## About the Role

Must-Have Skills:

 * Hybrid Networking Fluency: Strong hands-on experience with hardware CLIs (Juniper Junos and/or Arista EOS) alongside a working knowledge of cloud-native networking concepts in GCP (VPC architecture, firewall rules, and cloud routing).
 * Networking Fundamentals: Deep understanding of the TCP/IP stack, subnetting, and core routing protocols (specifically BGP and OSPF).
 * Troubleshooting Logic: Ability to trace a packet from A to B and identify where it drops, whether that requires standard CLI tools (ping, traceroute, tcpdump/Wireshark) or analyzing VPC Flow Logs.
 * Linux/Unix Literacy: Comfortable working in a Linux shell environment.

Nice-to-Have (Bonus Points):

 * Cloud Certifications: Google Cloud Professional Cloud Network Engineer or Google Cloud Associate Cloud Engineer (highly preferred).
 * Hardware Certifications: JNCIA or JNCIS, Arista ACE-A/ACE-P/ACE-E, or Cisco CCNA/CCNP.
 * SRE/DevOps Skills: Basic scripting in Python or experience with Infrastructure as Code (IaC) tools like Ansible and Terraform for network automation.
 * Vendor Platforms: Familiarity with Juniper Cloud Management & AIOps (MistAI) and/or Arista EOS and CloudVision.

## Description

You will effectively function as a Network Core Engineer, maintaining and expanding our high-performance infrastructure bridging our physical hardware (primarily Juniper, Cisco, and Arista) and our Google Cloud Platform (GCP) environments. As a Network SRE, you will also help us transition from manual CLI configurations to automated, resilient, and observable network operations across both on-premise and cloud boundaries., * Core & Cloud Engineering: Configure, deploy, and troubleshoot infrastructure across our physical IP core (Juniper MX/PTX/QFX, Cisco Catalyst/Nexus, Arista 5000/7000) and our cloud environments (GCP VPCs, Subnets, Cloud Routers, and Cloud Load Balancing).

 * Incident Response: Act as the first line of defense for complex network issues. Investigate routing anomalies, packet loss, and latency issues using a blameless root-cause analysis approach across both physical links and cloud perimeters (e.g., Cloud VPN, Dedicated Interconnect).
 * Reliability & Automation: Move away from manual changes. Help us build and run Python scripts, Ansible playbooks, and Terraform configurations to automate deployments, validate changes, and audit our hybrid network.
 * Observability: Improve our "eyes on the network" by tuning monitoring tools (e.g., Grafana, standard NMS) and utilizing GCP's native observability (Cloud Monitoring, Cloud Logging, Network Intelligence Center) to detect issues before they impact our customers.
 * Maintenance: Plan and execute network maintenance windows (firmware upgrades, hardware replacements, cloud architecture migrations) with a focus on minimizing downtime.

The Stack

 * Primary Hardware Vendors: Juniper Networks (Junos OS), Arista Networks (EOS), Cisco (IOS XE and NX-OS)
 * Cloud Platform: Google Cloud Platform (VPC, Cloud DNS, Cloud NAT, Cloud Interconnect/VPN, Cloud Armor)
 * Protocols: BGP, OSPF/IS-IS, EIGRP, MPLS, LDP/RSVP, EVPN/VXLAN.
 * Automation: Python, Ansible, Terraform, Git.
