Senior Major Gifts Officer

About Spark Spark is a science-driven, philanthropically funded non-profit that accelerates progress on unsolved climate challenges. Our goal is to enable a safer climate by filling targeted gaps in current climate actions. We look around the corner at the key blind spots that pose big climate risks or offer big climate opportunities, like major sources of unabated emissions. Then we work to speed up the development of the fields needed to address those challenges. We are a team of scientists, policy experts, innovators, and systems thinkers working to build today’s foundations for the comprehensive climate solutions we will need tomorrow. Rather than betting on individual pathways or innovations, we work to grow a field as a whole so that the most effective science and solutions can be surfaced and scaled. We use a large suite of field-building tools to support new research, markets, policies, and talent development, through both in-house initiatives and building broader coalitions. We are currently focused on super pollutants from agriculture (specifically methane and nitrous oxide), warming-induced greenhouse gas emissions, and methane removal. Spark’s impact is made possible by a community of generous and pioneering individuals, foundations, and organizations that share our vision for a safer climate future.
