Senior/IT Operations Engineer - HR Systems (Infrastructure & Systems)

The Job: You will support and maintain the HR Systems platform from an infrastructure and operations perspective. This is NOT an SAP HR Functional / SuccessFactors Config role. You will not be configuring payroll or HR workflows. You will be the technical owner who keeps the HR system secure, available, and compliant. The Role: • Manage and maintain mission-critical Windows Server and Red Hat Enterprise Linux (RHEL) servers supporting HR Systems in on-premise / hybrid environments, ensuring high availability and security compliance. • Deploy monthly WSUS updates and patch COTS / open-source software to address security vulnerabilities and maintain operational readiness. • Lead server OS upgrade initiatives to improve infrastructure stability and extend system lifecycle. • Troubleshoot and resolve server, database, and network-related issues using SQL and networking fundamentals. • Develop PowerShell and Python automation scripts to reduce manual operational workload and improve deployment efficiency. • Monitor system health, manage system logs, and coordinate with HR system vendors / SAP support teams for incident resolution. • Support user access reviews, audit evidence collection, and compliance reporting for HR Systems. • Collaborate with cross-functional teams, HR stakeholders, and IT security to support customer requirements and optimise system performance. • Maintain system documentation, runbooks, and SOPs for HR Systems operations. The Requirements: • Degree in Engineering, Computer Science, IT, or related field. • 2-4 years experience as Systems Engineer / Infrastructure Engineer / IT Ops Engineer. • Came from a mission-critical infrastructure background - not from SAP HR. • Strong hands-on experience in Windows Server and Linux (RHEL) administration. • Experience in system patching (WSUS), security vulnerability remediation, and server hardening. • Working knowledge of SQL for troubleshooting and data checks. • Good understanding of server, database, and network troubleshooting. • Ability to work in a high-compliance environment handling sensitive data. • Able to secure security clearance (required due to project sensitivity). Good to Have: • Experience with Cloud Platforms: AWS / Azure. • Experience supporting enterprise applications / HR Systems / SAP from an infrastructure perspective (although an advantage: functional SAP HR knowledge is NOT required - you will be trained on the HR application). • Experience with HTML / CSS for front-end enhancements / troubleshooting. • Hands-on scripting in PowerShell and Python for automation. • Experience in mission-critical, defence, government, or GLC environments.
