevention (DLP), Microsoft Purview information protection, conditional access, threat protection (Defender for Office 365, Defender for Cloud Apps), and update the cloud security roadmap as needed.
• Deploy and tune cloud-native protections including Azure Web Application Firewall (WAF), Azure Front Door, Azure DDoS Protection, and advanced threat analytics in coordination with internal teams and external vendors, and guide them through production rollout.
• Develop and maintain incident response protocols for cloud environments to ensure timely identification, containment of threats, and implementation of preventive measures.
• Configure and manage cloud security monitoring tools such as Microsoft Defender for Cloud, Microsoft Sentinel, Rapid7, and other SIEM/SOAR platforms to detect anomalies, suspicious activity, and potential attacks across Azure, M365, and D365.
• Evaluate and secure containerized workloads (e.g., Azure Kubernetes Service), serverless functions, and Dev Sec Ops  pipelines, embedding security into CI/CD processes.
• Provide guidance and expertise in cloud architecture reviews, cloud security risk assessments, and…
