The Role

Reporting to the Director, this is an exciting opportunity to lead and strengthen our fundraising strategy, ensuring sustainable growth in income to support our mission of protecting and restoring tropical forests and inspiring climate action.

3. Relationship Management and Stewardship

● Cultivate and maintain strong relationships with current and prospective corporate funders through effective stewardship and engagement.

● Work collaboratively with colleagues to deliver excellent relationship management for corporate partners.

● Work with the Communications and Marketing Manager to maximise fundraising campaigns such as the Big Give. 

4. Events and Engagement

● Lead on the planning and delivery of a flagship summer event designed to attract funders, with the aim of securing new partnerships and long-term support.

● Collaborate with colleagues to ensure the event is well-promoted, impactful, and aligned with the charity’s mission.

● Organise and attend meetings, presentations, and other events to engage with funders and promote the charity’s work. 

5. Reporting and Evaluation

● Monitor and report on fundraising income targets, maintaining accurate records of all funders and partnerships.

● Working with the relevant programmes teams, provide regular impact reports to funders, demonstrating the outcomes of their support.

● Evaluate the success of fundraising initiatives and identify areas for improvement.

6. Team Collaboration

● Work collaboratively across the team to develop funding proposals and case studies.

● Work closely with the Communications and Digital Fundraising Manager to develop online donations and regular gifts and improve the digital marketing and eNewsletter (for increasing donations). 

● Contribute to innovative fundraising campaigns and activities.

● Support and participate in wider organisational activities, including events and cross‑team initiatives as required.

● Contribute to annual budget setting and targets for fundraising.

● Line management of volunteers as required.

Safeguarding

Size of Wales, and all its staff and volunteers, are committed to ensuring a safe environment for children, young people and vulnerable adults and to prevent their physical, sexual or emotional abuse. Size of Wales is committed to acting at all times in the best interests of children and vulnerable adults, seeing these interests as paramount. Any candidate offered a job with Size of Wales will be expected to agree to and adhere to Size of Wales’ Safeguarding policy and Code of Conduct.

Equity, Diversity and Inclusion

Size of Wales is dedicated to nurturing an inclusive environment where employees can bring their full selves to work.

In 2020, we took steps to become an antiracist organisation and promote equality, diversity and inclusion. We are reviewing all our staff policies to be more inclusive.

Size of Wales is particularly keen to receive applications from people from an ethnically diverse background and disabled, deaf and neurodiverse people.  These are characteristics and identities that are currently underrepresented at Size of Wales. Furthermore, the work we do challenges modern day colonialism and discriminatory power structures that are prevalent in society and global solidarity work. Our work centres marginalised people’s voices and aims to remove barriers and increase access within the climate crisis. Having people with these identities and characteristics join the team would be invaluable and Size of Wales would become a better organisation because of this.
