• Coordinate with vendors, system integrators, and internal technical teams to resolve complex network incidents.

Technical Documentation & Governance

• Maintain accurate network topology diagrams, configuration records, technical documentation, and operational procedures.

• Support change management, audit, and compliance activities.

• Ensure network configurations comply with applicable organisational security standards and cloud governance requirements.

• Collaborate with cloud architects and project teams on network design reviews and implementation planning.

• Stay updated on AWS networking technologies, cloud security practices, and relevant government cloud policies and cybersecurity directives.

Required Skills

• Bachelor's Degree in Computer Science, Computing, Electrical Engineering, Information Systems, Information Technology, or a related discipline.

• Minimum 2 years of relevant experience in network engineering, including hands-on exposure to AWS or hybrid cloud networking environments.

• Strong understanding of networking fundamentals including TCP/IP, HTTP/HTTPS, DNS, DHCP, BGP, VPN, routing, and load balancing.

• Hands-on experience with AWS networking services such as VPC, Transit Gateway, Route 53, PrivateLink, Direct Connect, and Elastic Load Balancing.

• Experience configuring and troubleshooting cloud network connectivity and hybrid network environments.

• Knowledge of network segmentation, traffic filtering, firewall policies, and network access controls.

• Experience supporting network security configurations and firewall infrastructure.

• Hands-on experience with Infrastructure as Code and automation tools such as Terraform, AWS CloudFormation, or Ansible.

• Understanding of network architecture, high availability, performance optimisation, and troubleshooting.

• Familiarity with Zero Trust networking principles.

• Experience using network monitoring, logging, and troubleshooting tools.

• Good understanding of Windows and Linux server networking concepts.

• Strong analytical, troubleshooting, and problem-solving capabilities.

• Good communication and stakeholder management skills.

• Ability to collaborate effectively with cloud, infrastructure, cybersecurity, and project teams.

Preferred Skills

• AWS Certified Advanced Networking – Specialty certification.
