RDL Jump Host Admin in Toronto

We are seeking an experienced, compliance-driven RDL Jump Host Administrator to take ownership of the system administration, security, and access control of our global local jump hosts.

Reporting directly to the Lead Network Architect, and working in close alignment with the RDL Network Administrator, you will manage secure access pathways into completely isolated, air-gapped lab networks across multiple HPS Design Centers (including San Jose, Richardson, Thailand, Shanghai, Song Shan Lake, Penang, Chennai, and future sites).

The primary objective of this role is to ensure that remote connections terminating from corporate Zscaler ZTNA or customer Cyber Ark v PAM environments are securely processed, authenticated, and audited.

Since our environments strictly prohibit Active Directory or domain joins, you will manage decentralized, local authentication configurations, shell environments, and session boundaries.

Crucially, you will implement and maintain the strict compliance frameworks required for Export Controlled VLANs—including interactive terms-of-use banners, mandatory user acceptance gates for shell access, and tamper-proof user-acceptance audit logging.

• Core Responsibilities
• Server Provisioning & Lifecycle: Deploy, configure, and maintain Linux-based (Rocky Linux, Ubuntu, Cent OS) local jump host virtual machines operating on VMware v Sphere or Microsoft Hyper-V clusters.
• Operating
• System

Hardening: Apply strict CIS (Center for Internet Security) hardening benchmarks on all jump host operating systems.

Ensure that no unauthorized software or corporate agents (e. g., Crowd Strike, Service Now, Clear Pass, Windows Domain utilities) are installed or active on endpoints installed on the VLAN behind the Jump Host.

• Service Availability: Ensure the high availability, performance, patch status, and storage capacity of jump servers acting as gateways to the core RDL networks.
• 2. Export Control Compliance & Interactive Gates
• Export
• Control
• Shell

Banners: Configure and manage interactive, mandatory user agreement screens (e. g., using custom shell login scripts, Pluggable Authentication Modules (PAM), or SSH Force Command) specifically for systems accessing Export Controlled VLANs.

• User
• Acceptance

Verification: Ensure that users cannot acquire an interactive shell, run commands, or bypass the landing screen without explicitly reading and accepting the export control and NDA terms.

• Tamper-Proof Acceptance Logging: Implement and maintain robust, structured logging systems (using Rsyslog, Journald, or custom secure local logging scripts) that capture:
• The authenticated user's local/remote identifier.
• Source IP and connection timestamp.
• Explicit timestamped confirmation of the user's compliance acceptance.
• Log Archival & Integrity: Set up secure, write-only log forwarding or local hashing protocols to ensure audit logs of export-control acceptances cannot be modified or deleted by general users.
• 3. Identity, Access, & Session Management
• Decentralized Local Authentication: Programmatically or manually provision local Unix user accounts, localized Role-Based Access Control (RBAC), and SSH keys on all jump hosts.
• Remote
• Integration

Support: Partner with corporate IT to ensure seamless hand-offs from Zscaler ZTNA (via local Zscaler App Connectors) and Cyber Ark v PAM sessions terminating on the jump hosts.

• Session Controls: Configure strict SSH timeouts, idle session terminations, and multi-factor authentication loops to prevent abandoned active connections.
• 4. Operations, Ticket Resolution & Collaboration
• Workplace

Collaboration: Align daily with the RDL Network Administrator to coordinate VLAN mappings, firewall rule adjustments, and routing protocols necessary for jump host access.

• Engineering Support: Serve as a technical point of contact for HPS design engineers having credentialing, shell, or connection issues when entering secure environments.
• Incident & Audit

Readiness: Assist the Lead Network Architect in pulling audit trails and access reports during compliance reviews, system security audits, or customer security evaluations.

• Required Technical Skills
• Linux Expertise (Expert Level): Mastery of Linux OS administration (Rocky Linux, RHEL, Cent OS, Ubuntu) including shell scripting (Bash, Python), security policies, and package management.
• Secure Access & Authentication: Comprehensive knowledge of SSH daemon configuration (sshd_config), PAM (Pluggable Authentication Modules) stack configuration, and secure local authentication patterns.
• Audit & Log Engineering: Proven experience configuring structured logging systems, syslog routing, Rsyslog, or Journald to create secure, immutable compliance audit trails.
• Access Technologies: Familiarity with Zscaler ZTNA (App Connectors), Cyber Ark v PAM, and Virtual Private Network (VPN) architectures.
• Virtualization Basics: Practical experience administering virtual machines, virtual switches, and storage within VMware ESXi / v Center or Microsoft Hyper-V.
• Preferred Certifications
• Red Hat Certified System Administrator (RHCSA) or Engineer (RHCE)
• Comp TIA Security+ or GISF (GIAC Information Security Fundamentals)
• Cyber Ark Certified Sentry or Trustee
• Soft Skills & Working Style
• Extreme Attention to Detail: Precise, systematic approach to system configuration, security rules, and audit trail maintenance.
• High Integrity: Uncompromising commitment to maintaining security barriers, compliance standards, and ethical handling of export-controlled hardware and software.
• Excellent

Communicator: Strong written and verbal communication skills, necessary for writing technical LLD/SOP documentation, explaining access gates to end-users, and coordinating with the RDL Network Architect.

• Physical Demands
• Duties of this position are performed in a normal office environment.
• Duties may require extended periods of sitting and sustained visual concentration on a computer monitor or on numbers and other detailed data.

Repetitive manual movements (e. g., data entry, using a computer mouse, using a calculator, etc.) are frequently required.
