Senior Service Engineer - Security Focused
Redmond, WA, USA
USD 119,800-234,700 / year
Help defend the network Microsoft runs on. Microsoft Digital's Network Defense Engineering (NDE) team in Redmond, Washington is hiring a Senior Security Engineer to help secure Microsoft's global network infrastructure.
Microsoft Digital (MSD) builds and runs the products and services Microsoft depends on. We pursue big ideas that drive transformational advances for Microsoft and its customers, and our engineers bring deep technical expertise and large-scale, first-hand experience to every problem we solve.
As a Senior Service Engineer - Security Focused on NDE, your focus is detection and response engineering for Microsoft's network. You will engineer the services that detect, contain, and respond to threats - secure configuration standards, network access controls, and control-plane protections, plus telemetry-driven detection built on vendor device CLI and large-scale data platforms such as Kusto (Azure Data Explorer). You will strengthen security orchestration and automated response, join the on-call rotation to drive incidents to resolution, and reduce manual toil through automation.
You will also support vulnerability management, configuration compliance, security reviews, and threat modeling, applying systems-level judgment to harden infrastructure and shrink the attack surface across networking and security teams.
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
- You will independently engineer and operate threat detection and response for Microsoft's network - detection engineering, threat hunting, security orchestration and automated response, including enforcement and containment actions - to mitigate threats.
- You will define and enforce secure configuration standards, access controls, and credential management; drive vulnerability management, configuration compliance, proactive security reviews, and threat modeling to reduce the attack surface across the device lifecycle.
- You will improve the development and operations of related systems and platforms - building and monitoring telemetry and analytics in Kusto (Azure Data Explorer) to surface patterns, detect anomalies, and strengthen AI-assisted detection, and delivering high-quality automation that reduces manual toil.
- You will take part in the on-call (DRI) rotation for major-impact incidents - leading triage, root-cause analysis, and enforcement actions - and coordinate multiple workstreams under pressure.
- You will follow prescriptive security, privacy, and compliance standards, and periodically support penetration testing, SOX compliance, and security audits.
- You will collaborate within and across teams - sharing insights and best practices, resolving cross-team conflicts, influencing security policy, and mentoring other engineers.
- Embody our culture and values.
