Job Title: Azure, Windows & Linux System Engineer

Location: Elkhart, IN

Contract Term: 6 Months (with possible extension based on performance)

**Hybrid – In-Office (Tues – Thurs)**

Job Summary

The client is seeking a skilled and meticulous Azure, Windows & Linux Systems Engineer to join our team on a 6-month contract basis, with the possibility for extension based on performance, to lead the implementation and rollout of a Managed Detection and Response (MDR), SIEM, and Endpoint Detection & Response (EDR) solution across enterprise environments. This role is responsible for deploying, configuring, and integrating Microsoft Sentinel and Microsoft Defender for Endpoint within hybrid infrastructures, ensuring scalable, secure, and compliant operations.

The ideal candidate will leverage automation (Ansible, PowerShell, Bash) to execute large-scale deployments across Windows, Linux, and operational technology (OT) environments. They will configure Azure components, including Log Analytics Workspaces, resource groups, RBAC, and service principals, and manage Sentinel data ingestion through Azure Monitor Agent (AMA), Data Collection Rules (DCRs), and syslog/CEF forwarders.

This role requires strong firsthand experience with Windows Server (2019–2025) and Active Directory, including Group Policy, service accounts, and RBAC troubleshooting, as well as Linux system administration (Rocky Linux, Ubuntu) for package management, system configuration, and firewall configuration. The engineer will also support Defender for Endpoint onboarding across Windows and Linux systems and ensure reliable syslog integration from network devices such as Check Point and Extreme Networks.

Additionally, the role requires awareness of PCI-scoped environments and adherence to security and compliance standards throughout the deployment lifecycle. The successful candidate will collaborate across infrastructure, security, and operations teams to deliver a resilient and scalable security monitoring platform.
