Network Implementation Engineer

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 FlexConnect
  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 FlexConnect
  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 

Tools and Technologies:

• Routing and switching: BGP,
  OSPF, VLANs, spanning tree concepts, HSRP or VRRP concepts, ACLs
• Data center: Cisco Nexus, vPC,
  port channels, common Layer 2 and Layer 3 integration patterns
• Campus and access: Cisco
  Catalyst 9410 or equivalent large chassis switching, access layer
  integration
• Wireless: Cisco 9800 Wireless
  LAN Controllers, access point discovery and join workflows, guest WiFi
  segmentation
• Security: Firewall policy
  configuration, site to site IPsec VPN, IKE and IPsec fundamentals and
  troubleshooting
• Load balancing: F5 experience
  including operational support and migration participation
• Delivery: low level design,
  bill of materials, ordering coordination, carrier circuit ordering, onsite
  coordination, cutover planning, validation, documentation, and operational
  handoff
• Documentation and
  collaboration: network diagrams, as built documentation, change management
  artifacts, and handoff packages
