This includes supporting automation, configuration management, and operational improvements that enhance stability, security, and operational efficiency across the VINCI environment. This may include assisting with infrastructure-as-code workflows, automated build and deployment activities, monitoring integrations, patching, vulnerability remediation, and system hardening aligned with federal or enterprise security standards.

Experience supporting automation or scripting activities using tools such as PowerShell, Bash, Azure DevOps, or Jenkins
Ability to support infrastructure-as-code, configuration management, or automated deployment workflows for server configurations, patches, baselines, or environment-specific parameters
Ability to perform regular patching, vulnerability remediation, system hardening in accordance with federal or enterprise security standards, document system configurations, operational procedures, and troubleshooting steps
Ability to work independently with application, infrastructure, and security teams to troubleshoot issues and support operational needs
Ability to obtain and maintain a Public Trust or Suitability/Fitness determination based on client requirements
HS diploma or GED

Nice If You Have:

Experience supporting enterprise infrastructure environments, including servers, storage, backup, and monitoring platforms
Experience supporting regulated or government environments, including compliance with federal security and audit requirements
Experience administering RHEL, CentOS, and Linux-based SAS 9.x environments
Experience supporting Hadoop 3.x platforms in enterprise or analytical environments
Experience with Microsoft Forefront Threat Management Gateway (TMG) and enterprise perimeter security controls
Knowledge of storage networking concepts, SAN architectures, and performance optimization
Ability to maintain and troubleshoot IIS-based application hosting, including bindings, SSL management, and application pool health
Ability to develop and maintain PowerShell DSC, GPO templates, and baseline configuration modules that feed into automated deployment workflows
Ability to integrate Windows systems into automated configuration drift detection, compliance reporting, and remediation pipelines
Possession of strong scripting and automation skills using tools such as PowerShell and Bash
