About the role
The Sei Development Foundation is seeking a highly strategic and operationally adept Chief of Staff to be a direct partner to our executive director. The Chief of Staff is the ED/COO's strategic right hand - a force multiplier who keeps the organization running smoothly, ensures priorities are aligned across teams, and handles the connective tissue work that falls between functions. This is an execution and coordination role, acting as a trusted partner and core team member with broad visibility into strategic priorities, cross-functional execution, and organizational alignment. The CoS owns process, rhythm, and follow-through, while other leaders own their domains.
This position is based in New York City and requires a strong on-site presence to work closely with the executive team.
