Job description

Network Engineer

We are looking for an experienced Network Engineer to design, implement, and support robust, scalable, and secure network infrastructure across global environments. This role requires hands-on expertise in enterprise networking technologies, cloud connectivity, and routing protocols, with a focus on performance, availability, and business continuity.

Key Responsibilities

• Network Design & Implementation

  • Design, deploy, and manage global WAN and SD-WAN architectures to ensure scalability, high availability, and cost-efficiency.

  • Implement advanced routing protocols (BGP, OSPF, EIGRP) across complex network topologies.

  • Manage enterprise Wi-Fi networks and optimize wireless performance.

• Cloud & Hybrid Connectivity

  • Establish and maintain hybrid connectivity between on-premises environments and public cloud platforms (Azure, AWS).

  • Configure cloud networking components including VPCs, VPNs, ExpressRoute, and Direct Connect.

  • Integrate cloud services with enterprise networks, ensuring security and reliability.

• Traffic Management & Optimization

  • Define and implement QoS policies to prioritize critical application traffic (VoIP, video, business systems).

  • Monitor and troubleshoot issues related to latency, packet loss, and bandwidth utilization.

• Operations & Monitoring

  • Maintain network uptime, performance, and compliance with standards (ISO 27001, NIST).

  • Configure monitoring tools and support HA and disaster recovery strategies.

  • Serve as an escalation point for complex incidents and participate in on-call rotations.

• Collaboration & Documentation

  • Work with cross-functional teams and global peers to support infrastructure projects and operations.

  • Maintain detailed documentation of network configurations, topologies, and policies.

  • Provide mentorship to junior team members and contribute to technical knowledge sharing.

Required Experience & Skills

• Experience:

  • 6–10 years in network engineering roles within enterprise-scale environments.

  • Proven experience with global WAN management and SD-WAN deployments.

  • Hands-on experience with cloud networking (Azure/AWS) and hybrid architectures.

  • Experience supporting distributed teams and infrastructure across multiple regions.

• Technical Proficiency:

  • Deep understanding of routing and switching technologies (Cisco, Arista, Brocade)

  • Expertise in SD-WAN solutions (e.g., CATO, Palo Alto, Silver Peak).

  • Strong background in QoS configuration, traffic shaping, and network performance tuning.

  • Familiarity with network security tools and protocols (IPsec, SSL, IDS/IPS, firewalls).

  • Proficient in network monitoring platforms (e.g., SolarWinds, Wireshark, Scrutinizer).

• Education & Certifications:

  • Bachelor’s degree in Computer Science, Network Engineering, or related field (or equivalent experience).

  • Preferred certifications: CCNP, CCIE, AWS Certified Advanced Networking, Azure Network Engineer Associate.
