• Generating insight through data, evidence, and internal expertise to create winning proposals.
• Researching competitors and identifying what makes Rethink Mental Illness stand out.
• Supporting successful bids through structured handovers and mobilisation.
• Contributing to continuous improvement through feedback, learning, and maintaining our Bid Library.
