Your Moneris Career – The Opportunity

As a Systems Administrator III (Linux), you will engineer, automate, secure, and continuously improve the enterprise Red Hat Enterprise Linux (RHEL) platform that underpins Moneris’ business-critical payments services across on-premises data centers and cloud.

This is a senior, hands-on infrastructure role centered on operating and modernizing a large-scale RHEL estate of thousands of virtual machines spanning development through mission-critical production. You will build reusable automation at scale with Ansible, Python, and Bash; drive lifecycle management through patching, upgrades, and migrations; and harden the environment against payments-industry compliance standards. Working independently with sound judgment, you will partner with Platform, Site Reliability Engineering (SRE), Cloud Operations, Information Security, and Infrastructure Architecture teams to deliver a consistent, resilient, and secure operating environment. You will also mature service ownership, mentor less-experienced colleagues, and reduce operational drift through standards-based engineering.

Location: You will be based in our Toronto office, balancing in-office collaboration with remote flexibility.

Reporting Relationship : You will report to Manager, Systems Infrastructure

Posting Type: Replacement Position

Salary Range: The expected base salary range for this role is $85,000 - $113,000

Total compensation may also include variable or discretionary incentive components, including but not limited to bonuses and commissions. Individual job offers are determined by various factors , including experience, education, skills, certifications, and other business needs.

Your Moneris Career – What you'll do

Administer, maintain, and support a large-scale RHEL estate of thousands of virtual machines across development, test, and mission-critical production.

Build and maintain reusable automation at scale using Red Hat Ansible, Bash, Python, and GitHub to enforce standards and reduce manual effort.

Manage platform currency through patching, upgrades, in-place migrations, remediation, and decommissioning using Red Hat Satellite and Hybrid Cloud Console.

Lead and support projects covering implementation, modernization, service transition, and operational readiness across hybrid infrastructure.

Troubleshoot complex issues to root cause across operating system, compute , storage, virtualization, identity, and network-adjacent layers.

Support server hardening, vulnerability remediation, and compliance activities within a least-privilege, PCI DSS-regulated environment.

Manage incidents, requests, problems, and changes in ServiceNow, aligned to enterprise ITIL change management processes.

Create and maintain build standards, automation playbooks, technical documentation, diagrams, and knowledge base articles.

Your Moneris Career – What you bring

Required qualifications

Minimum 3 years administering and supporting Red Hat Enterprise Linux 7/8/9/10 on x86_64 at enterprise scale, including thousands of VMs across multiple environments.

Extensive hands-on automation experience with Red Hat Ansible, Bash, Python, and GitHub to deliver standards-based, consistent, secure environments at scale.

Strong experience with Linux build, patching, upgrade, in-place migration, and decommissioning workflows, including Red Hat Satellite and Hybrid Cloud Console.

Experience integrating RHEL with Active Directory using SSSD and Kerberos keytabs within a least-privilege security model.

Experience with virtualization such as VMware vSphere or Nutanix AHV and supporting Infrastructure as a Service (IaaS) virtual machines in Microsoft Azure.

Demonstrated root-cause troubleshooting across OS, compute , storage, virtualization, and network-adjacent layers, with a record of continuous service improvement.

Working knowledge of IPv4 fundamentals, network segmentation, PKI, backup, recovery, and disaster recovery concepts, plus ServiceNow and ITIL processes.

Preferred qualifications

Experience in a regulated industry, ideally payments or Payment Card Industry Data Security Standard (PCI DSS) environments.

Familiarity with server hardening using Center for Internet Security (CIS) benchmarks and National Institute of Standards and Technology (NIST) guidelines, with tools such as Microsoft Defender, OpenSCAP , and Forta Tripwire.

Experience with CyberArk Privileged Access Management and Conjur secrets management , Venafi, Azure Arc, and Microsoft Defender for Endpoint (ATP).

Exposure to container-based infrastructure, DevOps pipelines, and observability tooling such as CheckMK and Dynatrace, plus GlusterFS /FUSE, NFS, and Postfix.
