About the RoleWe are seeking a proactive and detail-oriented
Network Engineer to join our infrastructure team. In this role, you will be responsible for configuring, maintaining, and securing our core enterprise networking infrastructure, virtual environments, Linux systems, and secure remote-access connections.
You will work closely with our engineering team to maintain high system availability, implement Linux-based firewall rules, build and maintain secure VPN tunnels, and automate routine operational tasks using languages like Python and Bash. This position is ideal for a growing engineer looking to expand their technical capabilities in network security, virtualization, automated cloud orchestration, and advanced encryption frameworks.
Key Responsibilities- Core Network Operations: Configure, maintain, and troubleshoot enterprise network hardware, including Ciscorouters, switches, and firewalls.
- VPN & Secure Connectivity: Design, deploy, and support site-to-site and remote-access VPNs (IPsec, OpenVPN, WireGuard) to ensure encrypted, secure communications.
- Linux Security & Administration: Configure and manage Linux firewalls (iptables, nftables, ufw) alongside general Linux server administration (DNS, DHCP, SSH, Syslog).
- Network Automation & Scripting: Write and maintain basic programs/scripts using Python, Bash, or similar languages to automate system backups, log parsing, and routine network monitoring tasks.
- Virtualization Support: Support network configurations and virtual bridging across Virtual Machines (VMs) and hypervisors (e.g., VMware ESXi, KVM, Proxmox).
- Troubleshooting & Remediation: Diagnose and resolve Layer 1 through Layer 7 network incidents, packet loss, routing failures, and performance bottlenecks using traffic analysis tools.
- Documentation & Compliance: Maintain precise topology diagrams, IP address management (IPAM), and operational runbooks.
Required Qualifications- 2–5 years of hands-on experience in network administration or network engineering.
- Hands-on experience with Linux Systems Administration (Ubuntu, RHEL, CentOS, or Rocky Linux) and command-line management.
- Solid experience configuring Linux Firewalls (iptables, nftables, ufw) and system security controls.
- Practical experience configuring and troubleshooting VPN technologies (IPsec, OpenVPN, WireGuard).
- Proficiency in basic programming/scripting using Python, Bash, or similar languages for task automation.
- Practical experience managing networking within Virtual Machine environments (vSwitches, virtual bridges, hypervisors).
- Core networking protocol expertise: TCP/IP, Subnetting, DNS, DHCP, SNMP, and HTTP/S.
Desired Skills- Infrastructure Automation & Orchestration: Experience with automation and configuration management tools like Ansible, as well as cloud orchestration frameworks (e.g., Terraform, CloudFormation).
- Container Networking: Familiarity with containers and container networking concepts (e.g., Docker, Kubernetes CNI plugins).
- Network Encryption Experience: Familiarity with network encryption protocols and security products (e.g., TLS/SSL, MACsec, hardware encryptors).
- Industry certifications such as CCNA, CompTIA Security+, or Linux Professional Institute (LPIC-1 / RHCSA).
- Experience with network monitoring tools (e.g., Wireshark, Nagios, Zabbix, PRTG).
