Windows Site Reliability Engineer

Windows Site Reliability Engineer

Location: Jersey City, New Jersey(Day 1 Onsite)

Contract-6 Months

Key responsibilities

Vendor application ownership

• Learn and document each vendor's application stack: client type (thin, thick, web), dependencies, databases, middleware, licensing and integration points.
• Act as the technical point of contact with vendors for releases, patches, defects and escalations, and hold them to agreed SLAs.
• Review vendor release notes and installers to assess risk and impact before any change reaches production.

Application packaging

• Package, repackage and customize Windows thick-client applications for silent, repeatable deployment (MSI, MST transforms, MSIX, App-V, PSADT wrappers).
• Resolve packaging issues such as dependencies, prerequisites, file and registry conflicts, and per-user versus per-machine installs.
• Maintain a versioned package library and distribute packages through SCCM/MECM or Intune.

Release and deployment

• Build and maintain CI/CD pipelines for vendor applications and their configuration (for example Azure DevOps, Jenkins or GitHub Actions).
• Promote releases through Dev, Test, UAT and Production with consistent configuration and documented rollback plans.
• Plan and run production deployments, including change requests, maintenance windows, smoke tests and post-deployment validation.
• Deploy and configure web applications on IIS, and thin-client apps on Citrix or RDS/AVD.

Post-production operations

• Own technology lifecycle management (TLM): track vendor support dates, plan upgrades, and retire end-of-life versions before support lapses.
• Define SLIs and SLOs, and build monitoring, alerting and dashboards for application health.
• Lead incident response and blameless root-cause analysis, and drive fixes with vendors and internal teams.
• Measure and reduce toil by automating repetitive work such as installs, configuration, health checks, certificate renewals and patching.
• Write runbooks and knowledge articles so support teams can operate each application independently.

Required qualifications

• [5+] years supporting enterprise Windows applications in an SRE, application support or systems engineering role.
• Hands-on application packaging experience: MSI/MST, MSIX or App-V, silent install parameters, and packaging tools such as Orca, InstallShield, Advanced Installer or PSADT.
• Software distribution with SCCM/MECM and/or Intune.
• Strong Windows Server and Windows client administration, including services, registry, permissions, Group Policy and Active Directory.
• Experience supporting thin-client (Citrix, RDS or AVD), thick-client and IIS-hosted web applications.
• Proven experience supporting third-party vendor software and working directly with vendor support and engineering teams.
• CI/CD pipeline experience with tools such as Azure DevOps, Jenkins or GitHub Actions, plus Git source control.
• Strong PowerShell scripting for automation and toil reduction.
• Experience deploying across lower environments and production under formal change management (ITIL or similar).
• Working knowledge of SQL Server sufficient to support application databases and troubleshoot connectivity and performance.
• Experience with monitoring and observability tools such as SCOM, Splunk, Dynatrace, Datadog or Azure Monitor.
• Clear written communication for runbooks, RCAs and vendor escalations.

Preferred qualifications

• Infrastructure as code and configuration management (Terraform, Ansible, PowerShell DSC).
• Cloud hosting experience for Windows workloads in Azure or AWS.
• Containerizing Windows or .NET applications, or MSIX app attach for AVD.
• Experience with vulnerability remediation and patch compliance for third-party software.
• Familiarity with SRE practices such as error budgets, toil budgets and capacity planning.
• Certifications such as Microsoft Certified: Azure Administrator, Endpoint Administrator, ITIL Foundation or Citrix CCA.
