Research & Development Labs Network Admin

Celestica International LP • Richardson, TX

2d • Onsite

About The Position

We are seeking a proactive and detail-oriented RDL Network Administrator to manage the day-to-day operations and administration of our global Research and Development Lab (RDL) networks. Reporting directly to the Lead Network Architect, you will be responsible for the run-and-maintain aspects of our isolated, air-gapped networks across multiple HPS Design Center locations (including San Jose, Richardson, Thailand, Shanghai, SongShan Lake, Penang, Chennai, and future sites).

The ideal candidate will handle routing, switching, and firewall adjustments, manage user access, configure local jump hosts, and execute secure file transfers across air gaps. Since this environment operates under strict security isolation without typical enterprise automated management tools (e.g., Active Directory, automated endpoint agents), this role requires a hands-on, highly disciplined administrator who excels at executing manual and semi-automated workflows securely and consistently.

Requirements

• Practical experience configuring and troubleshooting Cisco switches (Catalyst/Nexus) and administering Checkpoint Firewalls (defining security rules, NAT, and logs).
• Mid-to-senior level competency in Linux (Rocky, CentOS, Ubuntu)—specifically user management, bash scripting, basic routing, and running local web servers (Apache/Nginx).
• Experience working with remote access tools such as Zscaler ZTNA / App Connectors and Privilege Access Management solutions (specifically CyberArk).
• Solid experience administering VMs, clusters, and virtual switches within VMware vSphere or Microsoft Hyper-V environments.
• Working knowledge of secure file transfer protocols (SFTP, SCP, rsync) and security scanning methodologies.
• Bachelor’s degree in Network Administration, Information Technology, Computer Science, or equivalent hands-on experience.
• 4+ years of experience in network administration or system administration, preferably managing secure, segmented, or laboratory networks.

Nice To Haves

• CCNA (Cisco Certified Network Associate)
• Check Point Certified Security Administrator (CCSA)
• CompTIA Security+ or Linux+
• CyberArk Certified Trustee or Defender
• High Operational Discipline: Ability to strictly adhere to Standard Operating Procedures (SOPs) without cutting corners, even during urgent troubleshooting.
• Excellent Communicator: Strong written and verbal communication skills, necessary for translating technical issues to designers and coordinating with corporate security teams.
• Multi-Tasker: Capable of balancing ticket requests from multiple global labs concurrently while maintaining accurate records.

• Daily Network Operations & Maintenance: Infrastructure Monitoring, Configuration Management, Routine Maintenance.
• Identity & Secure Access Administration: User Onboarding & Management, Remote Session Administration, Security Audits.
