Technical Program Manager

Position SummaryThe 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.Key ResponsibilitiesMigration Portfolio OwnershipOwn end-to-end execution of a large migration portfolio spanning data center, backbone, and edge network domains — hundreds of activities per halfManage the full migration lifecycle: scoping → dependency mapping → sequencing → hardware readiness → cutover execution → validation → decommission → close-outMaintain a single source of truth for portfolio health: site-by-site status, schedule confidence, material readiness, and risk postureDrive migration programs to completion on committed timelines while maintaining network availability throughout transitionsCutover Planning & ExecutionDesign cutover plans for live network infrastructure with zero tolerance for unplanned downtimeDefine go/no-go criteria, rollback triggers, and validation checkpoints for each migration windowSequence migrations in risk-ordered waves — lower-risk sites first, building confidence before high-complexity cutoversCoordinate execution windows across engineering (who designs the target state), operations (who executes), and vendor teams on compressed timelinesDependency & Risk ManagementMap complex cross-layer dependencies — migrations often require prerequisite work before the primary activity can proceedIdentify upstream blockers early: material shortages, design approvals, infrastructure prerequisites, and vendor deliverablesMaintain dependency matrices that connect activities across domains — backbone migrations may depend on optical planarization, which depends on cage movesProactively surface risks and mitigation plans; adjust schedules and sequences to absorb delays without cascading impactCross-Functional CoordinationDrive alignment across Network Engineering (backbone, fabric, edge, optical), Network Operations, Construction, Overlay Services, and external vendorsServe 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 platformsRun weekly program cadences, site-level execution calls, and cross-domain coordination forumsExecutive Communication & ReportingProduce clear, actionable portfolio status reporting for senior leadership — schedule progress, risk posture, material status, and decisions neededSynthesize hundreds of activities into executive-ready narratives: what's on track, what's at risk, what needs leadership attentionPresent migration health to leadership forums with confidence and clarityCommunicate schedule changes, trade-offs, and scope adjustments to stakeholders with appropriate contextContinuous ImprovementDrive process automation and tooling adoption — transform manual tracking and reporting into scalable, repeatable systems that improve migration velocity and cross-functional transparencyConduct retrospectives to capture lessons learned and improve execution playbooksIdentify opportunities to standardize migration patterns that can be repeated across sites at scaleMigration Scope: Network DomainsThe migration portfolio spans three network domains. You don't need deep expertise in all three, but you need to understand how they interact and depend on each other:Data Center Network: Platform swaps (spine and fabric switches to next-gen hardware), link speed upgrades, architecture retrofits, rack uplink restriping, facility network switch replacements (end-of-life to next-gen platforms), and management network headend builds.Backbone Network: Architecture migrations (topology standardization across sites), backbone router forklifts to next-gen platforms, optical planarization, transponder conversions (legacy to modern platforms), terminal equipment migrations, and optical cage moves that enable downstream work.Edge Network: Aggregation layer consolidation (merging switch roles), hardware forklifts retiring end-of-life equipment for next-gen platforms, next-generation backbone deployments at POPs, and IP cage migrations across multiple sites.Required Skills & QualificationsProgram LeadershipProven track record managing large, complex migration programs on live production infrastructure — you've moved or replaced systems where failure = outage, and delivered successfullyCutover planning expertise — you think in sequences, rollback points, validation gates, and blast radius; you know when to proceed and when to abortPortfolio management at scale — experience managing concurrent activities across multiple sites/regions, maintaining visibility and controlStrong dependency management — ability to map complex cross-domain relationships and sequence work to avoid cascading failuresExecutive 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 conversationsCross-functional influence without authority — coordination across engineering, operations, vendors, and construction teamsEvidence-driven and metrics-oriented — you establish KPIs, build automated reporting, and use data to drive portfolio decisions rather than relying on status theaterRisk calibration — you know what to own vs. what to escalate, and you act fast on bothTechnical BaselineFoundational understanding of data center and backbone network architecture — enough to understand why migrations have dependencies and how network layers interactFamiliarity with network migration patterns: platform swaps, hardware forklifts, link speed upgrades, optical conversions, traffic re-routingUnderstanding of migration risk: what can go wrong when you touch live production infrastructure, and what validation confirms successExperience with project management and portfolio tracking toolsIndustry Experience10+ years of program management in network infrastructure, cloud infrastructure, data center, or hyperscale environmentsDirect experience with network migrations, platform replacements, or large-scale infrastructure modernization on live production systemsExperience in hyperscale, carrier, or large enterprise environments with high-availability requirements strongly preferredEducation & CertificationsBachelor's degree in Computer Science, Engineering, Information Technology, Business, or related field (or equivalent experience)PMP, PgMP, or equivalent project management certification preferredNetwork certifications a plus, but not requiredAdditional RequirementsMust be US-basedAbility to travel up to 15% for site visits and migration supportFlexibility to support migration windows across time zones (some cutovers happen during maintenance windows off-hours)Astreya offers comprehensive benefits to all Regular, Full-Time Employees, including:Medical provided through UHC (PPO, HSA, Surest options) / Medical provided through Kaiser (HMO option only) for California employees onlyDental provided through UHCNationwide Vision provided by UHCFlexible Spending Account for Health & Dependent CarePre-Tax Account for Commuter Benefit/Parking & Transit (location-specific)Continuing Education and Professional Development via various integrated platforms, e.g. Udemy and CourseraCorporate Wellness Program provided by Goomi GroupEmployee Assistance ProgramWellness Days401k PlanBasic and Supplemental Life InsuranceShort Term & Long Term DisabilityCritical Illness, Critical Hospital, and Voluntary Accident InsuranceTuition Reimbursement (available 6 months after start date, capped)Paid Time Off (accrued and prorated, maximum of 120 hours annually)Paid HolidaysAny other statutory leaves, paid time, or other ancillary benefits required under state and federal law
