What we expect from you 

• BSc or equivalent in Computer Science, Electrical/Electronic Engineering, or related field.

• Solid understanding of computer networking concepts (TCP/IP, routing, switching, subnetting).

• Hands-on experience with network design, including VLANs, IP planning, and segmentation.

• Experience configuring and managing firewalls.

• Understanding of network security principles (least privilege, segmentation, access control).

• Experience in troubleshooting network issues in complex environments.

• Familiarity with Windows and Linux systems.

• Ability to interpret system communication requirements and translate them into network configurations.

• Good analytical and problem-solving skills.

• Good interpersonal skills and ability to work in multidisciplinary teams.
