Technical Program Manager- Network Migrations

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.

Migration Portfolio Ownership. 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.
