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
