Systems Administrator Jobs

Systems administration might sound old-school in the age of cloud-native everything, but with 69 active roles it remains a critical function — particularly as companies manage hybrid cloud environments and enterprise SaaS platforms. Dublin dominates with 47 positions, with Limerick (8) and Cork (5) adding regional depth.

Salesforce leads with 7 positions at Salesforce Tower in North Dock, hiring systems administrators for its internal IT operations and customer-facing platform engineering. Revolut has 6 roles spanning infrastructure management for its fintech platform serving 70+ million customers. Amazon recruits 5 systems professionals for its Dublin data centre operations. Analog Devices at Raheen Business Park, Limerick hires 4 systems administrators for its semiconductor manufacturing IT infrastructure.

The cybersecurity and middleware sector adds specialist demand. Axway has 4 positions for API management and integration platform administration. PFH Technology recruits 3 systems professionals for managed IT service delivery. EY and Grant Thornton hire systems administrators to support their consulting and advisory practices.

At the scale-up end, Intercom and Meta each contribute positions, while Salesforce roles often blur the boundary between traditional systems administration and CRM platform engineering — reflecting how the role has evolved from on-premises server management to cloud platform governance.

What skills are in demand? The core stack includes Linux and Windows Server administration, Active Directory, VMware/Hyper-V virtualisation, and cloud platforms (AWS, Azure, GCP). For Salesforce-platform roles, Salesforce Admin certification and Apex/Flow development skills are increasingly expected. Network administration skills including DNS, DHCP, firewall management, and VPN configuration remain valued. The career path runs from Systems Administrator and IT Support Engineer through Senior Systems Administrator to Infrastructure Manager and IT Director — with the more technical track branching into cloud engineering and DevOps, which are covered as separate career paths on HiringNow.ie.

The evolution of systems administration reflects the broader shift in IT infrastructure. A decade ago, the role centred on managing physical servers in on-premises data centres. Today, it spans hybrid cloud environments, identity and access management (Azure AD, Okta), endpoint management (Jamf, Intune), and SaaS platform governance � managing the configuration, security, and integration of dozens of cloud applications that form the modern enterprise technology stack. For systems administrators who embrace this evolution, the career remains robust and offers strong compensation, with the added benefit of skills that are directly transferable to cloud engineering and DevOps roles.
