Endpoint security is where a lot of good intentions meet a lot of real machines. A multinational defence organisation in Brussels needs someone who genuinely knows the Trellix product range and can run it across a mixed Windows and Linux estate - not just install it, but keep it healthy, tuned and understood.
The role mixes engineering with service delivery: high availability matters, ITIL process matters, and so does the ability to take an alert nobody can explain and follow it to its root cause.
What you would be doing

 * Implement and manage the full range of Trellix products - threat prevention, application control, host firewall, data loss prevention, drive encryption and the rest - on Windows end user devices and on Windows and Linux servers.
 * Deliver that service in a complex IT environment, following ITIL processes and keeping availability high.
 * Analyse security events, logs, alerts and endpoint data exchange.
 * Drive root cause analysis and problem solving on issues that do not resolve themselves.
 * Document what you do and share the knowledge so the team is not dependent on one person.
 * Take ownership of technical issues and see them through., The role is based in Brussels, Belgium, on site for most daily activity with a limited possibility of one day a week remote, from early November to the end of December 2026.
