Full Job Description

Senior Network Engineer
Location: Irvine, California | Onsite | Full-Time


Help modernize the technology that keeps our people connected and our operations running.


Mitsubishi Chemical Group is seeking a Senior Network Engineer to join our Digital team, supporting our MCCFC operations in Irvine, California. This opportunity combines ownership of network infrastructure with hands-on technical support in a manufacturing environment.


You will help improve network reliability, lead infrastructure upgrades, and support employees with their everyday technology needs. You will also contribute to projects including a transition away from Citrix, network switch replacements, and technology deployment for new facilities.


If you enjoy taking a project from planning through implementation—and are equally comfortable troubleshooting a server or repairing a laptop—this role offers variety, visibility, and the opportunity to make a direct impact.


What you’ll do

  • Maintain and improve network infrastructure, including routers, switches, firewalls, cabling, and servers.
  • Lead infrastructure projects, equipment upgrades, and technology deployments, coordinating implementation to minimize disruption to operations.
  • Support the transition from Citrix to PC-based applications, including workstation deployment, application configuration, and retirement of legacy servers.
  • Coordinate network connectivity, equipment installation, and PC deployment for facility expansion projects.
  • Manage backups, file recovery, and system restoration to support business continuity.
  • Provide Level 1 and Level 2 onsite technical support, including troubleshooting and component replacement for desktops and laptops.
  • Support employees using Microsoft technologies and Microsoft 365 in a corporate environment.
  • Troubleshoot complex infrastructure issues, monitor performance, and implement improvements to reliability and security.
  • Maintain network documentation, configurations, and topology maps.
  • Use basic scripting and automation to improve recurring tasks while developing your skills alongside experienced colleagues.

What you’ll bring

  • Bachelor’s degree in computer science, engineering, or a related field highly preferred; equivalent relevant experience will be considered.
  • 7+ years of experience in network administration or engineering, including experience performing senior-level responsibilities.
  • At least two to three years of practical, hands-on experience working with network infrastructure, including switches, routers, and servers.
  • Experience troubleshooting and repairing desktop and laptop hardware, including replacing individual components.
  • Working knowledge of Microsoft technologies and Microsoft 365 administration and support in a corporate environment.
  • An understanding of network architecture, protocols, and security practices.
  • Experience coordinating infrastructure upgrades, migrations, or other technology projects.
  • Basic scripting skills, such as PowerShell or Python, and an interest in expanding your automation capabilities.
  • Strong troubleshooting, communication, and organizational skills, with the ability to manage competing priorities and work independently.
  • Manufacturing experience is preferred. Professional certifications are not required.
  • Site-specific on-call and after-hours support is required
