Senior Network Engineer

As a Senior Network Engineer, you will play a critical role in the planning, deployment, and ongoing performance of our FTTx XGS-PON access, transport, and core network infrastructure. You will play a key role in the design and execution of network initiatives, ensuring timely, resource-efficient implementations and rigorous testing to meet performance expectations. In parallel, you will monitor network health, troubleshoot complex issues, and drive continuous optimization to maintain high availability and service level agreement (SLA) compliance.

Your technical expertise will be essential in fostering operational excellence, supporting cross-functional collaboration, and mentoring team members to elevate the organization’s overall network capabilities.

• Monitor performance and availability of the access, core, and transport infrastructure using advanced network monitoring platforms.
• Proactively identify, diagnose, and resolve network issues to minimize downtime and ensure compliance with SLAs.
• Analyze network performance data to drive capacity planning, service optimization, and automation initiatives for improved efficiency.
• Lead the coordination and resolution of network incidents and problems, including root cause analysis and corrective actions.
• Manage escalations and ensure timely resolution of issues identified through monitoring or reported by end users.
• Execute planned changes—such as firmware upgrades, configuration modifications, and hardware replacements—using formal change control processes.
• Collaborate with architects and stakeholders to design scalable, reliable, and high-performance network solutions across the access, core, and transport layers.
• Develop and present Proof of Concepts for new network technologies and infrastructure strategies.
• Conduct rigorous testing and verification of deployed network systems to ensure compliance with performance and reliability standards.
• Maintain up-to-date documentation including detailed network diagrams, equipment inventories, test plans, procedures, and configuration records.
• Enforce security best practices to safeguard network infrastructure against threats and unauthorized access.
• Ensure operational adherence to regulatory requirements and industry standards.
• Collaborate with equipment vendors to resolve hardware and software issues, coordinate support and manage upgrades.
• Collaborate cross-functionally to ensure alignment, seamless execution, and operational readiness across all phases of network initiatives.
• Support the development of customer-driven products and service roadmaps that enhance satisfaction and meet evolving demands.
• Serve as a senior technical resource and mentor to junior engineers and peers, promoting technical knowledge, sharing, and professional development.
• Provide training on procedures, technologies, and best practices to ensure team consistency and growth.
• Work in a round-the-clock environment, 365 days a year, to promptly address critical technical operational emergencies as part of an on-call rotation.
• Maintains/obtains industry-standard certifications and education as required/preferred.

• Proven experience as a Network Engineer, preferably in a service provider environment with responsibility for access, transport, and/or core networks. Experience with FTTx and XGS-PON technologies is strongly preferred.
• In-depth knowledge of XGS-PON network architecture, protocols, and standards, including provisioning, performance tuning, and fault isolation within a production environment.
• Strong understanding of IP networking concepts, including routing protocols (OSPF, BGP), MPLS, switching, VLANs, subnetting, and QoS. Familiarity with carrier-grade network design and business-class service delivery is a plus.
• Proficient with MPLS traffic engineering.
• DHCP and DNS administration.
• Voice-over-Internet Protocol (VoIP).
• Understanding of IPv4 and IPv6 addressing fundamentals.
• Strong technical, analytical, and organizational skills associated with design and implementation of complicated service provider architectures and applications.
