Senior Administrative Assistant

Location: New York, NY (4 days onsite, 1 day remote)

Salary: $90,000 + benefits

Full-Time

My client, a highly regarded investment and infrastructure-focused organization, is seeking a Senior Administrative Assistant to support multiple teams within their New York office. This is a high-visibility role supporting senior leaders across three distinct teams, including one larger group comprised of several combined business units.

This position will support anywhere from 6–8 individuals and, at times, up to 15 principals with varying levels of need. While the number of stakeholders may shift, the overall workload remains consistent and requires strong organization, prioritization, and the ability to seamlessly manage competing demands. The environment is fast-paced and professional, with a collaborative culture that values discretion and attention to detail.

The Senior Administrative Assistant will manage complex calendars across multiple time zones, coordinate domestic and international travel, prepare and reconcile expense reports, and serve as a key point of coordination across teams. This role requires someone who can anticipate needs, adjust quickly to shifting priorities, and provide reliable support to senior-level professionals.

The ideal candidate is proactive, highly organized, and comfortable supporting a high volume of principals with differing work styles and expectations. Strong judgment, communication skills, and the ability to operate independently are essential. Experience supporting senior leadership within finance, private equity, infrastructure, energy, or investment environments is strongly preferred.

This is a full-time opportunity based in NYC with a hybrid schedule of four days in the office and one day remote. The base salary is $90,000, along with a competitive benefits package.
