Responsibilities:

• Design and implement enterprise-grade security architectures for AI, GenAI, and ML platforms, pipelines, and products (not just lead/define)
• Build and maintain automated security controls for LLM-based systems, agentic AI frameworks, and AI-driven APIs at scale
• Develop and operationalize CI/CD pipeline security, embedding automated security testing, validation, SAST/SCA, and monitoring into deployment workflows
• Lead threat modeling, red-teaming, and adversarial testing initiatives targeting AI systems, models, and data ecosystems
• Code and deploy security solutions to mitigate AI-specific risks: prompt injection, data leakage, model exfiltration, model poisoning, misuse detection
• Build secure AI data pipelines, implementing data governance, lineage protection, and privacy-preserving mechanisms end-to-end
• Define and implement secure identity, authentication, authorization, and trust models for human-to-AI and agent-to-agent interactions
• Develop infrastructure-as-code (IaC) security controls and secure-by-default cloud environments on Google Cloud Platform (GCP)
• Develop automation tools and scripts to reduce manual security toil and scale security operations
• Collaborate with platform, cloud, and infrastructure teams to integrate security into infrastructure provisioning and orchestration
• Influence enterprise security policies, governance frameworks, and regulatory compliance initiatives related to AI
• Mentor engineers; provide technical leadership and hands-on guidance across programs
• Stay at the forefront of emerging AI threats and translate insights into code, automation, and architectural improvements

Essential skills and/or Certifications:

• Bachelor's degree in Computer Science, Artificial Intelligence, Cybersecurity, or related field
• 8-12 years of relevant experience, including:
• 5+ years hands-on security engineering with demonstrated contributions to production systems

Technical Expertise:

• Strong programming proficiency in Python, Go, or Java - able to design, build, and maintain production security tools and integrations
• Expert-level DevSecOps skills: CI/CD pipeline security (GitHub Actions, GitLab CI, Jenkins), IaC scanning (Terraform, CloudFormation), SAST/SCA tools (Snyk, SonarQube, Checkmarx)
• Cloud security hands-on: Google Cloud Platform (GCP) including IAM policies, VPCs, Cloud KMS, secrets management, and GCP-native security services
• API security: Designing and securing API gateways, rate limiting, authentication mechanisms, and API threat models
• Distributed systems security: Microservices, service mesh (Istio, Linkerd), inter-service communication security
• Infrastructure security: Network segmentation, encryption (in-transit and at-rest), audit logging, secrets management (HashiCorp Vault, cloud vaults)
• Scripting & automation: Bash, Python for building monitoring, compliance, and remediation automation

Desirable:

• Experience with AI/ML platform security (LLMs, RAG architectures, vector databases, agentic frameworks)
• AI/ML security knowledge: threat models for LLMs, adversarial techniques (prompt injection, model poisoning), secure model serving architectures
• Experience with security compliance automation (CIS Benchmarks, NIST frameworks)
• Hands-on red-teaming or adversarial testing of AI systems
• Open-source contributions to security or DevSecOps tools
• Cloud security certifications (GCP Professional Cloud Security Engineer, GCP Associate Cloud Security Engineer)
• Experience with secure MLOps/ML lifecycle security

Soft Skills:

• Ownership mindset; solve problems proactively, be curious, take action
• Strong cross-functional collaboration in global, multi-stakeholder environments
• Excellent communication - translate complex security concepts for technical and non-technical audiences
• Mentorship and technical leadership capability
• Continuous growth mindset; commitment to staying current with AI security landscape
