Everybody uses Jira. Almost nobody runs it properly at this scale, under these security rules.

You would be the senior engineer behind the collaboration platform of a multinational defence security centre in Mons, Belgium — administering the Atlassian estate, integrating it with everything around it, and keeping it secure.

What you would be doing

• Deploying, installing and configuring Jira Software Data Center, Confluence Data Center and the plugins around them, to best practice and to the customer's own security direction
• Adding the plugins, add-ons and integrations the business actually needs
• Guarding the confidentiality and integrity of what sits in there
• Proactive maintenance and administration — users, access control, permissions — through the service management tool
• Raising, chasing and implementing change requests: new releases, security patches, user features ready for production
• Dealing with vendor support for bugs and feature requests
• Monitoring performance, troubleshooting, and tuning for security, reliability and resilience
• Running backups with the backup team, and testing and reporting on disaster recovery
• Applying security patches and upgrades promptly, and auditing so that need-to-know actually holds
• Supporting users, migrating data in and out, and customising workflows, forms and dashboards to how teams really work
• Integrating with the wider estate, including the Microsoft product suite and SharePoint
• Writing the documentation, and keeping an eye on where the products are heading

What you would bring

• At least five years administering Jira Data Center or Confluence Data Center
• System administration in Linux environments
• Scripting for automation — Bash, Python
• Excellent Java, Groovy and ScriptRunner
• A strong grounding in networking and security practice
• Migrations into or out of the Atlassian stack
• Working within IT service management
• Ownership: the wish to finish what you start
• Excellent information management, and communication that makes technical detail land
• Professional English

Nice to have

• An Atlassian product certification
• A software development background, and Ansible
• Work for or with a military or governmental organisation

Why this one is worth a look

It is platform ownership, not ticket triage — the estate is yours to design, secure and automate.
