Key job responsibilities The Systems Engineer contributes to the design, implementation, and automation of complex Windows infrastructure solutions across multiple environments. This role supports the infrastructure automation, system architecture, and Windows environment management, focusing on developing automated solutions for managing large server fleet. - Provide technical support for Windows Server infrastructure systems and Active Directory services - Perform system maintenance, updates, and patch management for Windows environments - Develop and implement automation solutions for routine support processes using PowerShell and other scripting tools - Maintain accurate documentation of all support activities, and contribute to knowledge base and runbook development - Participate in on-call rotation to ensure 24/7 system availability A day in the life Your morning starts with a review of overnight automation runs. The Infrastructure as Code deployment you scheduled has completed successfully — fifty servers provisioned, configured, and domain-joined without a single manual touch. You verify the results, make a minor template refinement, and commit the update to the repository. Mid-morning, you're deep in an Active Directory architecture session. A new security domain is being stood up, and you're designing the domain controller topology, trust relationships, and Group Policy structure that will govern it. You sketch the architecture, validate it against security requirements, and begin translating your design into automated deployment scripts. After lunch, a junior engineer pings you for guidance. They're building a PowerShell workflow to automate a recurring maintenance task, and they've hit a logic challenge. You pair with them for twenty minutes, guiding them toward a cleaner approach while explaining the "why" behind your suggestions. They push their updated code with confidence. Later, you're tackling a scalability challenge for the enterprise meeting room infrastructure. The current solution works, but it won't scale to the next phase of growth. You prototype an automated provisioning approach that can handle ten rooms or a hundred with the same template — and document it so the team can extend it further. Before wrapping up, you review a pull request from a teammate, run a quick validation on a Python automation script you've been developing for fleet-wide patching, and update the team's technical roadmap with progress on your current initiative.
