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.
Sunrise International is a proud member of The Sunrise Project network. We adapt our role based on what is needed to have the greatest impact. We provide grants and build capacity where it’s needed, and sometimes we develop new brands or organisations and execute campaigns ourselves.
As a global network, we believe that a diversity of experiences and perspectives will help us build stronger strategies, teams, and movements. We are committed to building an inclusive and supportive workplace and encourage applications from people of diverse backgrounds, including First Nations people, people of colour, people living outside major cities, people with disabilities, neurodivergent people, and LGBTQIA+ people.

About the Program
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.
TSP International is a new and still-forming entity within The Sunrise Project network. This role requires someone who can represent the organization and the network with credibility and confidence, speak honestly and constructively to its evolving governance and mandate, and build funder confidence in its leadership and direction. The Senior Manager works in close partnership with program directors, executive leadership, and partnership members across the network to shape and lead TSP International's strategic approach to philanthropic engagement.
About The Role
The Senior Manager is a critical leadership role within TSP International, responsible for building and managing a global portfolio of highly influential philanthropic partnerships— with particular depth in European and Asian funders. This role brings sophisticated donor engagement expertise and senior-level judgment to the full range of funder-facing work, from prospect qualification through to ongoing strategic stewardship, proposal development and impact reporting, and supporting executive leadership.
Members of the Philanthropic Partnerships department across the network are self-starters who thrive in fast-paced, high-volume environments with many competing priorities across multiple departments and time zones. Successful candidates will be bursting with creative ideas, eager to master and improve the systems that underpin strong philanthropic stewardship, and able to galvanize others around shared goals. If you’re someone who likes to own projects and ongoing complex relationships and can take a spark of an idea and turn it into impact—while bringing clarity, energy, and structure to complex situations—you’ll feel right at home here.
