We are part of the Windows Servicing and Delivery (WSD) team in the Experiences + Devices division. Our mission is simple but critical: keep customers secure and productive by delivering a reliable, high-quality servicing experience across current and future versions of Windows.

The Customer Focused Engineering (CFE) team within WSD is seeking Senior Software Engineers to join us in this mission. In this role, you'll work on core components of the Windows operating system—specifically focusing on Active Directory and identity-related infrastructure.

You will contribute to:

• Investigating and fixing security vulnerabilities across print and networking stacks.
• Addressing non-security bugs and servicing issues that impact customer environments.
• Reproducing and resolving customer-reported incidents (ICMs) in collaboration with support and product teams.
• Driving engineering quality and compliance through rigorous debugging and validation.
• Ensuring reliable, regression-free fixes across diverse hardware, protocol stacks, and deployment scenarios.

This role is ideal for engineers who enjoy deep system-level debugging, protocol correctness, and delivering impact at scale by keeping the Windows ecosystem secure and reliable for millions of users.

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.

• Investigate and fix security vulnerabilities in Windows Print or Networking components, ensuring all related variants are addressed.
• Reproduce, debug, and resolve customer-reported issues (ICMs) across a wide range of print and networking configurations.
• Deliver high-quality, compatible fixes with minimal risk to system stability or application behavior.
• Address non-security bugs as part of regular servicing commitments for supported Windows releases.
• Collaborate with escalation engineers, support teams, and feature owners to drive resolution of complex issues.
• Maintain strong engineering standards through code inspection, validation, and testing practices.
• Continuously look for opportunities to improve servicing tools, diagnostics, and triage processes.
• Provide technical guidance and mentorship to junior team members.

Required Qualifications:

• 8+ years of professional software development experience.
• Proficiency in C++, with experience working in large and complex codebases.
• Strong debugging and problem-solving skills, especially in multi-threaded, system-level applications.
• Experience with Windows system-level programming, ideally in areas related to print subsystems, networking protocols (e.g., TCP/IP, SMB, RPC), or driver models.
• Familiarity with Windows debugging tools (e.g., WinDbg, trace logs, protocol analyzers like Wireshark).
• Proven ability to understand and troubleshoot unfamiliar codebases.
• Strong verbal and written communication skills.
• Ability to work across global teams and collaborate in a diverse, team-oriented environment.
