Technical Program Manager- Network Migrations

About The Position

The Network Migrations Senior TPM is responsible for driving hundreds of concurrent migration, retrofit, and decommissioning activities across the company’s global network infrastructure. This includes platform swaps, link speed upgrades, architecture retrofits, optical conversions, and equipment forklifts — all executed on live production networks carrying real traffic. Unlike greenfield deployments (where you're building net-new), migrations require a distinct skillset: cutover planning under zero-downtime constraints, dependency sequencing across interdependent network layers, rollback readiness, and the ability to coordinate engineering, operations, and vendor teams on tight execution windows where one wrong step creates a production outage. This is a program leadership role first. Your impact comes from your ability to influence stakeholders, drive alignment across competing priorities, and deliver outcomes at scale — all while managing the elevated risk profile inherent to modifying live production infrastructure. You'll need enough technical fluency to understand migration dependencies and unblock issues. We're looking for a senior program leader with executive presence and credibility — someone with a track record of driving complex infrastructure programs to completion in fast-paced, high-ambiguity environments.

Requirements

Proven track record managing large, complex migration programs on live production infrastructure — you've moved or replaced systems where failure = outage, and delivered successfully
Cutover planning expertise — you think in sequences, rollback points, validation gates, and blast radius; you know when to proceed and when to abort
Portfolio management at scale — experience managing concurrent activities across multiple sites/regions, maintaining visibility and control
Strong dependency management — ability to map complex cross-domain relationships and sequence work to avoid cascading failures
Executive presence and communication — ability to distill hundreds of activities into clear, compelling status, risk, and decision narratives for senior leadership; confident and credible in high-stakes conversations
Cross-functional influence without authority — coordination across engineering, operations, vendors, and construction teams
Evidence-driven and metrics-oriented — you establish KPIs, build automated reporting, and use data to drive portfolio decisions rather than relying on status theater
Risk calibration — you know what to own vs. what to escalate, and you act fast on both
Foundational understanding of data center and backbone network architecture — enough to understand why migrations have dependencies and how network layers interact
Familiarity with network migration patterns: platform swaps, hardware forklifts, link speed upgrades, optical conversions, traffic re-routing
Understanding of migration risk: what can go wrong when you touch live production infrastructure, and what validation confirms success
Experience with project management and portfolio tracking tools
10+ years of program management in network infrastructure, cloud infrastructure, data center, or hyperscale environments
Direct experience with network migrations, platform replacements, or large-scale infrastructure modernization on live production systems
Bachelor's degree in Computer Science, Engineering, Information Technology, Business, or related field (or equivalent experience)
Must be US-based
Ability to travel up to 15% for site visits and migration support
Flexibility to support migration windows across time zones (some cutovers happen during maintenance windows off-hours)

Nice To Haves

Experience in hyperscale, carrier, or large enterprise environments with high-availability requirements strongly preferred
PMP, PgMP, or equivalent project management certification preferred
Network certifications a plus, but not required

Responsibilities

Own end-to-end execution of a large migration portfolio spanning data center, backbone, and edge network domains — hundreds of activities per half
Manage the full migration lifecycle: scoping → dependency mapping → sequencing → hardware readiness → cutover execution → validation → decommission → close-out
Maintain a single source of truth for portfolio health: site-by-site status, schedule confidence, material readiness, and risk posture
Drive migration programs to completion on committed timelines while maintaining network availability throughout transitions
Design cutover plans for live network infrastructure with zero tolerance for unplanned downtime
Define go/no-go criteria, rollback triggers, and validation checkpoints for each migration window
Sequence migrations in risk-ordered waves — lower-risk sites first, building confidence before high-complexity cutovers
Coordinate execution windows across engineering (who designs the target state), operations (who executes), and vendor teams on compressed timelines
Map complex cross-layer dependencies — migrations often require prerequisite work before the primary activity can proceed
Identify upstream blockers early: material shortages, design approvals, infrastructure prerequisites, and vendor deliverables
Maintain dependency matrices that connect activities across domains — backbone migrations may depend on optical planarization, which depends on cage moves
Proactively surface risks and mitigation plans; adjust schedules and sequences to absorb delays without cascading impact
Drive alignment across Network Engineering (backbone, fabric, edge, optical), Network Operations, Construction, Overlay Services, and external vendors
Serve as the bridge between upstream engineering (who defines what gets migrated and the target architecture) and downstream execution (who physically does the work)
Coordinate with hardware supply teams on material forecasting, procurement, and delivery timing for replacement platforms
Run weekly program cadences, site-level execution calls, and cross-domain coordination forums
Produce clear, actionable portfolio status reporting for senior leadership — schedule progress, risk posture, material status, and decisions needed
Synthesize hundreds of activities into executive-ready narratives: what's on track, what's at risk, what needs leadership attention
Present migration health to leadership forums with confidence and clarity
Communicate schedule changes, trade-offs, and scope adjustments to stakeholders with appropriate context
Drive process automation and tooling adoption — transform manual tracking and reporting into scalable, repeatable systems that improve migration velocity and cross-functional transparency
Conduct retrospectives to capture lessons learned and improve execution playbooks
Identify opportunities to standardize migration patterns that can be repeated across sites at scale
