Job Description

Overview

Team Purpose

The Microsoft AI Infrastructure Information Security team protects the data, systems, services, and technology ecosystem that support AI development and operations at scale. You will help manage security and privacy risks across products, enterprise technologies, partners, suppliers, and third-party services by evaluating security maturity, identifying systemic threats, and providing technical guidance. Working across engineering, product, business, and security teams, you will help build scalable assurance practices that improve visibility, mitigate vulnerabilities, and support secure technology adoption.

Role Summary

As a Senior Security Engineer in the Microsoft AI Infrastructure Information Security team, you will lead large-scale security assessments of complex and high-risk applications, cloud services, artificial intelligence and machine learning services, application programming interfaces (APIs), developer platforms, infrastructure providers, and other third-party technologies. You will analyze evidence from multiple sources, lead architecture and design reviews, develop threat models, prioritize complex security issues, and drive mitigations that balance security and operational needs. You will also align stakeholders around security priorities and dependencies and advance the methodologies, automation, reusable patterns, and technical guidance used to provide security assurance at scale.

This opportunity will allow you to deepen your leadership in application, cloud, and enterprise security, advance scalable security-assessment and automation strategies, and expand your influence across multidisciplinary teams and technology partners.

Microsoft Culture Statement

Responsibilities

• Lead large-scale, end-to-end security assessments of complex technologies and integrations, including architecture and design reviews, threat modeling, penetration testing, vulnerability analysis, and control validation across applications, cloud services, APIs, AI services, developer platforms, and infrastructure providers.
• Analyze complex issues and technical evidence from multiple sources to identify trust boundaries, attack paths, data exposure, identity and privilege risks, software supply-chain weaknesses, and less common security threats; make informed tradeoffs and drive systemic issues to resolution.
• Evaluate products and services against security baselines, assess the impact of identified risks, and work with engineering, operations, research, and technology-provider leads to define and implement appropriate remediation or compensating controls.
• Provide security and architectural guidance throughout the development lifecycle, ensure relevant security design and development practices are in place, and develop reusable requirements, secure patterns, and best practices that prevent recurring issues.
• Build connections and agreements across engineering, product, business, partner, and security teams to clarify priorities and dependencies, communicate complex risk, incorporate customer and partner feedback, and escalate blocking issues when needed.
• Plan security analysis for large feature areas and multi-stakeholder reviews by accounting for product schedules, milestones, dependencies, risk assessments, and stakeholder effort while adapting plans as findings and business needs evolve.
• Lead clear reporting on findings, recommendations, risk, control effectiveness, and program outcomes; monitor and respond to security events, potential vulnerabilities, exposures, and policy-compliance issues.
• Create and drive adoption of mitigations, assessment methodologies, self-service resources, and readiness frameworks that improve security posture and enable informed decisions about third-party technologies.
• Architect and implement security tooling, automated workflows, and standardized processes, including appropriate uses of machine learning and generative AI, to expand coverage, improve vulnerability identification, validate controls, and reduce operational overhead.
• Maintain expertise across application security, cloud security, identity and access management, data protection, vulnerability management, incident response, and enterprise security tools, and share that expertise through guidance, coaching, and technical forums.
• Embody our culture and values
