Key Responsibilities
Patch Planning and Deployment
- Plan, schedule and execute monthly and out-of-band patch cycles for Linux servers across all managed client estates, covering kernel, security and package updates.
- Build ring-based deployment approaches that move updates from pilot groups to production in a controlled sequence, with defined pause and rollback criteria.
- Coordinate maintenance windows and reboot schedules with clients and application owners, and confirm service health before and after each cycle.
- Respond to critical vulnerability advisories with emergency patch cycles, working with the security team to prioritise by risk and exposure.
- Apply live patching and reboot-minimising approaches where the distribution and client policy support them.
Platform and Repository Administration
- Administer Azure Update Manager for Linux, including maintenance configurations, dynamic scopes, assessment schedules and periodic assessment for Azure and Arc-enabled servers.
- Manage package updates across the supported distributions using yum, dnf, apt and zypper, including package pinning, exclusions and dependency resolution.
- Maintain internal repositories and mirrors, and manage subscription and content channels through tooling such as Red Hat Satellite, SUSE Manager, Landscape or a local mirror.
- Keep update agents, Arc connectivity and reporting healthy across the estate, and remediate machines that stop reporting assessment data.
- Manage configuration drift and enforce baseline package state using automation tooling such as Ansible.
Compliance, Troubleshooting and Reporting
- Track patch compliance against agreed targets, investigate failed and pending updates, and remediate systematically rather than server by server.
- Troubleshoot update failures from package manager logs, systemd journals and update agent logs, and resolve recurring causes at source.
- Handle post-patch issues including failed services, kernel module and driver mismatches, and roll back where a change proves unsafe.
- Produce monthly patch compliance reporting for service delivery managers and client stakeholders, with clear commentary on exceptions and planned remediation.
- Conduct root cause analysis on recurring patch failures and drive permanent fixes through the problem management process.
Service Delivery, Automation and Documentation
- Raise, own and close change records for every patch cycle, with tested implementation and rollback plans.
- Handle incidents and service requests within agreed SLA targets, keeping ticket records accurate and current.
- Automate patching workflows, reporting and routine health checks using Bash, Python and Ansible, and contribute reusable playbooks to the team's automation library.
- Maintain runbooks and as-built documentation so that the service desk can act confidently on first contact, and mentor junior engineers on Linux patching practice.
- Participate in the on-call rotation and support out-of-hours maintenance windows, which is where the majority of patching work is delivered.
Required Qualifications
- Bachelor's degree in computer science, information technology or engineering, or equivalent practical experience.
- Four to seven years in Linux systems administration, with at least three years focused on enterprise patch and vulnerability remediation.
- Strong hands-on experience with Red Hat Enterprise Linux, CentOS or Rocky, together with Ubuntu or SUSE.
- Practical experience with yum, dnf, apt and zypper, including repository configuration, package pinning and dependency troubleshooting.
- Hands-on experience patching Linux through Azure Update Manager, or a comparable centralised patch platform.
- Confident troubleshooting of kernel updates, reboot handling, service recovery and post-patch failures.
- Working scripting ability in Bash or Python, and practical experience with Ansible for bulk remediation.
- Experience working to formal ITIL processes for incident, problem and change management within a ticketing platform such as Jira Service Management or ServiceNow.
- Willingness to work rotational shifts and scheduled maintenance windows, including nights and weekends, as part of a 24x7 support roster.
- Clear written and spoken English, with confidence in client-facing communication.
Preferred Qualifications
- Red Hat certification such as RHCSA or RHCE, or an equivalent Linux Foundation certification.
- Microsoft certification such as AZ-104 or AZ-800, or experience with Azure Arc at scale.
- Experience with Red Hat Satellite, SUSE Manager, Landscape or Spacewalk for content and lifecycle management.
- Familiarity with vulnerability management tooling such as Microsoft Defender Vulnerability Management, Qualys or Tenable, and with mapping findings to patch cycles.
- Experience with live kernel patching technologies such as kpatch, ksplice or livepatch.
- Exposure to Windows patching tooling, since the wider team also runs SCCM, WSUS and Patch My PC.
- Experience supporting multiple customer environments for a managed services or outsourcing provider, and ITIL 4 Foundation certification.
