The Volunteer Development Manager is responsible for leading and executing council-wide strategies to recruit, onboard, train, and engage volunteers in support of Girl Scouts of Gateway Council (GSGC) programming, events, and activities. This position also oversees instructional design and content development to ensure that all volunteer learning and training resources are engaging, accessible, and aligned with council priorities. The manager spearheads the creation of flexible opportunities and meaningful engagements for short-term volunteer involvement (episodic volunteers); designs clear onramps and offramps for participation; identifies specific needs across the council; and actively recruits volunteers to fill temporary, department-specific, or project-based assignments. Partnering closely with the Volunteer Experience Director, the manager fosters a robust, inclusive, and rewarding volunteer journey for new and returning adult members. This role also develops and delivers ongoing learning and development opportunities, building an informed, energized, and mission-aligned volunteer network that directly impacts the delivery of the Girl Scout Leadership Experience.
