Because this individual is HMC’s primary on-site IT resource, success requires initiative, consistent follow-through, strong troubleshooting skills, and the ability to work independently. The ideal candidate anticipates needs, addresses problems proactively, and takes ownership of issues through resolution. SRM’s centralized engineering and information security teams provide specialized expertise, infrastructure design, and assistance with complex technical issues.

Travel to the SRM Home Office is required at least quarterly, with a minimum of four trips annually, including attendance at the annual leadership conference. Additional local or overnight travel may be required for projects, support, or acquisition activities.

The position participates in after-hours on-call support and occasional Saturday or scheduled weekend maintenance. Support coverage and handoffs will be coordinated with the broader SRM IT department.

Physical Requirements

Ability to move and install typical computer hardware and peripherals, place equipment on desks, and mount monitors, with reasonable accommodation. Work in manufacturing

areas requires compliance with applicable safety procedures and personal protective equipment requirements.

Professional Development

On-the-job training and collaboration with SRM’s engineering and security teams provide opportunities to expand technical skills and contribute to broader IT initiatives.

Your Mission & Key Responsibilities

• Provide responsive daily support for HMC’s office and manufacturing operations, prioritizing issues that affect production and employee productivity.
• Install, configure, maintain, and troubleshoot computers, printers, monitors, mobile devices, peripherals, operating systems, and business software.
• Support employee onboarding, role changes, and offboarding through equipment provisioning, account administration, group assignments, and access changes.
• Administer assigned Active Directory, Microsoft Entra ID, Group Policy, DNS, and DHCP functions using established procedures.
• Troubleshoot wired and wireless connectivity, VPN access, IP addressing, and local network equipment.
• Perform routine server, workstation, and infrastructure administration, including monitoring, patching, updates, and preventive maintenance.
• Monitor backup status, address failures, and assist with recovery and testing in coordination with SRM’s systems engineering team.
• Support business applications and coordinate with vendors and internal specialists when additional expertise is required.
• Use approved tools to manage workstations, servers, peripherals, and networks locally and remotely.
• Follow company security standards for endpoint protection, authentication, permissions, and system configuration; promptly elevate security concerns.
• Maintain accurate support records, equipment inventories, configurations, and operating procedures.
• Identify recurring issues and recommend practical improvements.
• Coordinate with SRM’s engineering teams on infrastructure changes, complex incidents, equipment replacements, and projects; provide local implementation assistance.
• Extend support to other SRM employees, locations, and systems as assigned while maintaining dependable HMC coverage.
• Participate in the IT on-call rotation, occasional Saturday support, and scheduled weekend maintenance.
