T-Mobile's VIC (Voice, Interconnection & Contract Compliance) team is responsible for sourcing and managing the commercial relationships that power the nation's largest and fastest 5G network. As a Technology Sourcing Manager on the Network Backhaul team, you will own the end-to-end procurement of transport circuits connecting T-Mobile's cell sites, macro towers, and small cells to our core network — and the long-haul and metro circuits that interconnect our core infrastructure across the country.
You will build and maintain strategic supplier relationships across a large and diverse ecosystem of national carriers, regional fiber providers, cable MSOs, satellite operators, and subsea cable partners. You will negotiate and execute all commercial terms, drive competitive sourcing events, and partner closely with network engineering and transport planning teams to translate complex technical requirements into commercial outcomes that balance cost, speed to deploy, and network resiliency.

This role procures the following circuit and service types in support of T-Mobile's Cell Site and Core Network connectivity:
• Dedicated Internet Access (DIA) — symmetric, SLA-backed broadband circuits for cell site and small cell backhaul
• Carrier Ethernet / Ethernet over Fiber (EoF) — MEF CE 2.0 E-Line, E-LAN, and E-Tree services from 1G to 100G+ for cell site, aggregation, and metro core
• Wavelength Services (DWDM / CWDM) — lit and dark wavelength capacity for high-bandwidth, low-latency Core-to-Core and data center interconnect
• Dark Fiber (IRU / Term Lease) — Fiber-to-the-Tower (FTTT) and metro ring infrastructure via indefeasible right of use or term lease agreements
• MPLS / IP-VPN — Layer 2/3 managed WAN services for network aggregation and hub-site connectivity
• Satellite Backhaul — LEO (Starlink/OneWeb) and GEO satellite services for rural, remote, and hard-to-reach cell sites where fiber is unavailable or cost-prohibitive
• Subsea / Submarine Cable Capacity — international and island-market core connectivity (Hawaii, Puerto Rico, and beyond)
• Fixed Wireless / Microwave (PtP / PtMP) — licensed microwave and millimeter-wave links for rapid deployment, rural coverage, and emergency restoration

Job Responsibilities:

• Competitively source backhaul circuit spend through RFP, RFI, and RFQ processes, spanning the full category scope above across national and regional supplier portfolios

• Draft, negotiate, and execute contractual documents including Master Service Agreements (MSAs), service orders, IRU agreements, dark fiber leases, letter agreements, and purchase orders for high-volume circuit procurement

• Drive sourcing strategies for large-scale, high-volume circuit deployments (1G / 10G / 100G+), balancing total cost of ownership (TCO), speed to deploy, and network resiliency

• Develop and apply financial models comparing lit service vs. dark fiber IRU trade-offs, including NPV, CapEx/OpEx analysis, and long-term cost projections

• Manage a portfolio of 50+ national and regional telecom suppliers through scorecard development, performance management, and quarterly business reviews (QBRs)

• Liaise with network engineering, transport planning, and operations teams to interpret technical specifications — route diversity, latency thresholds, SDI requirements, SRLG constraints — into commercial and financial outcomes

• Lead supplier escalations related to service delivery intervals (SDIs), FOC date jeopardies, outage events, SLA breaches, and billing disputes

• Prepare and present business cases, sourcing strategies, and supplier recommendations for executive review and approval

• Conduct risk assessments across the supplier base, identifying single-source dependencies, geographic concentration risks, and financial viability concerns

• Support sourcing plan management, project status reporting, and supplier issue tracking across nationwide network deployment programs

Education and Work Experience:

• Bachelor's Degree plus 5 years of related experience OR Advanced degree with 3 years of related experience (Required)
