Nokia SR OS Transport Engineer - Cell Site Router Conversions

LOCATION: NY / NJ Tri-State preferred; travel to cell sites and hubs as required

REPORTS TO: Program Manager, Integration

ABOUT THE ROLE

GCB integrates cell sites for Verizon on Samsung, Ericsson and Nokia equipment. This role owns the transport side of cell site router conversions to Nokia 7250 IXR routers: building the router configuration from the carrier IP plan, leading the cutover in the maintenance window, rolling back if needed, and handing off a clean, documented site. You will work alongside GCB's RAN integration engineers so router conversion and baseband integration finish in the same window.

RESPONSIBILITIES

• Build and audit Nokia SR OS router configurations from carrier IP plans and templates (interfaces, VLANs, VPRN/IES services, routing, QoS, PTP/sync)
• Write and maintain MOPs for router conversion, cutover and rollback
• Lead cutovers in the maintenance window with field crews and carrier switch teams; execute rollback inside the window when required
• Pre-check and post-check: config capture, route tables, alarms, sync status, end-to-end transport validation
• Coordinate RAN re-IP and VLAN changes with GCB integration engineers
• Troubleshoot transport faults: IP/MPLS, routing adjacencies, optics/SFPs, VLAN mismatches, PTP/timing
• Deliver as-built router configs and closeout documentation the same day as the work
• Train and mentor GCB staff pursuing Nokia NRS certification

REQUIRED

• 3+ years hands-on Nokia SR OS (7250 IXR, 7750 SR or 7705 SAR) configuration and troubleshooting
• Nokia SRC NRS II certification, or equivalent demonstrated field experience
• Live cutover experience on a carrier mobile backhaul network (cell site routers / CSR, MPLS backhaul)
• Strong IP/MPLS: OSPF/IS-IS, BGP, LDP and/or segment routing, VPRN/L3VPN, QoS
• Working knowledge of PTP (1588v2) and SyncE as used in mobile backhaul
• Able to work overnight maintenance windows and travel

PREFERRED

• Verizon cell site router conversion or CSR migration experience
• Nokia SRC NRS II / SRA / ASPE certifications
• Experience with Nokia NSP (Network Services Platform)
• Ciena SAOS exposure
• RAN familiarity (Samsung, Ericsson or Nokia basebands; eCPRI/CPRI fronthaul)
• Experience writing MOPs and rollback plans for carrier change management

SCREEN-OUT

• Cisco or Juniper only, with no Nokia SR OS hands-on time
• Enterprise LAN/WAN background with no carrier or mobile backhaul work
• Certification with no live cutover experience
