Position Overview

The Network Engineer Sr. Principal is a high-impact, hybrid role combining the strategic foresight of a Network Architect with the hands-on technical mastery of a Senior Network Engineer. In this position, you will serve as a technical authority for our enterprise network infrastructure.

Core Job Roles & Strategic Responsibilities

• Assistant Network Architect: Serve as technical designer for the network infrastructure, establishing architectural standards, technical roadmaps, and next-generation design patterns (including SD-WAN, Zero Trust, and Cloud/Hybrid integrations).

• Engineering Authority: Act as the ultimate technical escalation point for critical network operations, overseeing the implementation of complex network modifications, migrations, and hardware refreshes.

• Technical Mentor & Advisor: Mentor senior and junior engineering staff, cultivate a culture of technical excellence, and serve as the primary advisor to executive leadership on emerging networking technologies and budget forecasts.

• Security & Compliance Steward: Partner with the cybersecurity team to design and enforce defense-in-depth network architectures, ensuring strict alignment with security protocols, compliance frameworks, and industry best practices.

Daily & Operational Duties

• Architectural Blueprinting: Design end-to-end logical and physical network topologies, IP routing schemes, and traffic engineering strategies using advanced design software.

• Hands-on Implementation: Lead the configuration, deployment, and optimization of core enterprise network devices, including backbone routers, multi-layer switches, next-generation firewalls, and application delivery controllers.

• Automation Development: Write, review, and maintain production-grade automation scripts and configuration playbooks using tools such asPython, Ansible, and Terraform to eliminate manual configuration drift.

• Vendor and Capacity Analysis: Analyze network telemetry data to monitor capacity thresholds, proactively design expansion plans, and lead technical evaluations/proof-of-concepts with major hardware and cloud vendors.

• Advanced Troubleshooting: Provide Tier 4 escalation support for complex network outages, utilizing packet-capture analysis (Wireshark) and telemetry tools to perform root-cause analysis on highly elusive issues.

• Collaborative Planning: Author comprehensive engineering specifications, deployment guides, and operational standard operating procedures (SOPs) to ensure smooth handoffs to network operations teams
