- All-Hands Meetings: Coordinate meeting logistics, presenter schedules, slide decks, and audience Q&A tools for company All-Hands meeting

- Recognition Programs: Administer the logistics and communications for employee recognition programs, including nomination reviews, slide updates, manager notifications, and award delivery
- Calendar Management: Maintain the internal communications editorial calendar to keep coordination and scheduling on track
- Targeted Campaign Rollouts: Project manage the execution of internal comms projects and messaging
What we're looking for:
