• Utilize AWS security tooling and security services to support detection, prevention, and continuous improvement of cloud security posture.
• Identify, assess, and drive remediation of security risks and vulnerabilities in cloud infrastructure in partnership with engineering teams.
• Monitor cloud environments for threats, investigate suspicious activity, and respond to security alerts and events.
• Support incident response, penetration test findings, and security audit remediation, including containment, investigation, and post-incident follow-up.

• Deploy security technologies, including firewalls, intrusion detection systems, and access controls, while establishing device-level malware and antivirus standards to safeguard endpoints and cloud environments.
• Stay current on emerging threats, vulnerabilities, and compliance requirements, and apply best practices to strengthen overall security posture.
• Maintain security policies, documentation, and internal security standards.
• Support customer security reviews and respond to security questionnaires as needed.
• Act as Google Workspace administrator, managing access and account security.
• Support compliance initiatives such as ISO 27001 and SOC 2 as needed.
• Establish and maintain the company's AI usage policy, including approved tools, acceptable use guidelines, and data handling requirements for AI assistants, coding agents, and LLM-based services.
• Evaluate and vet AI tools (including coding assistants, agentic systems, and SaaS integrations with embedded AI) for security, privacy, and compliance risks before company-wide adoption.
• Define guardrails for AI use with sensitive data, customer data, and regulated information, ensuring alignment with SOC 2, ISO 27001, and customer contractual obligations.
• Educate engineering and non-technical teams on safe AI practices, including prompt hygiene, awareness of prompt injection and data exfiltration risks, and secure use of agentic tools perform actions within company systems.
• Monitor the evolving AI threat landscape (model supply chain risks, prompt injection, data poisoning, shadow AI usage) and update controls and policies accordingly.
• Review AI tool integrations in the DevOps lifecycle, including code generation, automated PR review, and agentic deployment tools, to ensure they meet security standards.

Experience:

• 5+ years of experience in information security, with at least 3 years concentrated on cloud security within AWS environments. Certifications (e.g., CISSP, AWS Certified Security Specialty, etc.) are preferred.
• Deep understanding of AWS architecture, security services, and best practices for securing cloud applications and data.

• Excellent analytical skills for identifying and mitigating complex security vulnerabilities and risks.
• Excellent communication skills with the ability to translate complex security topics for both technical and non-technical stakeholders.
• Organized and able to manage multiple priorities in a dynamic, fast-paced environment.
• A roll-up-your-sleeves mentality, eager to own, build, and execute security initiatives at all levels
• Experience developing or contributing to acceptable use policies and security guardrails for AI tools (coding assistants, LLM APIs, agentic systems) in a corporate or engineering environment.
• Familiarity with AI-specific risks including prompt injection, data leakage through model providers, model supply chain concerns, and the security implications of agentic tools with action-taking capabilities.
• Ability to evaluate AI vendors and their data handling practices (training opt-outs, data retention, regional processing) against compliance requirements.
