What are the responsibilities and job description for the Windows Site Reliability Engineer position at Vy Systems?
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.
