We are Optimum!Job SummaryWe are looking for a Network IP Engineer with a "reliability mindset" to join our Core Network team. While this is a "Level 1" position, it is not just a ticket-clearing role, it is a hands-on engineering role focused on the heart of our IP backbone.You will effectively function as a Network Core Engineer, maintaining and expanding our high-performance infrastructure using primarily Juniper, Cisco and Arista equipment. As a Network SRE, you will also help us transition from manual CLI configurations to automated, resilient, and observable network operations.Whether you are a rising junior engineer with strong fundamentals or a seasoned pro looking for a stable, high-impact environment, we want to meet you.

Requirements

• Junos and/or EOS Fluency: Strong hands-on experience with Juniper and/or Arista command-line interface (CLI). You should be comfortable navigating configuration hierarchies, committing changes safely, and troubleshooting operational commands.
• 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. You understand ping, traceroute, and tcpdump/Wireshark.
• Linux/Unix Literacy: Comfortable working in a Linux shell environment.

Nice To Haves

• Juniper/Arista Experience: Familiarity with Juniper Cloud Management & AIOps (MistAI) and/or Arista EOS and CloudVision.
• SRE/DevOps Skills: Basic scripting in Python or experience with Ansible for network automation.
• Certifications: JNCIA or JNCIS (highly preferred), Arista ACE-A, ACE-P or ACE-E (highly preferred), Cisco CCNA/CCNP, or equivalent real-world experience.

Responsibilities

• Core Engineering: Configure, deploy, and troubleshoot IP core infrastructure, focusing on Juniper MX, PTX, or QFX, Cisco Catalyst and Nexus, and Arista 5000 and 7000 Core series routers and switches.
• 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.
• Reliability & Automation: Move away from manual changes. Help us build and run Python scripts or Ansible playbooks to automate config push, validation, and network auditing.
• Observability: Improve our "eyes on the network" by tuning monitoring tools (e.g., Grafana, Sec One, or other standard NMS) to detect issues before they impact our customers.
• Maintenance: Plan and execute network maintenance windows (firmware upgrades, hardware replacements) with a focus on minimizing downtime.
