Senior Windows Server Systems Engineer ( 3-6 years) , Bangalore

As a Senior Windows Server Engineer, you will build, implement, and maintain the Windows Server platform across a large-scale environment (3,000+ servers). You will execute the patching, imaging, deployment, and virtualization standards for the fleet - turning architecture and design into working, reliable infrastructure. This is a hands-on senior engineering role focused on Windows Server, not an endpoint/desktop or help-desk operations role. You will own implementation and complex troubleshooting, and serve as a strong technical contributor rather than the fleet-wide design authority.

• Implement and maintain the enterprise patching solution (SCCM/MECM or equivalent) across 3,000+ servers, including running patch cycles, monitoring compliance, and remediating failures
• Build and maintain Windows Server gold images against established baselines; test, validate, and publish image updates
• Execute standardized server deployments and provisioning workflows; ensure new builds conform to platform standards
• Operate and support server virtualization on Hyper-V (preferred) and/or VMware - VM provisioning, host maintenance, and troubleshooting
• Monitor and report on patch compliance against SLAs; drive remediation of non-compliant hosts
• Support vulnerability remediation by working from scanner output (Qualys, Tenable, Rapid7) and applying patches and hardening fixes
• Develop and maintain automation for patching, provisioning, configuration, and reporting using PowerShell
• Perform advanced troubleshooting and root-cause analysis on Windows Server issues across the fleet
• Support Active Directory-related server tasks (domain-join automation, GPO application, DNS) as they apply to server infrastructure
• Contribute to standards and documentation, and provide guidance to junior engineers and operations staff

Required Skills & Experience

• Strong hands-on experience administering Windows Server (2016/2019/2022 and newer) at scale
• Practical experience operating an enterprise patching/configuration tool such as SCCM/MECM (Current Branch) or comparable
• Experience building or maintaining Windows Server images and executing standardized deployments
• Working knowledge of virtualization: Hyper-V (preferred) and/or VMware vSphere - provisioning, maintenance, and troubleshooting
• Proficient PowerShell scripting for automation and reporting; exposure to Infrastructure-as-Code or configuration management (DSC, Ansible, Terraform) is a plus
• Solid Active Directory, GPO, DNS, and Windows networking fundamentals
• Familiarity with vulnerability scanners (Qualys, Tenable, Rapid7) and security hardening baselines (CIS, DISA STIG)

General Skills & Competencies

• Self-directed and able to manage assigned workstreams with limited oversight
• Strong troubleshooting mindset and attention to detail under SLA pressure
• Clear written and verbal communication; able to document work and explain technical issues to peers and leadership
• Collaborative team contributor; mentors junior staff and shares knowledge
• Keeps current with Windows Server and virtualization technologies

Experience Required

• 6+ years in Windows Server infrastructure engineering, including hands-on work with enterprise patching, imaging, and virtualization at scale (hundreds to thousands of servers)

Certifications Preferred

• Microsoft Certified: Windows Server Hybrid Administrator Associate (AZ-800/AZ-801)
• Microsoft Certified: Azure Administrator Associate (AZ-104) - for hybrid/cloud environments
• VMware VCP-DCV or equivalent Hyper-V/virtualization credential
