Responsibilities

• Own the Mission Execution operating cadence: schedule and run staff meetings, program reviews, all-hands, and skip-levels; publish agendas, capture decisions, and drive action items to closure.
• Maintain the organization's action item and commitment tracking, and chase owners until items are closed - not just logged.
• Build and maintain recurring reporting: staffing and headcount views, hiring pipeline status, OKR progress, and other metrics the leadership team runs on.
• Own the organization's documentation environment - Confluence spaces, templates, review artifacts, and record retention - so material is findable and current.
• Prepare, format, and quality-check materials for staff meetings, program reviews, and executive and customer briefings.
• Plan and execute team offsites, working sessions, conference attendance, and customer visits end to end.
• Administer purchase requests, expense reconciliation, and vendor coordination in partnership with Finance and Supply Chain.
• Coordinate onboarding logistics, space, equipment, and access for a rapidly growing organization, working across People Ops, IT, and Facilities.
• Run discrete operational projects for the SVP - process rollouts, data pulls, org communications - with limited direction.
• Handle confidential personnel, customer-proprietary, and export-controlled information with a high level of integrity and discretion.
