Network Engineer L3

Deployment & Operations: Deployment, configuration, and maintenance of network hardware (routers, switches, firewalls) from Cisco and Palo Alto (C9200, C9300X, C9200, PA5500). Ensure all network systems adhere to security and compliance standards. Make sure there is the least user interruption with any deployment or migrations.

Troubleshooting & Resolution: Troubleshooting of complex network issues, performing deep-dive analysis, root cause isolation, and permanent resolution for incidents affecting end users.

Automation: Develop and implement network automation tools and scripts (e.g., using Python, Ansible, Terraform) to streamline operational tasks, provisioning, and configuration management.

Performance Tuning: Proactively monitor network performance and capacity, identifying bottlenecks and implementing optimizations to improve latency and throughput., Configuration of all network hardware (C9200-24PXG, C9300X-48TX) along with helping with cabling issues

Migration phase (starting 2026-02-24 up to June)

Migrate the network for all cells after coordination with the research teams (one cell at a time), ensuring transition as smooth as possible with minimum user disruption

BAU phase

Turning up the network hardware for any new cells

Troubleshooting network issues

Creating vlans or changing vlans

Documenting any changes in the IP/vlan spreadsheet

Updating firewall policies based on issues and user requirements

Do you have experience in VLAN?, Do you have a Master’s degree?, 7+ years of progressive experience in an enterprise and large-scale network engineering, design, and operations, preferably within an ISP, large enterprise, or cloud/tech environment.

Good to have Linux Operating system experience.
