About Us

The Sunrise Project is a global network of independent organizations united by a common mission: drive interventions to accelerate the transition from fossil fuels to renewable energy. We developed a unique model of changemaking where we identify key leverage points, design strategic interventions, and organise diverse networks to make them happen.

About the Program and Role

As Sunrise International’s Senior Manager, you will be working in close strategic alignment with the global philanthropy function, the dynamic engine behind mobilizing financial resources to power strategic interventions across the global climate justice movement. Together, we act as the “connective tissue” between The Sunrise Project network of entities and our philanthropic partners, ensuring that our partners are inspired, valued, and deeply engaged collaborators. With a focus on high-impact stewardship, creative collaboration, and strategic storytelling, our goal is to build a resilient and diverse funding base for the strategic interventions of the climate justice movement when the Sunrise network can make a difference. This is an exciting moment to join a growing function at a global philanthropy working at the intersection of justice, climate, and clean energy.

Key Responsibilities

• Guide program directors and partnerships staff on how to represent TSP International accurately and compellingly in funder-facing materials, consistent with the entity's distinct identity and mandate
• Provide mentorship, editing, proofreading, and submission support to teams across the network

• Demonstrated experience with giving and receiving feedback at all levels of an organization
• Comfortable operating in an emergent organizational context where priorities shift and sound judgment about what to prioritize and how to communicate deprioritized work is essential
