Integration Program Manager

Responsibilities

• Develop, refine, and maintain the master integration plan across all 9 workstreams and 40+ sub-tracks.
• Serve as the single source of truth for program status, decisions, risks, and milestones.
• Run daily and weekly stakeholder cadences across the leadership.
• Immediately take ownership of any critical open blockers, assign owners, set deadlines, and escalate to leadership when decisions stall.
• Ensure that no workstream is unknowingly blocked by another.
• Maintain and actively manage the integration risk register.
• Monitor regulatory sequencing: FCC VoIP registration transfer, DNC VDA, SOC 2 continuity, and combined-entity sales tax setup.
• Surface compliance gaps early before they become regulatory events or customer-facing issues.
• Own the master integration timeline from now through full integration (target: H1 2027).
• Hold workstream leads accountable to milestones; escalate slippage before it compounds.
• Map and continuously update cross-workstream dependencies (e.g., the HubSpot-to-Salesforce CRM migration alone has 6 downstream dependencies).
• Cross-functionally coordinate across product, IT, legal, HR, finance, GTM, and customer success leads.
• Manage the billing/invoicing system buildout as a cross-workstream dependency touching Product, GTM, Finance, and IT.
