We are looking for a Senior AI Security Engineer to join a high-growth technology team building AI-native products. This is not an offensive security role — we are looking for a defensive security engineer with a strong AppSec background (70%) and cloud security experience (30%), who is excited about applying their skills to the fast-evolving world of AI systems, LLMs, and autonomous agents.
You will be embedded in an engineering organization where AI is at the core of the product, working closely with engineering, product, and infrastructure teams to ensure that every AI integration, agent workflow, and LLM-powered feature is designed and deployed securely.
Key Responsibilities
Review AI architectures and integrations end to end — LLMs, AI agents, tool chains, APIs, and external connectors — identifying security risks before they reach production
Lead threat modeling sessions and security architecture reviews across the stack
Design, implement, and automate security checks and controls for AI systems, including input/output validation, guardrails, and runtime monitoring




Research and stay current on AI-specific attack vectors — prompt injection, model abuse, data exfiltration, jailbreaking — and translate findings into actionable mitigations
Enforce OAuth, IAM policies, and least privilege principles across cloud and AI integrations
Build and maintain security automation pipelines integrated into CI/CD workflows
Collaborate with developers on secure coding practices and security requirements for AI features
Contribute to internal security documentation, policies, and awareness
Requirements
5+ years of hands-on experience in cybersecurity — excluyente
Strong AppSec background: secure code review, SAST/DAST, dependency scanning, secrets management
Experience conducting threat modeling or security architecture reviews — excluyente
Solid understanding of OAuth, IAM, and least privilege design patterns — excluyente
Ability to read code and write scripts, ideally in Pytho
