WHY THIS ROLE

The family office environment means you'll be on a small team directly supporting the principals of the business with a variety of tasks to juggle on a day-to-day basis.
We also want someone who's curious about technology - if you're the type who experiments with AI tools to work smarter and bring those ideas to the team, you'll fit right in here.
