Overview Security represents the most critical priorities for our customers in a world awash in digital threats, regulatory scrutiny, and estate complexity. Microsoft Security aspires to make the world a safer place for all. We want to reshape security and empower every user, customer, and developer with a security cloud that protects them with end to end, simplified solutions. The Microsoft Security organization accelerates Microsoft's mission and bold ambitions to ensure that our company and industry is securing digital technology platforms, devices, and clouds in our customers' heterogeneous environments, as well as ensuring the security of our own internal estate. Our culture is centered on embracing a growth mindset, a theme of inspiring excellence, and encouraging teams and leaders to bring their best each day. In doing so, we create life-changing innovations that impact billions of lives around the world. Microsoft Security's Getting Customers Ready for AI team is seeking a Senior Security Engineer with deep domain expertise to build and operationalize security-first systems that enable safe and scalable AI adoption. This role sits at the intersection of security engineering, AI systems, and enterprise readiness, focusing on transforming complex signals across identity, endpoints, data, applications, and infrastructure into actionable security insights, detections, and automated mitigation workflows. You will design and build end-to-end security systems that detect, prioritize, and respond to risks in AI-enabled environments-bridging traditional security controls with emerging AI-native threat models (LLM abuse, prompt injection, data exfiltration, model misuse). You will operate in a highly collaborative environment, driving execution from security signal ingestion and detection engineering to response automation and governance, helping customers achieve secure AI readiness at enterprise scale. Microsoft's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond. Responsibilities Security Detection, Investigation & Response Systems Design and build detection pipelines across identity, endpoint, data, and application signals to uncover vulnerabilities, misconfigurations, and active threats. Develop correlation engines and detection logic that combine multi-source telemetry into high-confidence security signals. Build and operationalize end-to-end detection validation prioritization remediation workflows. Implement automated incident response and remediation playbooks leveraging rule-based systems, workflows, and AI-assisted reasoning. Security Systems & Platform Engineering Architect and build scalable security platforms and services that process high-volume enterprise telemetry. Develop data pipelines and distributed systems for ingestion, enrichment, and real-time analysis of security signals. Integrate security capabilities into APIs, services, and platform layers to enable reusable and extensible solutions. Ensure systems are designed for reliability, performance, isolation, and security by design. Vulnerability Management & Risk Prioritization Build systems to discover and track vulnerabilities across cloud resources, identities, and application environments. Develop prioritization models that incorporate exploitability, impact, and business criticality. Enable workflows that drive end-to-end remediation closure, integrating with engineering systems and developer pipelines. Align with frameworks such as Defender, MDC, ASPM to enable holistic risk visibility and response. Security for AI Systems (AI-Native Threat Protection) Define and implement controls for AI-specific threat vectors (prompt injection, data leakage, model abuse, adversarial inputs). Build detection and mitigation mechanisms for LLM-based systems, RAG pipelines, and agentic workflows. Embed security into AI system design, inference pipelines, and orchestration layers. Contribute to responsible AI practices, governance, and secure deployment patterns. Data, Telemetry & Observability Build rich telemetry systems to track security posture, risk signals, and system performance. Develop analytics to measure detection effectiveness, false positives, and response outcomes. Leverage telemetry to enable continuous improvement loops across detection and response systems. Cross-Company Collaboration & Impact Partner with Engineering, Product, Data Science, and Security teams to translate security problems into scalable engineering solutions. Work across a matrixed organization to align signals, platforms, and response workflows. Help define security readiness standards and onboarding playbooks for enterprise AI adoption. Technical Leadership & Engineering Excellence Lead design and delivery of complex, large-scale security systems from concept to production. Establish best practices for secure coding, system design, reliability, and governance. Drive data-driven and evidence-based decision-making across security engineering initiatives. Mentor engineers and elevate the organization's security engineering maturity. Embody our culture and values.
