Sr Cloud Security Engineer

PlanIT Group, LLC is recruiting for a Senior Cloud Security Engineer to secure a large hybrid ecosystem involving over 30,000 physical sites and multiple cloud tenants. The role focuses on implementing automated security guardrails, threat detection, compliance automation, and AI/ML security governance to ensure robust protection across private data centers and public cloud environments.

Responsibilities:

• Security Posture & Compliance Automation: Design and implement automated compliance assessments to enforce hardening standards (CIS, NIST) across cloud accounts and on-premises virtualized environments
• Asset & Data Security: Architect and maintain the security of our sprawling asset inventory. Implement data-at-rest and data-in-transit encryption strategies that span from physical data center servers to cloud-native storage
• Identity & Fraud Mitigation: Develop and secure the "Identity Fabric" linking 600k+ employees and millions of commercial customers. Collaborate with Fraud teams to integrate signals from SIEM and Databricks to detect and block malicious account activity
• Hybrid Engineering: Build and manage secure connectivity (Transit Gateways, Service Mesh) between on-premises hypervisors and multi-cloud environments, ensuring consistent policy enforcement
• Threat Detection & Response: Partner with the SOC to develop high-fidelity detection logic. Build SOAR playbooks that automate the isolation of compromised cloud workloads or on-premises VMs
• Efficacy Assessment: Support ongoing "Purple Team" exercises and control testing to validate that security tools (EDR, WAF, DLP) are performing as intended across all tenants
• AI/ML Security Governance (Adversarial Defense): Establish security guardrails for the enterprise's internal and customer-facing AI models. This includes protecting Databricks training pipelines from data poisoning and implementing mitigations for LLM-specific threats like prompt injection and sensitive data leakage
• Hyper-Automation of Security Operations: Drive the transition from manual "click-to-operate" security to Autonomous Security Operations. This involves building advanced SOAR playbooks that use ML-based triggers to perform auto-remediation across hybrid environments without human intervention
• Business Process Streamlining: Partner with business units to integrate security "invisibly" into their workflows. Use automation to reduce "security friction" in logistics and retail operations, ensuring that compliance checks (like PCI or SOC2) are performed continuously and programmatically
• AI Asset Management: Client and catalog "Shadow AI" usage across the enterprise, ensuring all third-party AI tools meet the enterprise's privacy and security standards

Requirements:

• Expert-level knowledge of security architectures in AWS, Azure, and Google Cloud
• Mastery of Terraform, Ansible, or CloudFormation to deploy and manage security configurations at massive scale
• Ability to leverage Databricks to perform deep-dive analysis on billions of logs for threat hunting and efficacy reporting
• Experience securing Kubernetes (EKS/AKS/GKE) and Docker environments, focusing on runtime protection and image integrity
• Proficiency with OAuth 2.0, SAML, and CIAM solutions for large-scale customer and employee authentication
• Proficiency in using Python (PySpark/Pandas) within Databricks to build custom anomaly detection models that go beyond standard SIEM correlation rules
• Knowledge of the OWASP Top 10 for LLMs and experience implementing AI gateways or 'firewalls' to monitor and filter AI-generated traffic
• Deep expertise in building 'glue code' that connects disparate COTS and custom applications via secure, automated APIs to streamline cross-functional business activities
• The ability to explain to non-technical stakeholders how AI-driven security decisions (like blocking a suspicious $1M commercial transaction) are made and how to handle 'false positives' at scale
• A relentless focus on identifying repetitive manual tasks (e.g., firewall rule reviews, access audits) and replacing them with self-healing, automated systems
• 8+ years in a technical Cybersecurity Engineering role, with at least 4 years focused on large-scale cloud or hybrid environments, and a portfolio of projects where AI or Machine Learning was directly applied to solve security or operational scaling problems
• B.S. or M.S. in Computer Science, Information Security, or a related technical field required
• Demonstrated experience managing environments with 10,000+ workloads and high-availability requirements for retail/commercial applications
• Experience with CI/CD and GitOps workflows, treating security configurations as code that is automatically tested and deployed
• Pass a client mandated clearance process to include drug screening, criminal history check and credit check
• All candidates must be a US Citizen or permanent status Green Card holder
• Cannot have more than 6 months travel outside the United States within the last five years. Military Service excluded
• CISSP (Certified Information Systems Security Professional)
• CCSP (Certified Cloud Security Professional)
• Cloud-specific Professional Security Certifications (e.g., AWS Certified Security – Specialty or Google Professional Cloud Security Engineer)
