About The Position

PEAK6 Investments is a diversified financial services firm, and our family office team supports the principals with a broad range of financial and operational needs. We're looking for an AP & Expense Specialist who wants to truly own this function — someone who takes pride in running a clean, organized payables operation and is energized by getting the details right every time. This is a specialized, individual-contributor role with a defined and meaningful scope — and we want to be upfront about that. We're looking for someone who has found their lane, takes genuine pride in executing it well, and wants to plant roots in a role they can truly own. If you're energized by mastery over mobility, this is the right fit. You'll be embedded in the family office — which means variety, interesting work, and the occasional special project alongside your core responsibilities. The scope is stable. This role is onsite based out of our Austin, TX headquarters.
