This is a hands-on, execution-focused role that spans Microsoft cloud services, on-premises infrastructure, system automation, and internal tooling. The ideal candidate is a self-directed technical professional who takes pride in keeping systems running cleanly, brings a proactive mindset to identifying and resolving issues before they impact the business, and is motivated by the opportunity to grow alongside a team of strong engineers in a Microsoft-first environment.

  • Build and configure Microsoft 365 workloads including Exchange Online, SharePoint, Teams, One Drive, and Microsoft Intune, supporting both new deployments and ongoing configuration changes as Trusted Tech’s environment evolves.
  • Configure and maintain on-premises infrastructure components including Windows Server environments, Active Directory Domain Services, Group Policy objects, DNS, and DHCP services in line with established standards.
  • Support the setup, configuration, and maintenance of Azure resources including virtual machines, virtual networks, storage accounts, and associated services that underpin Trusted Tech’s internal operations.
  • Participate in the implementation of hybrid identity configurations, including Entra Connect (AAD Connect) synchronization, ensuring consistent identity management across cloud and on-premises environments.
Systems Operations & Maintenance:
  • Own day-to-day operational health across assigned internal systems, proactively monitoring performance, availability, and security posture and addressing issues before they impact the business.
  • Perform routine systems maintenance including patch management, software updates, certificate renewals, and configuration hygiene across cloud and on-premises environments.
  • Manage endpoint compliance and device management through Microsoft Intune, including device enrollment, compliance policy enforcement, application deployment, and configuration profile management.
  • Maintain user identity and access management across Microsoft Entra , including provisioning and deprovisioning workflows, group and role management, and ongoing access reviews.
  • Support backup and disaster recovery operations, ensuring backup jobs run successfully, recovery procedures are tested, and any failures are identified and remediated promptly.
Automation & Process Improvement:
  • Develop and maintain Power Shell scripts and automation workflows to reduce manual effort across routine systems administration, provisioning, monitoring, and reporting tasks.
  • Identify repetitive or error-prone manual processes within the IT team’s operational workflows and proactively build automation or tooling to address them, surfacing improvements to the Director, IT and Sr. Infrastructure Architect.
  • Contribute to the development and upkeep of internal runbooks, standard operating procedures, and system documentation, ensuring the team’s institutional knowledge is captured, current, and accessible.
  • Support the evaluation and implementation of new tools or process improvements recommended by the Sr. Infrastructure Architect or Director, IT, contributing hands‑on technical execution to approved initiatives.
