Your Role:

We are seeking an AI Security Engineer to own the technical security controls for how Alpaca uses AI. The scope includes identity for AI agents and automations, security requirements for AI tools and integrations, guardrails, and security logging. You will also assist in developing AI-powered security tooling.

You will keep those controls consistent as AI adoption grows, and you will work with the teams building with AI so security is part of the design.

This role reports to the Enterprise Security Architect and works closely with AI Enablement, Engineering, DevOps, GRC, and the wider Security team.

The Security Team is 100% distributed and remote.

Things You Get To Do:

The core responsibilities of the AI Security Engineer are focused on AI access controls, secure AI platforms, guardrails, visibility into AI usage, and AI-powered security tooling.

AI Identity and Access Controls:

- Agent Identity: Define how AI agents, bots, and automations authenticate, what they can access, and how their actions are attributed and audited.

- Tool Access: Own security requirements for AI tool integrations, including least-privilege access and credential handling.

- AI Assistant Controls: Define and enforce security settings for approved AI tools, including data handling and access policy.
