Working with the Global SOC, engineering and platform teams, agent owners, and governance stakeholders, you will strengthen AI incident response and embed practical security controls across a multi-AI environment.

What you will do

• Protect AI platforms, assistants, models, integrations, and autonomous agents from misuse, data leakage, excessive permissions, prompt-based attacks, insecure connectors, and emerging threats.
• Partner with the Global SOC to triage, investigate, contain, and learn from AI-related security incidents.
• Develop AI-focused monitoring, detection logic, threat-hunting approaches, response playbooks, and measurable control improvements.
• Identify and reduce exposure from unmanaged AI use, public agents, exposed credentials, risky integrations, insecure plugins, and over-permissioned identities.
• Assess AI applications, copilots, agents, models, retrieval systems, prompts, data sources, and third-party services through security reviews and threat modelling.
• Implement guardrails for identity, access, secrets, data handling, connector security, logging, monitoring, permissions, and human oversight.
• Maintain clear ownership, risk classification, findings, and remediation tracking, communicating progress to technical teams and senior stakeholders.

Who you are

• Experience in security engineering, cloud security, security operations, detection engineering, application security, or a closely related discipline.
• Practical knowledge of AI and agent risks, including prompt injection, data leakage, excessive agency, insecure tool use, identity abuse, secrets exposure, and supply-chain risk.
• Experience with Microsoft security technologies, cloud platforms, SIEM, EDR/XDR, identity, logging, and automation.
• Familiarity with enterprise AI services and developer tooling such as Claude, GitHub Copilot, Microsoft Copilot, and Agent 365.
• Ability to translate technical risk into implementable controls and work constructively with platform, engineering, and agent owners.
