The Center for Science in the Public Interest (CSPI) seeks a strategic and relationship-driven Senior Development Officer to lead cultivation, solicitation, and stewardship of private foundations, family foundations, state-based foundations, and other institutional funders. The person in this leadership role will build and manage a portfolio of foundation prospects and donors, develop compelling funding proposals aligned with CSPI's programmatic priorities, and work in close partnership with the Senior Development Director, who oversees CSPI's foundation fundraising program as a whole, to advance a coordinated, growing pipeline of institutional support.

This is an excellent opportunity for an experienced fundraiser with expertise in foundation fundraising and a commitment to CSPI’s mission to improve health and well-being for people in communities, regardless of race, income, education, or social factors. The successful candidate will help expand CSPI’s institutional funding base at a pivotal moment for food safety, nutrition and health policy, with potential for growth into an advanced role as CSPI’s development program evolves.

The Senior Development Officer is part of a five-person Development Department and reports directly to the Senior Development Director. This role works closely with executive leadership, finance, grants management, and program staff across the organization to align fundraising strategy, donor stewardship, grant compliance, and organizational priorities. The ideal candidate is a skilled relationship builder and project manager who can connect the dots across teams.

Our staff outside of the D.C. area work remotely at locations across the U.S. We will consider DC-based or remote applicants within the U.S. for this position.
