Position Overview 

We are seeking an experienced, hands-on Staff Security Engineer with deep expertise in securing large-scale cloud environments on AWS and GCP. The ideal candidate has spent years designing, building, and operating cloud security architectures and controls — IAM, network security, encryption, detection, and guardrails — and brings a working knowledge of securing AI/ML workloads as these become a growing part of our cloud estate. You will play a pivotal role in hardening our multi-account, multi-region cloud footprint and in extending proven cloud security practices to AI-powered services, including generative and agentic AI implementations. 

Primary Responsibilities 

• Design, implement, and operate cloud security architectures across AWS and GCP: organization/account structures, SCPs and organization policies, IAM and permission boundaries, KMS and encryption strategy, VPC design and network segmentation. 

• Build and maintain preventive and detective guardrails at scale — manage CSPM, security services (e.g., AWS Security Hub, GuardDuty, GCP Security Command Center), and automated remediation. 

• Embed security into infrastructure-as-code pipelines (Terraform, CloudFormation): policy-as-code, pre-deployment scanning, drift detection, and secure module patterns. 

• Secure container and Kubernetes workloads (EKS, GKE), including image supply chain, runtime controls, and workload identity. 

• Own vulnerability management across the cloud estate: continuous discovery and asset inventory, cloud-native and agent-based scanning (workloads, containers, serverless), risk-based prioritization using exploitability and reachability context (e.g., EPSS, KEV, internet exposure), and driving remediation with workload owners against defined SLAs. 

• Conduct security risk assessments, security design reviews, and threat modeling for cloud workloads, including AI/ML services and applications. 

• Extend cloud security controls to AI/ML platforms and services (e.g., AWS Bedrock, etc.): data protection, access control, endpoint and API security, and controls for agentic AI components such as MCP servers and tool integrations. 

• Develop and enforce security standards, policies, and baselines for cloud and AI/ML technologies, and drive their adoption across engineering teams. 

• Collaborate with DevOps, Platform, Data, and Engineering teams to integrate security throughout the SDLC and ML lifecycle. 

• Support monitoring and response for security incidents involving cloud and AI/ML infrastructure, ensuring rapid containment and remediation. 

Required Qualifications 

• Bachelor's degree or equivalent practical experience. 

• 10+ years of overall security engineering experience, including security assessments, security design reviews, and threat modeling. 

• 6+ years of hands-on cloud security engineering experience on AWS and/or GCP, with demonstrated depth in at least one and working proficiency in the other. 

• Proven proficiency designing and implementing cloud-native security controls at scale: IAM, KMS, VPC and network segmentation, encryption, logging and detection, and multi-account/multi-project governance. 

• Hands-on experience with infrastructure-as-code (Terraform, CloudFormation) and security automation. 

• Experience running cloud vulnerability management programs, including risk-based prioritization and remediation tracking across multi-account environments. 

• Working knowledge of AI/ML security risks — data privacy, model and endpoint security, prompt injection and related LLM threat vectors — and the ability to assess and quantify these risks using frameworks such as NIST AI RMF, OWASP Top 10 for LLM Applications, and MITRE ATLAS. 

• Excellent analytical, problem-solving, and communication skills. 

Preferred Skills 

• Certifications such as AWS Certified Security – Specialty, Google Professional Cloud Security Engineer, or CISSP. 

• Direct experience securing managed AI platforms, including guardrails, data isolation, and compliance automation for generative and agentic AI. 

• Familiarity with adversarial ML techniques (evasion, poisoning, model inversion/extraction, jailbreak testing) and responsible AI practices. 

• Experience with CNAPP, container security, and Kubernetes security tooling. 

• Experience working in agile, multicultural, and cross-functional teams. 

Soft Skills Required 

• Strong interpersonal skills with excellent written and verbal communication. 

• Uncompromising personal and professional integrity and ethics. 

• Clear articulation of complex technical concepts to both technical and non-technical stakeholders. 

• Creative and analytical thinking to navigate challenges and develop practical solutions. 

• Sound, risk-informed judgment — evaluating situations logically to make decisions and anticipate potential risks. 

• Effective prioritization and deadline management while managing multiple stakeholders.
