Position Summary:

We are seeking a highly skilled Expert Network Engineer with strong Azure networking expertise to join our dynamic team. The ideal candidate will design, implement, and maintain secure, scalable, and highly available network infrastructures across both on-premises and Azure cloud environments.

In this role, you’ll mentor a technical team of engineers, troubleshoot complex issues, optimize network performance, and ensure security and compliance across hybrid architectures. If you’re passionate about network reliability, cloud integration, and data protection, we’d love to meet you!

Key Responsibilities:

• Design, configure, and maintain network devices and services (e.g., routers, switches, firewalls, load balancers, VPNs, QoS) across on-prem and Azure environments.

• Implement and manage Azure networking components — including Azure Virtual Networks (vNETs), VPN Gateways, ExpressRoute, Azure Firewall, Application Gateway, and Network Security Groups (NSGs).

• Perform network maintenance, monitoring, and optimization to ensure high availability and performance.

• Configure and troubleshoot routing protocols (BGP, OSPF) across hybrid environments.

• Manage and troubleshoot IPSec VPN tunnels between on-prem and Azure.

• Implement and enforce network security policies and manage firewall configurations (Cisco ASA, Palo Alto, Azure Firewall, etc.).

• Monitor and analyze Azure Network Watcher, flow logs, and diagnostics for proactive issue detection.

• Provide Level-2/3 support, perform failover testing, and execute root cause analysis (RCA) for incidents.

• Develop and maintain network automation scripts (Python, PowerShell, or Terraform) for configuration consistency and efficiency.

• Work within established change management and configuration standards.

• Select and implement security tools, policies, and procedures to strengthen network protection.

• Collaborate with Cloud, Security, and Infrastructure teams for integrated design and incident resolution.

Requirements:

• Proven experience as a Network Engineer with strong focus on Azure network design, implementation, and troubleshooting.

• Hands-on experience with:

  • Azure networking (vNETs, ExpressRoute, VPN Gateway, Route Server, Application Gateway, NSG, Azure Firewall)

  • Routing protocols (BGP, OSPF) and communication protocols (TCP/IP, QoS, HSRP)

  • Firewalls (Cisco ASA, Palo Alto, or similar)

  • IPSec VPNs and hybrid connectivity setups

• Strong troubleshooting and analytical skills in resolving complex network issues.

• Familiarity with scripting/automation tools (Python, PowerShell, or Perl) for operational efficiency.

• Excellent communication, documentation, and mentoring skills.

• Ability to work in a 24x7 rotational support model.

Qualifications:

• Bachelor’s degree in Computer Science, Information Technology, or a related field.

• 7–8 years of hands-on experience in network engineering, design, and implementation.

• Strong Azure network operations experience required.

• Certifications preferred:

  • CCNP / CCIE (Enterprise, Security, or Service Provider)

  • Microsoft Certified: Azure Network Engineer Associate (AZ-700)

  • CISSP or equivalent security certification is a plus.
