Junior Network Engineer (Switching and Routing) job at Q-Sourcing

Key Responsibilities

A. Network Configuration & Support

• Configure, maintain, and troubleshoot Layer 2 and Layer 3 network devices (switches, routers, firewalls).
• Implement and support VLANs, trunking, inter-VLAN routing, and network segmentation.
• Monitor network performance, identify bottlenecks, and resolve connectivity issues.

B. Switching (Layer 2)

• Configure VLANs, trunk ports (802.1Q), EtherChannel (LACP/PAgP), and switching logic.
• Implement STP, RSTP, and MSTP to ensure loop-free network topology.
• Maintain MAC address tables and support switching-related troubleshooting.
• Apply port security, storm control, and switch hardening to improve network security.

C. Routing (Layer 3)

• Configure static and dynamic routing as required.
• Implement routing protocols such as OSPF, EIGRP, IS-IS, and BGP.
• Perform route summarization, route filtering, and redistribution.
• Implement high availability routing technologies: HSRP, VRRP, GLBP.
• Support policy-based routing (PBR) and routing optimization.

D. Network Services & Fundamentals

• Manage and troubleshoot DHCP, DNS, NAT, PAT, ARP, and other core network services.
• Perform IPv4/IPv6 addressing, subnetting, and supernetting.
• Ensure accurate network documentation (topologies, IP schemes, device configurations).

E. Network Monitoring & Security

• Monitor network health using standard monitoring tools.
• Support access control, ACLs, and device hardening.
• Respond to network security alerts and assist with threat mitigation.

Requirements

• Bachelor’s degree in Computer Science, Information Technology, Telecommunications, or related field.
• 2–4 years of hands-on experience in enterprise switching and routing.
• Experience supporting Cisco, Huawei, Juniper, or HP switches/routers.
• Demonstrable understanding of OSI & TCP/IP models.
• Strong knowledge of IPv4/IPv6 subnetting and network services (DNS, DHCP, NAT/PAT).

Preferred Certifications (Added Advantage)

• CCNA (Cisco Certified Network Associate) – strongly preferred.
• HCIA (Huawei Certified ICT Associate).
• JNCIA (Juniper Networks Certified Associate).
• Any certification in Networking, Security, or Systems Administration.
