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).
This role uniquely focuses on cutting-edge open networking. The majority of our RDL network infrastructure runs on SONiC (Software for Open Networking in the Cloud) deployed on Celestica’s own high-performance network switches. Furthermore, security inside the air-gap relies heavily on Zscaler technology acting as internal firewalls integrated with local VLANs for precise, policy-driven access control.
Since this environment operates under strict security isolation without typical enterprise automated management tools, this role requires a hands-on, highly disciplined administrator who excels at executing manual and semi-automated workflows securely and consistently. Traditional Cisco-based networking skills are considered secondary to expertise in SONiC, Linux networking, and Zscaler-driven zero-trust security.
This role requires regular on-site presence within the RDL environment and participation in a 24x7 on-call rotation supporting global RDL infrastructure, including after-hours incident response and scheduled maintenance activities.
