Prospectus are thrilled to be working with an ambitious organisation transforming the landscape of modern philanthropy, in their search for an Assistant Relationship Manager to join their growing team. This fast-moving, award-winning charity is striving to make giving simpler, and the Assistant Relationship Manager will play a key supporting role in building relationships with their partners and facilitating donations and grants.

An interest in philanthropy, charities, and financial administration would be advantageous. You’ll bring enthusiasm, a willingness to learn, and the confidence to support a busy team in a fast-paced, evolving environment. Strong communication skills and an interest in developing relationship-building skills are important.

If you’re motivated by problem solving, enjoy working with detail and developing your understanding of complex information, and want to see the tangible social impact of your work, this could be the role for you.

What You’ll Do:

• Support the development and maintenance of relationships with clients, donors, and intermediaries
• Assist with financial administration, including reconciliations, payment processing, and budgeting support
• Help review and summarise grant applications and project reports with accuracy
  Support due diligence processes in line with UK charitable law and regulatory requirements
• Work with complex information, helping to identify key points and flag risks where appropriate
• Maintain internal processes and systems, ensuring accuracy while adapting to a dynamic, entrepreneurial environment
• Support external communications, help develop impact materials, and assist at events
