• Troubleshoot connectivity and routing issues across hybrid environments.

3. Network Security & Compliance

• Implement network security best practices including network segmentation, firewall policies, WAF rules, logging, monitoring, encryption, and controlled access.

• Support security controls such as IDS/IPS, micro-segmentation, Zero Trust principles, and secure access models.

• Ensure network changes comply with enterprise security standards, change management processes, and governance requirements.

• Participate in security reviews, audit-readiness activities, vulnerability remediation, and compliance initiatives.

4. Automation & Infrastructure as Code

• Develop and maintain reusable Infrastructure as Code (IaC) templates for cloud networking components using Terraform or equivalent tools.

• Automate network provisioning, configuration validation, policy enforcement, and operational processes.

• Use Ansible, Python, Shell scripting, or similar technologies to improve network automation and operational efficiency.

• Support CI/CD and DevOps practices for controlled deployment of network and infrastructure changes.

5. Monitoring, Incident & Problem Management

• Implement and maintain monitoring, alerting, and logging for network availability, latency, throughput, connectivity, and security events.

• Perform incident triage, troubleshooting, root cause analysis, and resolution for connectivity, routing, DNS, firewall, and performance-related issues.

• Participate in major incident management and provide timely technical updates to stakeholders.

• Contribute to problem management and continuous service improvement initiatives to reduce recurring incidents.

6. Documentation & Stakeholder/Vendor Collaboration

• Create and maintain network architecture diagrams, configuration documentation, operational runbooks, SOPs, and troubleshooting guides.

• Collaborate with cloud service providers, network vendors, security teams, infrastructure teams, and managed service providers.

• Provide technical inputs for solution reviews, change approvals, transition planning, and operational governance forums.

• Communicate technical issues, risks, and recommendations effectively to both technical and business stakeholders.

Essential Skills & Qualifications

• Bachelor's degree in Computer Science, Information Technology, Network Engineering, or a related field.

• Proven experience as a Cloud Network Engineer or Cloud Infrastructure Engineer supporting enterprise cloud environments.

• Strong hands-on knowledge of cloud networking services across AWS and GCP, including:

  • VPC/VNet

  • Subnets

  • Route tables

  • NAT

  • Peering

  • Internet/NAT Gateways

  • DNS

  • Load Balancing

  • Network connectivity services

• Hands-on experience with hybrid connectivity technologies such as:

  • VPN

  • AWS Direct Connect

  • Azure ExpressRoute

  • Google Cloud Interconnect

  • SD-WAN

  • MPLS

  • Internet edge connectivity

• Strong understanding of networking fundamentals including TCP/IP, routing, switching, BGP, OSPF, firewall policies, network segmentation, and high-availability network design.

• Experience with network security technologies and concepts including firewalls, WAF, IDS/IPS, micro-segmentation, Zero Trust, encryption, and secure access models.

• Experience with Infrastructure as Code and automation, particularly Terraform, Ansible, Python, and/or Shell scripting.

• Familiarity with cloud governance, compliance, logging, monitoring, and enterprise operational best practices.

• Strong troubleshooting skills across connectivity, latency, DNS, routing, firewall/security policies, and application access issues spanning cloud and on-premises environments.

• Strong communication, documentation, stakeholder management, and collaboration skills.

The ideal candidate is a hands-on Cloud Network Engineer who can independently manage AWS/GCP networking and hybrid connectivity, troubleshoot complex enterprise network issues, automate infrastructure using Terraform and scripting, and work effectively across network, cloud, security, application, and vendor teams.
