Experienced application support engineers move into DevOps Engineer, Site Reliability Engineer (SRE), Platform Engineer, or Application Support Manager roles.
Application Support Engineers in Ireland earn €52,000 to €90,000 depending on experience and technical depth. Senior engineers with strong SQL skills, Linux administration experience, and expertise in monitoring tools like Splunk or Dynatrace earn toward the upper end. Financial services organisations and large tech multinationals in Dublin typically pay above the market median.
Application Support Engineers focus on maintaining existing application functionality, resolving incidents, and managing releases. SREs take a more proactive and engineering-focused approach, building automated systems to prevent incidents, improve reliability, and reduce operational toil. SRE roles typically command €15,000 to €25,000 more in Ireland and require stronger software development skills alongside operational expertise.
Progression typically requires ownership of L3 incidents, the ability to independently investigate root causes across the full application stack (application logs, database queries, infrastructure metrics), and a track record of improving system reliability through process improvements or automation. ITIL 4 certification and tool expertise in Splunk, Dynatrace, or ServiceNow are common requirements for senior roles.
Yes, and it is a well-trodden path. Engineers who are proficient in SQL and scripting languages (Python, Bash, PowerShell) and who have a deep understanding of how production applications behave are well positioned for junior-to-mid software engineering roles. Some organisations have formal pathways for support engineers to move into development roles internally.
