Role

We are seeking an Administrative Business Partner (ABP) to serve as a strategic aide for Assemble’s senior leadership. This is a high-trust role built for someone who operates at the intersection of executive support, project management, and strategic problem-solving—and understands that flawless execution is what turns leadership’s vision into results.

At its core, this role keeps our leaders’ time, priorities, and commitments running seamlessly. The ABP proactively manages complex calendars, travel, and logistics. This role also functions as a project assistant for leadership, driving follow-ups, tracking commitments, and ensuring nothing falls through the cracks across a fast-moving portfolio. The ABP will also support or manage special projects as assigned, bringing structure and momentum to initiatives that advance the firm.

The ideal candidate is exceptionally organized and proactive—anticipating needs before they surface, spotting what leadership hasn’t yet flagged, and moving to solve it. They think strategically about the work Assemble does and how their role advances that, and carry themselves with the discretion, judgment, and polish required to represent leadership internally and externally.
