About the role
The Sei Development Foundation is seeking a highly strategic Chief Operating Officer. The COO is the operational ED, a seasoned executive who owns the company's day-to-day business operations, translates strategy into execution, and is accountable for the performance of core business functions. Where the ED focuses externally (fundraising, vision, key partnerships), the COO runs the internal engine, leading operations, people, finance, compliance, and is accountable for key results.
