Senior Network Engineer (Data Center & Enterprise)

About the Role

We are seeking a highly skilled and experienced Senior Network Engineer on behalf of our client to design, implement, maintain, and automate robust data center and enterprise network infrastructures.

This is a critical role requiring a rare technical trifecta: hands-on, expert-level mastery across Cisco, Juniper, and Micas platforms. If you are a seasoned engineer who thrives in complex, multi-vendor environments, loves bridging the gap between physical infrastructure and cutting-edge network automation, and enjoys mentoring junior talent, we want to hear from you.

Key Responsibilities

• Multi-Vendor Infrastructure Management: Oversee, configure, and troubleshoot complex data center and enterprise environments spanning Cisco, Juniper, and Micas platforms.

• Advanced Routing & Switching: Maintain high-availability network architectures utilizing advanced Layer 1–3 protocols ($BGP$, $OSPF$, $MPLS$, $VRF$, and multicast).

• Network Automation: Drive efficiency by developing and implementing automation workflows, infrastructure as code (IaC), and scripting solutions.

• Physical DC Operations: Oversee structured cabling, fiber optics, and physical space planning within the data center environment.

• Security & Compliance: Enforce robust network security postures across multi-vendor environments using AAA, 802.1X, ACLs, and firewalls.

• Monitoring & Documentation: Utilize DCIM and observability tools to ensure uptime, and author comprehensive technical documentation (SOPs, MOPs, and detailed network diagrams).

• Leadership & Mentorship: Act as a technical escalation point and provide guidance, coaching, and mentorship to junior and mid-level engineering staff.

Required Technical Skills & Qualifications

• DCIM & Monitoring: Experience with NetBox, Splunk, ELK stack, or similar observability platforms.

Security & Physical Infrastructure

• Security: AAA, 802.1X, ACLs, and multi-vendor firewall administration.

• Physical Layer: Solid understanding of structured cabling, fiber optic types, and physical data center layout/operations.

Documentation & Certifications

• Strong track record of creating SOPs, MOPs, and network diagrams.

• Minimum Certification: CCNA required.

• Preferred Certification: CCNP, JNCIP, or equivalent multi-vendor certifications are strongly preferred.
