Administrative Assistant

The Part-Time Administrative Assistant provides reliable administrative and operational support to the Construction organization. This role will support the President of Construction and VP of Construction Operations, with the potential to support additional director-level leaders as business needs develop. The Administrative Assistant will help maintain the operating rhythm of the department by managing calendars, meetings, travel, expenses, events, onboarding logistics, organizational updates, device coordination, and other recurring business-support activities.

The role will also help preserve organizational knowledge by recognizing repeated work and finding or creating clear, usable documentation for recurring processes. This position is expected to begin at approximately 30 hours per week. The role may expand to full-time as the volume and scope of Business Support responsibilities grow; any expansion will be based on sustained demand and demonstrated organizational need.
