You'll also lead high-impact projects involving estate planning, trust administration, investment structuring, family relocations, insurance, and other complex matters that require strong judgment, coordination, and project leadership.

Highlights include:

• Newly created, highly visible role reporting directly to the CFO of the Family Office
• Joining a family office team of ~15 (half front office, half back office)
• Multi-billion-dollar family office serving multiple generations
• Significant ownership of tax compliance oversight and strategic family initiatives
• Opportunity to improve processes and leverage technology across the organization
• Stamford, CT office with a hybrid schedule (3–4 days per week)
• Compensation Range: $200K - $350K (Base + Bonus)
