Network Implementation Engineer Job Whippany New Jersey USA,IT/Tech

Responsibilities:

Produce low level design deliverables for new sites and expansions, including routing, switching, firewall, wireless, and data center connectivity components
Build complete bill of materials, size hardware and circuits, and drive procurement activities including ordering network gear and carrier circuits
Coordinate and lead onsite implementation activities with facilities partners and electricians for rack, stack, cabling, and circuit turn up activities
Configure and implement routing using BGP and OSPF, including dual ISP designs with primary and secondary behavior and traffic engineering considerations for inbound and outbound flows
Establish secure connectivity back to the data center and configure data center infrastructure to accept and route new site connections
Implement data center switching using Cisco Nexus platforms, including multi chassis port channel designs such as vPC, and validate expected failure behavior
Deploy and integrate campus and access switching, including Catalyst 9410 or equivalent, and connect access and distribution layers to WAN and core routing as required
Configure and validate wireless services using Cisco 9800 Wireless LAN Controllers, including Flex Connect and Local mode deployment patterns, access point migrations, controller discovery and join prerequisites, and guest WiFi segmentation to prevent internal access
Configure and manage firewall policy as part of site build, including provisioning firewall rules and supporting site to site IPsec VPN implementation end to end
Support load balancing activities in environments using F5, including participation in safe migration planning with testing, cutover sequencing, and rollback approach
Implement and troubleshoot multicast where required, and support voice traffic quality of service configuration, validation, and operational readiness
Execute cutovers and change activities with a strong focus on validation, troubleshooting, stakeholder communication, and minimizing user impact
Create clear build documentation, as built diagrams, configuration standards, and turnover packages for operations, including runbooks and ongoing support expectations
Partner effectively across network, security, data center, wireless, carrier, and operations teams to deliver end to end outcomes

Qualifications:

5 plus years of hands on network implementation experience supporting site builds, office expansions, or large scale campus deployments
Strong configuration experience with BGP and OSPF, including ability to clearly explain BGP best path selection, eBGP vs iBGP differences, and why OSPF Area 0 is special
Proven experience implementing dual ISP connectivity with primary and secondary failover behavior and traffic engineering for inbound and outbound routing
Data center switching experience with Cisco Nexus, including ability to explain and implement vPC and compare it to standard port channel behavior and failure modes
Experience building and troubleshooting site to site IPsec VPN tunnels end to end, including Phase 1 and Phase 2 concepts, required settings, ports, and common operational checks
Ability to provision and manage firewall rules in support of new site builds and cutovers
Wireless implementation experience with Cisco 9800 Wireless LAN Controllers, including Flex Connect vs Local mode decisioning, access point migration execution, and guest WiFi segmentation controls
Practical experience with campus and access switching, including large chassis platforms such as Catalyst 9410 or equivalent
Working knowledge of carrier connectivity considerations including handoff, routing, MTU, redundancy, demarc coordination, and circuit testing
Experience with multicast configuration in production environments
Understanding of voice traffic quality of service fundamentals and ability to implement and validate key parameters
Strong documentation skills and ability to hand over implementations into operations with clear standards and runbooks
Comfortable working onsite as needed in a flagship office or complex build environment
Nice to have experience with ACI or similar data center automation and management tooling
