Job description

We are a private single-family office based in Englewood, New Jersey. Our office supports both the personal and household administrative needs of the family and the operations of a small in-house investment group focused on long-term portfolio strategy.

This is a small, discreet, and high-trust environment where professionalism, judgment, and attention to detail matter. We are looking for someone experienced, reliable, easy to work with, and comfortable working closely with principals and advisors in a private office setting.

About the Role

We are seeking a part-time, hourly Administrative Assistant to provide approximately 18 hours per week of on-site support (~6 hours, 3 days per week). The role is expected to be roughly split between family/household administrative support and investment office support.

This position is well suited for an experienced administrative or executive assistant who enjoys variety, values flexibility, and is looking for steady part-time work rather than a full-time role. The ideal candidate will have some past experience as an administrative assistant at an investment firm or related financial services firm.

What You'll Do

• Provide comprehensive administrative support including managing calendars, scheduling, travel arrangements, and household logistics.
• Coordinate with vendors, service providers, attorneys, accountants, and outside professionals.
• Assist with errands, correspondence, reservations, and day-to-day administrative needs.
• Track expenses, process invoices, and assist with light bookkeeping.
• Help maintain orderly systems for both family office and investment office workflows.
• Handle sensitive information with discretion and sound judgment.

What We're Looking For

• 5+ years of administrative assistant, executive assistant, or office support experience.
• Prior experience in a financial services firm, family office, RIA, hedge fund, private equity firm, or similar environment preferred.
• Exceptional discretion, confidentiality, and professionalism.
• Strong organizational skills and careful attention to detail.
• Proficiency with Microsoft Office and calendar/email tools.
• Comfort working independently in a small-office environment.
• Clear written and verbal communication skills.
• Ability to manage both personal/household and business/investment-related tasks.
