- Implement security best practices for Infrastructure as Code (IaC) and cloud-native environments
- Build and maintain security monitoring, log aggregation, and alerting systems to support detection and response
- Create security deployment checklists and continuously improve production environment security posture
- Assess and mitigate emerging risks introduced by AI technologies, including risks related to LLM applications, AI agents, prompt injection, data leakage through AI tools, model supply chain, and AI-assisted development workflows
- Partner with engineering teams to evaluate, adopt, and govern AI-powered development tools (e.g., AI coding assistants, AI agents) in a secure and compliant manner
