As a Staff Security Engineer focusing on Enterprise AI, the professional will spearhead the creation and management of security evaluation procedures for artificial intelligence and large language model systems. This position involves analyzing architectural designs, identifying risks unique to artificial intelligence, and establishing protective barriers that allow the enterprise to adopt these technologies safely.
The role requires close collaboration with internal departments including engineering, legal, privacy, compliance, and information technology. Suitable candidates possess a strong background in enterprise security, system threat modeling, and artificial intelligence frameworks.

- Design technical guardrails, authentication boundaries, and automated policy enforcement tools using Python and infrastructure-as-code
- Assess third-party SaaS vendors and corporate platforms for artificial intelligence capabilities and associated security risks
- Contribute to incident response documentation and act as a senior escalation resource for emerging artificial intelligence vulnerabilities
Requirements
- Demonstrated hands-on experience designing and maintaining security architecture for artificial intelligence and large language model applications
- Practical background in threat modeling against standard frameworks like the OWASP Top 10 for Large Language Model Applications
- Familiarity with agentic systems, Model Context Protocol servers, tool-permission models, and trust boundaries
- Experience building governance artifacts such as acceptable use policies and model risk assessments
- Proficiency with Python for building security tooling alongside infrastructure-as-code languages like Terraform
- Understanding of machine learning deployment concepts including retrieval-augmented generation, embeddings, and fine-tuning
Qualifications
- Prior experience operating within regulated environments meeting standards such as SOC 2 or PCI DSS
- Familiarity with applying identity and access management principles to non-human and agent identities
