Program Development Manager Jobs in Levittown, NY

Development Manager The Horticultural Society of New York ("The Hort") seeks an organized, collaborative, and energetic Development Manager to run its foundation grants and giving program. This is a redesigned role for a development professional who writes well, manages deadlines reliably, and responsibly uses AI tools to do the work faster and better. The Development Manager drafts foundation proposals, supports government grant applications, and prepares individual giving appeals, working with the Hort's AI tools and system and The Hort's Communications & Strategy Consultant.

The mission of The Horticultural Society of New York is to improve human lives through horticulture. We bring plants into the places where daily life happens, especially in neighborhoods with the least access to green spaces. We turn "unplantable" urban spaces-sidewalks, medians, traffic triangles, and streets-into gardens and plantings that last.

We engage communities through learning, wellness, and paid work, so the benefits of plants are more accessible to New Yorkers across our city. Responsibilities: Proposal & Appeal Development Draft foundation proposals, individual giving appeals, and impact reports, and support government grant applications, combining your own writing with The Hort's AI tools and systems. Work with program managers to gather the program design, metrics, and outcomes that proposals require, and support program staff in shaping logic models and outcome measures where needed.

Work with the Communications & Strategy Consultant on positioning, narrative, and editorial direction, moving proposals through a structured review process. Use AI tools to support research, first drafts, budget narratives, and reporting, while bringing the judgment and organizational knowledge the tools can't supply. Keep voice, factual accuracy, and funder-guideline compliance consistent across submissions.

Funder Relationships & Stewardship Manage relationships with The Hort's established foundation funders, keeping each one informed, appreciated, and well served. Coordinate site visits, tours, and touchpoints for funders, prospects, and board members, working with senior leadership. Draft tailored acknowledgments, updates, and stewardship communications that keep funders close over time.

Serve as primary administrator of DonorPerfect, The Hort's fundraising database, including oversight of gift processing, preparation of donation reports, reconciliation of contributions, and maintenance of accurate, current donor records. Prospect Research & Pipeline Identify new foundation and corporate funding opportunities that fit The Hort's programs. Build and maintain a clear, prioritized prospect pipeline.

Grants Management & Compliance Own and maintain an accurate grants calendar, with timely submissions, renewals, and reports. Track deliverables and metrics commitments across active grants, coordinating with program staff for on-time, compliant reporting. Manage grants from application through reporting and close-out.

Program & Budget Partnership Work with the Finance team and program staff to build grant budgets and budget narratives. Take part in the annual budgeting process, helping match grants and giving opportunities to funding gaps.
