• Monitor and support global network connectivity across data centers, offices, cloud environments, and private network links.
• Troubleshoot routing, switching, firewall, and connectivity issues across first- and second-line support.
• Administer firewall configurations, including ACL changes, NAT rules, VPN checks, and related operational tasks.
• Provision and maintain VLANs, interfaces, trunks, and cross-connects on Arista or comparable network infrastructure.
• Coordinate network turn-ups, moves, additions, and changes with data center providers, clients, and internal engineering teams.
• Configure and maintain monitoring dashboards, alerts, health checks, and other network observability capabilities.
• Support planned network maintenance, firmware upgrades, patching, and infrastructure changes.
• Maintain accurate and up-to-date network, firewall, and infrastructure documentation.
• Contribute to CI/CD practices for network configuration management using Git and related tooling.
• Develop and maintain network automation and scripting using Python, Ansible, Terraform, or comparable technologies.
• Identify repetitive operational tasks and work with senior engineers to automate them.
• Collaborate with experienced network engineers to progressively take ownership of more complex engineering and infrastructure initiatives.
• Follow structured change-management and operational processes to ensure network availability, security, and reliability.

Requirements

• 2-3 years of professional experience in network engineering, network operations, NOC support, or a closely related role.
• Solid understanding of networking fundamentals, including routing, switching, VLANs, interfaces, trunks, and connectivity troubleshooting.
• Hands-on experience with at least one major networking vendor such as Cisco, Arista, Fortinet, or a comparable platform.
• Practical experience supporting or administering firewalls, including ACLs, NAT, VPNs, and basic security configuration.
• Experience working with structured change-control processes in production environments.
• Familiarity with data center networking and infrastructure.
• Exposure to scripting or network automation using Python, Ansible, Terraform, or similar tools.
• Strong troubleshooting and analytical skills, with the ability to diagnose complex connectivity and infrastructure issues methodically.
• Proactive and continuous-improvement mindset, with an interest in reducing manual operational work through automation.
• Ability to remain effective in a fast-paced, high-pressure environment where network availability has a direct impact on customers.
• Strong communication skills and the ability to collaborate effectively with senior engineers, technical teams, service providers, and external clients.
• CCNA certification or equivalent networking knowledge is advantageous.
• Experience with FreeBSD, Unix, or Linux environments is a plus.
• Familiarity with AWS, Azure, or Google Cloud networking is beneficial.
• Experience with VMware, Hyper-V, or other virtualization technologies is an advantage.
• Knowledge of Precision Time Protocol (PTP) or low-latency infrastructure is highly beneficial.
• Familiarity with ISO 27001 or other security and compliance frameworks is a plus.
• Willingness to learn, develop automation expertise, and progress toward more advanced network engineering responsibilities.

Benefits

• Fully remote position within Europe.
• Opportunity to work with global data center and network infrastructure supporting latency-sensitive financial workloads.
• Hands-on exposure to technologies including Arista, FortiGate, pfSense, BGP, VPLS/eVPN, Ansible, Terraform, Python, and Git.
• Opportunity to develop from traditional NOC operations into network automation and engineering.
• Close collaboration with experienced senior network engineers and opportunities for mentorship.
• Exposure to cloud networking, software-defined networking, infrastructure automation, and CI/CD practices.
• Practical experience with high-performance and low-latency infrastructure.
• Opportunity to work on technically challenging infrastructure where reliability and performance have a direct business impact.
• International and collaborative working environment.
