We are strengthening our 10 member Infrastructure IT engineering team and are looking for a Senior Engineer to help design, build, automate and operate our next-generation SD-WAN platform-based solution. You will combine deep networking expertise with platform engineering and automation. Your work will shape how sites are connected, secured, deployed and supported at scale with strong focused on automation part.  

This is not a narrow operations role. You will influence architecture, create reusable standards and automation, lead complex implementations and migrations, and own service reliability throughout the full product lifecycle.

• Engineer and manage core head-end infrastructure of global WAN enterprise-grade solution.

• Work closely with network, security, cloud, architecture, service-management teams, telecom carriers and strategic partners.  
• Mentor other engineers and raise the quality of designs, documentation and engineering practices.  

Why this role matters

• You will help define a strategic connectivity platform rather than only maintain an existing network.  
• You will have room to automate at scale and influence engineering standards and technical roadmap decisions.  
• Your work will directly improve deployment speed, service resilience, security and user experience across a distributed organization.  
• You will collaborate with experienced infrastructure, security and automation professionals in an international environment.  

What you bring

• Several years of hands-on experience with enterprise WAN, SD-WAN or network architecture and engineering.  
• Strong routing and network security fundamentals, including BGP, OSPF, VRF or VPN segmentation, QoS, NAT and IPsec.  
• Strong expertise in at least one enterprise SD-WAN platform (Cisco, Versa, PAN) is highly valued.  
• Practical automation experience with Python, REST APIs and Git; Ansible, Terraform or CI/CD experience is an advantage.  
• Experience and orientation in development principles.  
• Experience troubleshooting business-critical networks and working within structured incident, problem and change-management processes.  
• Ability to turn complex requirements into clear designs, standards, and implementation plans.  
• Professional English, strong ownership and confidence working across international teams.
