Brussel

Solliciteer

The System Engineer provides advanced operational support for Linux-based IT infrastructure, with a strong focus on system monitoring, observability, and reliability. They ensure platform stability, performance, and availability through proactive monitoring, alerting, and continuous analysis of system health.

The engineer is responsible for timely resolution of incidents and service requests, leveraging monitoring data and diagnostics to identify and address OS-level issues. They perform routine maintenance and implement system changes in line with established processes and standards, ensuring minimal service disruption.

A key aspect of the role is the design, implementation, and continuous improvement of monitoring solutions, including metrics collection, logging, alerting, and dashboards. The engineer uses these capabilities to detect anomalies early and improve overall service quality.

The engineer contributes to problem management by performing root cause analysis based on monitoring data, logs, and system behavior, and by proposing and implementing long-term corrective actions. They collaborate with cross-functional teams to ensure systems are secure, compliant, and effectively monitored end-to-end.

In addition to operational duties, the engineer participates in R&D activities, evaluating new technologies and observability tooling, and contributing to solution prototypes. They drive automation through scripting and Infrastructure-as-Code to enhance monitoring coverage, reduce manual intervention, and increase platform reliability.
