Senior Atlassian System AdminActive€40K–€60K

The opportunity

For Portugal based hires: Estimated annual salary is between €40,000 - €60,000.

What you'll do

  • System Maintenance & Security: Lead the end-to-end patching process for Jira Data Center/Server instances. Monitor Atlassian Security Advisories and perform version upgrades to ensure the environment is secure and performant.

  • Instance Governance: Serve as the primary gatekeeper for the Jira configuration. Manage global settings, including workflows, permission schemes, screen schemes, and custom field consolidation.

  • Automation & Customization: Develop and maintain complex scripts using ScriptRunner (Groovy) to automate business logic, extend Jira’s native capabilities, and integrate with external APIs.

  • Performance Monitoring: Conduct regular health checks, JVM tuning, and re-indexing. Troubleshoot system-level issues (logs, database connectivity, or plugin conflicts) to minimize downtime.

  • User Support & Training: Provide "Tier 3" support for internal teams, helping them translate business requirements into efficient Jira projects without creating "configuration bloat."

  • Atlassian Expertise: 7+ years of experience as a Jira Systems Administrator, with specific experience both in On-Prem (Data Center or Server) environments AND cloud migration experience.

What they're looking for

  • Scripting Proficiency: Advanced knowledge of Groovy and the ScriptRunner plugin. You should be comfortable writing scripts that interact with the Jira API.
  • Infrastructure Knowledge: Strong understanding of the underlying tech stack: Linux/Windows servers, SQL databases (PostgreSQL/SQL Server), and SSL/Certificate management.
  • Technical Troubleshooting: Ability to analyze log files (atlassian-jira.log) and thread dumps to identify the root cause of system instability.
  • Change Management: Experience operating in a production environment where "uptime is king," following strict change-control processes for all patches and updates.
