If you are a wordsmith with experience of writing clear and convincing proposals, bids and reports, we have a fantastic career opportunity for you at the WWF-UK, the world's leading independent conservation organisation. We are working to save our planet and have an ambitious growth strategy centred around maximising the vast yet mostly untapped potential of environmental philanthropy in the UK. As philanthropy impact and proposal writer you will develop and write inspirational proposals and stewardship reports to engage the philanthropy audience. Importantly, you will work closely with our philanthropy, science and conservation, and international network teams to develop detailed knowledge and understanding of the key issues, ensuring all information and content you produce is technically accurate, credible, consistent, and on-brand. Day-to-day, you will help source, organise and co-ordinate creative and engaging content, including building up a library of stats, solutions, and stories that can be used around proposals, events and specific communications. The ability to prioritise and produce quality work to deadlines will be important. You must have experience in writing high-quality proposals and reports, ideally for a high-net-value audience. Able to write persuasively and articulately, you will also possess excellent research skills.
