Strategy Development Manager Jobs in Morristown, NJ

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.

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 the Communications & Strategy Consultant on positioning, narrative, and editorial direction, moving proposals through a structured review process.
