Office Manager

Job Description

Job Description

Position Summary

The Office Manager is a newly created role at the holding company level, supporting the President of AEG and its operating entities. This position is central to modernizing how the organization works: leading the transition from a paper-based office to a digital one built on Microsoft 365, supporting the rollout of BQE Core for project management and accounting, and standing up an organized electronic filing system across all three entities.

The Office Manager will consolidate and elevate responsibilities currently split across two administrative positions and will own the core administrative infrastructure of the company, including certifications and licensing, proposal and project setup, document and template libraries, onboarding, and vendor management. This role supervises administrative support staff, coordinates with NPN’s current office manager for knowledge transfer, and works closely with project management, leadership, accounting, and IT. It is a highly visible, forward-facing role that requires strong judgment, polish, and the ability to build trust quickly with staff, clients, and vendors alike.
