Sr. IT Services Engineer / Systems Administrator

At Senra Systems, we believe that the future of manufacturing lies not in automation, but in configuration.  

We supercharge electrical wire harness manufacturing through software configuration, transforming skilled assembly tasks into high-throughput production lines. We enable customers to design what they want, when they want it and deliver harness builds at record-breaking speed.

What You'll Do

• Manage day-to-day IT operations across our Redondo Beach and Cypress facilities, including hardware, software, networking, identity, endpoints, and user lifecycle management.
• Administer and maintain Microsoft 365, Entra ID, Intune, Windows/macOS endpoints, servers, cloud infrastructure, and core business applications.
• Support production-floor technology and troubleshoot systems that directly impact manufacturing operations, minimizing downtime and escalating issues appropriately.
• Own and maintain the corporate and production printing environment, including standard office printers and specialized label/production printing systems such as Zebra, Brady, and Brother, including connectivity, drivers, print services, configuration, and troubleshooting.
• Manage and support conference room and audiovisual technology, including Microsoft Teams Rooms, displays, cameras, microphones, room resource accounts, and related meeting-room equipment.

• Provision, configure, deploy, and maintain laptops, desktops, tablets, mobile devices, kiosks, and shared/production workstations.
• Set up and support new hires with appropriate equipment, Microsoft 365 licensing, security controls, application access, and access to internal manufacturing systems.
• Administer identity and access controls, including account provisioning/deprovisioning, MFA, groups, permissions, service accounts, and shared/resource accounts.
• Monitor system, network, and endpoint health and proactively identify issues before they impact office or manufacturing operations.
• Maintain endpoint security, patching, backups, disaster recovery, and system configuration standards.
• Support IT and cybersecurity compliance requirements, including CMMC and NIST SP 800-171, through implementation, documentation, evidence collection, access controls, configuration management, and remediation activities.
• Maintain accurate documentation of infrastructure, configurations, assets, procedures, troubleshooting steps, and IT policies.
