Sr. Network Engineer (Telecom)

Senior Network Engineer
DFW (on-site) | Full-time | 10+ years experience required We're looking for a Senior Network Engineer to take ownership of complex, large-scale network infrastructure — designing for resilience, optimizing for performance, and ensuring the reliability that our operations depend on. If you're energized by hard routing problems, mentoring other engineers, and building networks that genuinely have to work, this role is for you.
What You'll Do

• Architect, deploy, and manage enterprise-scale network infrastructure in line with long-term technical strategy and organizational standards.
• Configure, tune, and troubleshoot routing protocols across BGP and OSPF environments at scale.
• Design and maintain robust Layer 2, Layer 3, and MPLS environments that meet demanding availability requirements.
• Apply hands-on knowledge of high-capacity transport and physical connectivity to support resilient end-to-end network design.
• Lead routine and advanced maintenance cycles — upgrades, patching, and security hardening — with minimal disruption.
• Perform capacity modeling, traffic analysis, and performance forecasting to stay ahead of growth.
• Provide technical leadership and mentorship to junior and mid-level engineers on the team.
• Drive proactive network monitoring and optimization practices, reducing mean time to resolution.
• Own network security posture and ensure ongoing compliance with industry best practices.
• Create and maintain thorough documentation covering design decisions, configurations, and operational runbooks.

What You Bring

• 10 or more years of hands-on experience in large-scale network engineering environments.
• Deep working knowledge of BGP and OSPF in complex, high-demand production environments.
• Proven experience designing and operating Layer 2, Layer 3, and MPLS networks in production.
• Bachelor's degree in Computer Science, Information Technology, or a closely related field.
• Substantial hands-on experience with Juniper and Cisco platforms in large-scale environments.
• Advanced industry certifications in networking are a strong differentiator and highly preferred.
• Solid grounding in network security principles, threat modeling, and defensive network architecture.
