Role Description Responsible for designing, developing and implementing scalable, maintainable, highly available network architectures that support network infrastructure and meet business objectives. Responsible for providing client support for network infrastructure including advanced design, setup and support of systems. How You’ll Make an Impact - Configure and install various network devices and services - Perform network maintenance and system upgrades including service packs, patches, hot fixes and security configurations - Monitor performance and ensure system availability and reliability What You’ll Actually Do - Monitor system resource utilization, trending, and capacity planning - Provide senior level support and troubleshooting to resolve issues - Work within established configuration and change management policies to ensure awareness, approval and success of changes made to the network infrastructure - Select and implement security tools, policies, and procedures in conjunction with the company’s security team - Liaise with vendors and other IT personnel for problem resolution - Properly set the scope and timelines of new projects to meet completion deadlines - Demonstrate the ability to prioritize and manage competing demands and tasks and successfully manage multiple engagements that may require additional resources - Interface with all levels of employees internally and within client businesses to support program requirements (business owners, project managers, customer employees and customers’ executive management) - Provide technical guidance to other IT professionals to correct problems encountered with network software and connectivity - Design, install, and support Route/Switch environments - Design, install, and support firewall environments - Monitoring network engineering performance and ensure system availability and reliability - Identifying and implementing work efficiencies through process improvement techniques - Other computer operations work as required

• Work on network infrastructure projects, ensuring the correct definition, deployment and sustainment of connectivity solutions. • Plan, implement and oversee changes in LAN, WAN and WLAN environments, ensuring adherence to technical and business requirements. • Develop configuration standards, technical documentation and best practices for Routing & Switching environments. • Participate in the design, implementation and evolution of network security solutions, including firewalls, segmentation and access policies. • Work on projects involving equipment and solutions from Cisco, Fortinet, Check Point and Palo Alto. • Implement and support secure network access solutions, including authentication technologies such as 802.1X, MAB, RADIUS and TACACS+. • Administer and evolve NAC solutions, especially Cisco ISE, including authentication policies, device profiles and integrations with Active Directory. • Participate in technology modernization projects, environment migrations, security initiatives and digital transformation efforts. • Work on connectivity and integration projects for Azure Cloud environments, including hybrid networking. • Support troubleshooting activities and root cause analysis for high-complexity incidents related to network infrastructure. • Create and maintain technical documentation, architecture diagrams, operational procedures and project documentation. • Collaborate with multidisciplinary teams, vendors and clients during the planning, deployment and transition phases of solutions.

• Audit network routing and architecture (BGP, OSPF, MPLS), verifying hierarchy and integration of edge and core devices. • Evaluate the IPv4/IPv6 addressing plan, identifying prefix overlaps or underutilized blocks. • Collect and analyze performance metrics (latency, jitter, packet loss) to content servers such as Google, Netflix, and Cloudflare. • Review and audit logical security filters, anti-spoofing measures, and DDoS mitigation policies. • Assess the operational maturity of NOC tools (e.g., Zabbix, Grafana), verifying the reliability and quality of data collection. • Compare Q&A responses with the actual network configuration, identifying gaps and inconsistencies. • Audit access control lists (ACLs) and firewall policies, ensuring that only authorized traffic is allowed. • Evaluate network plant equipment for obsolescence, compatibility, scalability, and technical quality. • Validate legacy technologies (radio, coaxial, licensed radio) and propose migration to fiber optic when necessary. • Draft **technical audit reports**, classifying risks as Low, Medium, or Critical.

• Design, implement, and evolve national multi-service backbone architectures using MPLS, BGP, IGP, L2VPN/L3VPN, EVPN, and Segment Routing; • Define technical standards, routing policies, peering strategies, and technology evolution roadmaps for customer networks; • Serve as the last escalation level for critical incidents, leading advanced troubleshooting and structural production changes; • Conduct capacity, resilience, and performance analyses in carrier-grade environments; • Mentor N1, N2, and N3 teams, promoting technical development and dissemination of best practices; • Represent IPV7 in technical meetings, strategic projects, complex pre-sales, and interactions with large enterprise clients; • Contribute to the continuous evolution of architectures, processes, and operational standards within the sector.
