Coordinator of Big for a Day

Big Sister Boston is seeking dynamic individuals to join our Community-Based Mentoring team. The Community-Based program is a one-to-one mentoring program which matches girls, age 7-to-15, with adult women mentors. As a Big Sister staff member, you will contribute to a mentor-rich community in which every girl has access to the individual nurturing, guidance and support she needs to become a confident, competent, and caring adult.  

The Big for a Day Coordinator will manage the Big for a Day (BFAD) program where volunteers and corporate/community partners experience the power of mentoring and support a wide variety of Big Sister Boston’s programming and enrichment services. The BFAD program annually serves approximately 300 girls in the Greater Boston area, by matching them with Big for a Day Big Sisters for a one-day event. BFAD programming provides a critical service to girls who are waiting to be matched with their long-term 1:1 Big Sister mentor by giving them the opportunity to participate in enrichment programming, including STEM (science/technology/engineering/mathematics), the arts, health and fitness, college and job readiness and civic engagement. These events are most often sponsored by corporate/ community partners.  

 Big Sister is committed to hiring staff who reflect the diversity of the communities we serve. Candidates of color, multilingual and multicultural candidates are strongly encouraged to apply. If you are interested in working at a well- established, dynamic and supportive organization committed to serving girls, please apply.
