DevOps & Site Reliability Engineer Jobs

DevOps, SRE, and platform engineering have matured into one of Ireland's most in-demand technical career paths, with 156 active roles concentrated in Dublin (103) but with meaningful clusters in Cork (19), Galway, and Limerick. The common thread across these roles is automation — building, deploying, and maintaining the infrastructure that keeps software running at scale.

Mastercard at South Bank House on Barrow Street leads hiring with 14 positions, including Director of Site Reliability Engineering — a senior leadership role responsible for ensuring the reliability of payment systems that serve 200+ countries. The SRE function at Mastercard focuses on making transactions safe, simple, and accessible through secure data and trusted networks. Canonical, the company behind Ubuntu, hires remotely for Site Reliability and GitOps Engineers — "automation-first" technologists with a passion for Linux who join a globally distributed team of 1,200+ colleagues in 75+ countries.

The financial and trading sector adds high-performance infrastructure demand. SIG (Susquehanna) at 2 Grand Canal Square recruits DevOps Engineers to design and deliver market-leading technology products, with responsibilities spanning multi-region infrastructure deployment, CD pipelines, and monitoring solutions using Grafana, GrayLog, and Prometheus. The emphasis is on scalability and reliability as key design requirements — critical when milliseconds affect trading outcomes.

Pharma automation represents a distinct flavour of this career path. SIMO Technology has 6 positions including OEM Automation Engineers supporting pharmaceutical clients on major site expansion projects in Dublin. These roles require deep experience in Rockwell Automation platforms and formulation process control — a reminder that DevOps principles extend well beyond web applications into manufacturing execution systems.

Personio and DoiT International bring the startup and scale-up dimension, while Apple and Cisco add enterprise tech depth. Zinkworks in Galway recruits for DevOps roles focused on telecom infrastructure automation.

What skills are employers looking for? The core stack includes Kubernetes, Docker, Terraform, CI/CD pipeline design (Jenkins, GitHub Actions, ArgoCD), and deep Linux expertise. Cloud platform certification in AWS, GCP, or Azure is increasingly expected rather than preferred. For SRE-specific roles, experience with incident management, SLO/SLI frameworks, and observability tooling is essential. The career ladder runs from DevOps Engineer and Test Automation Engineer through Senior Platform Engineer and DevSecOps Engineer to DevOps Manager and Director of SRE — with the senior end offering compensation that competes directly with staff-level software engineering roles.
