Full Job Description

OVERVIEW

This is a full-time, on-site role supporting both the Principal and the President of an active single-family office. Serving as a trusted partner to both leaders, you will manage executive support, office operations, financial administration, and personal logistics across a diverse portfolio of business interests, philanthropic activities, residential properties, and personal affairs.

You will work closely with the family office team to ensure the smooth day-to-day operation of the office while providing high-touch executive and personal support. The role spans both professional and personal domains and requires someone who is highly organized, proactive, discreet, and comfortable operating in a dynamic environment where priorities shift and no two days look the same.

The right candidate is exceptionally organized, proactive, and discreet—someone who takes ownership of the details, anticipates needs before they arise, and is energized by variety and a genuinely hands-on role. This is an in-person position; a meaningful part of the work involves being physically present in the office to handle on-site needs.

RESPONSIBILITIES

Executive & Business Support

Oversee executive support across the principal’s personal and professional activities
Train and develop the team member responsible for calendar, scheduling, travel, and administrative coordination
Ensure meetings, correspondence, follow-up, board activities, and key commitments are managed proactively
Oversee personal and business travel planning and related logistics
Serve as backup for calendar, travel, and executive support as needed
Ensure expenses, records, files, and contact lists are accurate and organized
Improve executive support processes and systems

Project Management

Manage special projects from start to finish—coordinating vendors, timelines, budgets and documentation (e.g., asset sales, property projects, and other one-off initiatives)
Support the rollout of new office systems, tools, and technology (including accounting and AI tools) in partnership with the head of the family office
Develop, document, and maintain office standard operating procedures and the family office operating manual
Support party planning and event logistics

Financial Operations

Own the bill-pay function: document, classify, and pay invoices, and track refunds
Manage payroll (with approval from the head of the family office)
Prepare the annual budget
Manage petty cash—refill, reconcile transactions, and provide periodic reports
Manage property tax payments and maintain property-related deduction logs
Prepare and process transactions, wires, and capital calls through the family’s financial institutions (with approval from the head of the family office)
Liaise with outside financial partners and advisors

On-Site & Office Management

Run errands and handle day-to-day on-site office needs
Manage filing and storage systems
Support household staff scheduling and maintain master schedules
Manage office payroll
Assist with HR processes, including onboarding, offer letters, and enrollment
Provide light IT support and oversee external IT partner

Property Administration

Serve as a primary point of contact for contractors, service providers, and property-related projects
Maintain operational records across residential properties
Manage record-keeping and renewals for home, auto, and boat insurance policies
Maintain records and appraisals for artwork and other valuable assets
Liaise with insurance representatives and process updates and reporting as needed
Coordinate vehicle maintenance, registration, and related logistics

CANDIDATE PROFILE

5+ years as an executive assistant, personal assistant, or in a comparable high-trust support role, ideally supporting a senior principal or executive
Comfortable operating across both professional and personal domains
Strong financial and bookkeeping acumen—comfortable owning bill pay, payroll, budgeting, and financial record-keeping
Exceptionally organized, detail-oriented, and reliable, with strong follow-through
Proactive and resourceful—anticipates needs and takes ownership of the details
Discreet, trustworthy, and able to handle sensitive matters with the utmost confidentiality
Strong communicator, comfortable engaging with vendors, advisors, and senior contacts
Able to work on-site full-time and handle hands-on, in-person office duties
Technically fluent and comfortable using modern tools (including AI) to work efficiently
Calm under pressure, flexible, and able to juggle competing priorities with good judgment
