Sr. Network Engineer
About The Position
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.

- At least two to three years of practical, hands-on experience working with network infrastructure, including switches, routers, and servers.

- 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.
- Site-specific on-call and after-hours support is required.

- Bachelor’s degree in computer science, engineering, or a related field highly preferred; equivalent relevant experience will be considered.

- Professional certifications are not required.
Responsibilities
- 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.
