RDL Network Administrator in Toronto

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.

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, this role requires a hands-on, highly disciplined administrator who excels at executing manual and semi-automated workflows securely and consistently.

• Identity & Secure Access Administration
  • User Onboarding & Management: Provision local user accounts and role-based permissions.
  • Remote Session Administration: Administer daily customer connections and internal user access.
  • Security Audits: Review, audit, and clean up inactive user sessions and local accounts weekly.
• Data Transfer & Repository Sync Operations
  • Multi-Tier Sync Execution: Execute and monitor the secure transfer of data packages.
  • Local Repo Hosting: Ensure local web repositories are operational and accessible.
  • Integrity Validation: Verify the cryptographic hashes of all data packages.
• Support Ticket Resolution & SLA Adherence
  • End-User Support: Act as the primary technical point of contact for network troubleshooting.
  • Ticketing Operations: Process, update, and resolve secure lab support tickets.
  • Escalation Point: Identify complex network issues and elevate them to the Lead Network Architect.
• Compliance & Clean Environment Enforcement
  • Software Auditing: Conduct regular logical audits of systems within the RDL.
  • Asset Tracking: Maintain a flawless inventory of all HPS-owned assets inside the RDL.

• Air-Gap Protocols: Working knowledge of secure file transfer protocols.

Preferred Certifications
