The successful candidate will work within the Development team & take a leading role in delivering the CSJ’s fundraising strategy.
Responsibilities include:
- Increasing the number and range of donors through prospecting, donation solicitation and the securing of new relationships, with a focus on high-net-worth individuals
- Developing and implementing strategies to secure donations from new and existing donors on a multi-year basis
- Maintaining meticulous records of all fundraising activities in a timely manner on the CSJ’s CRM database (Salesforce)
- Engaging on a regular basis with the CSJ’s policy and communications teams to remain informed of all ongoing and upcoming policy projects
- Drafting high-quality fundraising proposals, impact reports and related donor facing correspondence
- Ensuring that exceptional relationship management characterises all fundraising work and impact reporting is communicated to relevant donors
- Representing the CSJ externally and being an ambassador for its vision, mission, and values
- Supporting our Events team in delivering exceptional fundraising events from guest list formation to execution of events
