Network Operations Engineer

As a Senior Network Operations Engineer, you will join an Agile networking squad responsible for the day-to-day operation and continuous improvement of a large-scale enterprise office network. You’ll work with modern HPE Aruba, wired, wireless, SD-WAN and network access technologies to provide reliable and secure connectivity across offices worldwide.

Important: For this position, we can only consider candidates who have previous professional working experience within the EU. Applications from candidates without EU work experience will unfortunately not be considered.

• Perform structured root cause analysis (RCA) and help prevent recurring network issues.
• Independently handle operational tickets, service requests, configuration changes and deployments.
• Monitor network services, interpret alerts and assess their potential impact on users and business services.
• Troubleshoot enterprise authentication and network access flows, including 802.1X and RADIUS.
• Work with SD-WAN technologies, including overlays, IPsec connectivity, segmentation and routing.
• Work hands-on with HPE Aruba networking technologies within a large-scale enterprise environment.
• Improve operational efficiency through Python scripting, REST APIs, automation, monitoring and documentation.
• Test and support network releases and configuration changes before and after deployment.
• Collaborate with regional IT teams, suppliers, stakeholders and end-users to resolve operational issues.
• Participate actively in Agile/Scrum ceremonies and contribute to the continuous improvement of the team.
• Participate in an occasional standby/on-call rotation.
