• Build and maintain effective partnerships with commissioners, local authorities, health partners, voluntary sector organisations, and internal teams.
• Strengthen referral pathways, support co-production with people who have lived experience of homelessness, and deliver training to promote high-quality service delivery.
• Supporting engagement and client co-production activities with people who have lived experience of homelessness to inform service development.
• Deliver training and workshops to colleagues to support development in homelessness legislation, prevention strategies, safeguarding, and service delivery expectations.

Whether working independently or alongside others, you'll be motivated to make services work better and improving outcomes for the people we support.

• Proven experience leading or supporting mobilisation, implementation, setting up, improving, or developing services.
