Network Engineer

Position Overview:

The Senior Network Engineer is responsible for the advanced design, implementation, optimization, and operational support of an enterprise network infrastructure. This role applies deep technical expertise to deliver reliable, scalable, and secure network solutions across WAN, LAN, wireless, data center, and network access environments.

The Senior Network Engineer leads complex engineering efforts, executes detailed technical designs, and serves as a senior escalation resource for challenging network issues. The role works with a high degree of independence, collaborates closely with architects and cross-functional teams, and provides technical mentorship to other network engineers while remaining strongly hands-on in implementing and maintaining network solutions.

Responsibilities:

• Design, implement, and optimize complex network solutions supporting high availability, performance, and security across enterprise WAN, LAN, wireless, data center, and network access environments.
• Execute detailed engineering designs and implementation plans aligned with established network architectures, standards, and roadmaps.
• Lead complex deployments, upgrades, and technology refreshes, including large-scale or high-risk changes requiring advanced technical expertise.
• Serve as a senior technical resource for routing, switching, segmentation, and network access technologies.
• Implement and enhance network automation using Python, YAML, Ansible, and related tools.
• Participate in proofs of concept and evaluations of new technologies.
• Provide senior-level escalation support for complex or high-impact network incidents.
• Monitor network performance and reliability metrics and identify opportunities for improvement.
• Collaborate with security, systems, operational technology (OT), cloud, and application teams.
• Develop and maintain network documentation, implementation guides, and operational procedures.
• Mentor and provide technical guidance to other network engineers.
• Coordinate advanced troubleshooting and engineering activities with vendors and service providers.
• Participate in on-call rotations and lead complex after-hours maintenance and change activities as required.
• Perform additional senior-level engineering responsibilities as assigned.

Qualifications:

• Bachelor's degree in information systems, computer science, or a related technical field, or equivalent work experience. Typically four years of additional related, progressive work experience would be needed for candidates who do not possess a bachelor's degree.
