Network Administrator

Role & responsibilities

We are looking for a proactive Junior Network Architect (L2) with 3+ years of hands-on experience in enterprise networking. In this role, you will bridge day-to-day operations and network architecture, assisting senior architects in evaluating, designing, and optimizing robust enterprise networks. You will configure and maintain Layer 2/Layer 3 campus networks, secure perimeter firewalls, manage wireless deployments, and provide advanced L2 escalations to ensure 99.9%+ availability and security across our multi-site environment.

Key Responsibilities

Architecture & Implementation

• Assist Senior Network Architects with low-level design (LLD), capacity planning, and deployment of enterprise LAN, WAN, SD-WAN, Wi-Fi, and VPN topologies.

• Stage, configure, and commission Layer 2 and Layer 3 switches, routers, and next-generation firewalls (NGFW).

• Implement core protocols and network services including VLANs, trunking, Spanning Tree (RSTP/MSTP), OSPF/BGP, DHCP, DNS, and IPAM.

• Collaborate with Cloud and Systems teams to integrate on-premises infrastructure with hybrid-cloud environments (AWS / Azure).

Network Operations & Security

• Administer enterprise firewalls, managing stateful access control lists (ACLs), NAT rules, IPS/IDS profiles, SSL inspection, and IPsec/SSL VPN tunnels.

• Act as an advanced escalation point (L2) for recurring or complex incidents involving routing anomalies, latency, packet loss, and hardware faults.

• Support enterprise wireless infrastructure, including central controllers (WLC), access points, SSID security policies, and RF performance optimization.

• Liaise with telecommunications carriers and ISPs for circuit turn-up, failover testing, and link outage resolution. Governance, Monitoring & Reliability

• Proactively monitor network health, bandwidth utilization, and interface errors using tools such as PRTG, Zabbix, or SolarWinds.

• Plan and execute firmware updates, security patching, and scheduled change windows in compliance with ITIL change management procedures.

• Author and maintain high-quality network topology diagrams (Visio/Lucidchart), configuration templates, and standard operating procedures (SOPs).

• Participate in disaster recovery drills, vulnerability assessments (VAPT remediation), and compliance audits (ISO 27001 / SOC 2). Required Skills & Qualifications

• Core Networking: Strong grasp of the OSI model, TCP/IP stack, dynamic routing (OSPF, basic BGP), Layer 2 switching (VLANs, 802.1Q, LACP, STP), and IP addressing/subnetting.

• Firewall Engineering: Hands-on experience configuring and administering enterprise firewalls (Fortinet FortiGate, Palo Alto, Sophos, or Cisco ASA/Firepower).

• Hardware & Platforms: Proven track record configuring campus-grade switches and routers (Cisco Catalyst, Aruba/HPE, or equivalent enterprise hardware).
• • Network Services & Tools: Practical knowledge of IPsec/SSL VPNs, enterprise Wi-Fi deployment, packet analysis (Wireshark), and network monitoring platforms.
• • Problem-Solving & Communication: Strong diagnostic reasoning with the ability to lead incident post-mortems and articulate architectural trade-offs to cross-functional engineering teams. Preferred Qualifications & Certifications

• Education:

• Bachelors degree in Computer Science, Information Technology, Electronics Engineering, or equivalent practical experience.
• • Core Certifications: Cisco Certified Network Associate (CCNA) required; active progress toward Cisco Certified Network Professional (CCNP Enterprise) strongly preferred.
• • Security & Vendor Certifications: Fortinet NSE 4+, Palo Alto PCNSA/PCNSE, or Aruba Certified Associate/Professional.
• • Modern Networking: Practical exposure to SD-WAN architectures, network automation (Python, Ansible), or cloud virtual networking (AWS VPCs, Transit Gateways, Azure VNets).
• • Process Knowledge: Familiarity with ITIL frameworks, change advisory boards (CAB), and enterprise security hardening guidelines.
