IP Engineer III – Wireline/Fiber- Dallas or Houston, TX

Work Arrangement: Hybrid – 2 days onsite per week (Wednesday & Thursday)

Job Overview

We are seeking an experienced IP Engineer III – Wireline/Fiber to join a leading service provider network engineering team. This senior-level position will focus on the design, implementation, optimization, and troubleshooting of carrier-grade IP/MPLS networks across core, edge, aggregation, and transport environments.

The ideal candidate will have deep hands-on experience in large-scale service provider networks, strong troubleshooting capabilities, and the ability to work across Juniper, Cisco, Nokia, Ciena, and other multi-vendor platforms.

This is a technical leadership role with no direct reports. The engineer will lead complex network initiatives, operational escalations, migrations, capacity planning, and network architecture improvements.

Key Responsibilities

• Design, implement, maintain, and troubleshoot carrier-grade IP/MPLS networks.
• Support core, edge, aggregation, and transport network environments.
• Engineer and troubleshoot BGP, IS-IS, OSPF, MPLS, L2VPN/L3VPN, VPLS, and traffic engineering.
• Design and optimize RSVP-TE networks, including primary, secondary, and tertiary LSPs and node/link protection.
• Lead network migrations, upgrades, expansions, and technology deployments with minimal service disruption.
• Perform network health assessments, capacity planning, augmentation reviews, and proactive network optimization.
• Troubleshoot complex network issues and serve as a technical escalation point for operational incidents.
• Develop and maintain network architecture, design documentation, standards, MOPs, and operational procedures.
• Collaborate with transport/optical engineering teams on IP-to-transport connectivity and network handoffs.
• Support network integration and consolidation across multiple acquired or partially merged networks.
• Mentor junior engineers and provide technical guidance on complex network issues.
• Participate in change management, maintenance windows, and an on-call rotation.
• Identify opportunities for network automation and operational efficiency.

Required Qualifications

• 10–15 years of experience in carrier, telecommunications, or large-scale service provider networking.
• Expert-level knowledge of MPLS, including LDP, RSVP-TE and/or Segment Routing.
• Strong hands-on experience with L2VPN, L3VPN, VPLS, and carrier Ethernet.
• Deep BGP experience, including routing policies, communities, route reflectors, and peering.
• Strong knowledge of IS-IS and OSPF in large-scale routed environments.
• Hands-on production experience with multiple network vendors, including Juniper, Cisco, Nokia, and/or Ciena.
• Strong understanding of IPv4/IPv6, QoS, high availability, and network resiliency.
• Experience troubleshooting complex service provider networks.
• Strong communication and technical documentation skills.
• Ability to work independently and lead complex technical initiatives.

Preferred Qualifications

• Experience with DWDM, ROADM, coherent optics, and optical transport networks.
• Experience with Python, Ansible, NETCONF/YANG, gNMI, Git, or other network automation technologies.
• Experience with Juniper Space or similar network management platforms.
• Knowledge of Segment Routing, EVPN, DCI, and backbone network expansion.
• Experience supporting network integration following acquisitions or major network migrations.
• Industry certifications such as JNCIP/JNCIE, CCNP/CCIE Service Provider, Nokia NRS, or Ciena certifications.

What We're Looking For

The successful candidate will be a hands-on technical leader who can work effectively in a complex, multi-vendor service provider environment. The network is undergoing modernization and migration from a Nokia-centric environment toward Juniper, while continuing to operate Brocade, ADTRAN, Cisco, and other platforms.

Experience working across multiple networks, troubleshooting complex environments, and driving network modernization initiatives will be highly valued.
