• Design and implement cloud security controls that reduce risk and improve prevention, detection, and response capabilities
• Contribute to securing multi-cloud and hybrid environments across AWS, Azure, GCP, and on-premise infrastructure
• Implement security controls for AI/ML workloads, including protecting data pipelines, model services, and AI-integrated applications
• Identify and help mitigate AI-specific risks such as prompt injection, data poisoning, and model/data leakage
• Apply DevSecOps and Infrastructure-as-Code (IaC) practices to integrate security into CI/CD pipelines
• Partner with product and platform teams to implement secure architecture patterns and cloud security standards
• Utilize CNAPP platforms and related tools to identify and remediate risks across cloud, container, and AI environments
• Implement and maintain security controls for containerized environments, including Kubernetes cluster configuration, image scanning, and runtime protection
• Support monitoring, detection, and response capabilities, including integration with cloud-native telemetry and security tooling
• Participate in threat modeling and risk assessments (Attack Surface Management, Data Security Posture Management, etc.) for cloud-native and AI-enabled systems
• Develop and maintain automation solutions to improve security coverage and operational efficiency
• Deploy and manage infrastructure using Infrastructure-as-Code (IaC) tools and best practices
• Contribute to security initiatives and projects, helping deliver measurable improvements to the organization’s security posture
• Support security operations and internal service requests, contributing to continuous process improvement

• Bachelor’s or Master’s degree in Computer Science, Information Security, or related field (or equivalent experience); typically 5–8+ years of relevant experience
• Experience designing and securing cloud and hybrid environments (AWS, Azure, GCP, On-Premise)
• Proficiency in one or more programming or scripting languages, with experience interacting with cloud APIs and automation workflows
• Strong understanding of cloud security fundamentals, including IAM, network security, encryption, and secure architecture design
• Experience implementing DevSecOps practices and securing Infrastructure-as-Code (IaC) workflows
• Experience deploying and securing container technologies (Kubernetes, Docker, EKS, GKE, AKS)

AI / ML Security Experience

• Understanding of security risks in AI/ML systems, including prompt injection, data poisoning, and model/data leakage
• Familiarity with data security principles in AI training and inference pipelines
• Experience implementing basic security controls, logging, and monitoring for AI-enabled services
• Awareness of AI security frameworks such as OWASP Top 10 for LLMs and NIST AI Risk Management Framework

Security Tooling & Operations

• Experience using CNAPP platforms to identify and remediate cloud security risks
• Familiarity with IaC scanning, cloud security posture management, and runtime detection tools
• Understanding of security prevention, detection, and response concepts

Additional Experience

• Experience building and securing scalable cloud architectures across application, network, and data layers
• Familiarity with serverless and event-driven architectures (e.g., AWS Lambda, GCP Cloud Functions, Azure Automation)
• Relevant certifications (e.g., AWS, Azure, GCP, Security+) are a plus
• Experience working in multi-OS and distributed environments
