Executive Director


San Francisco, CA




Mosaic seeks an Executive Director who is passionate about Mosaic’s mission to amplify the power of the environmental field by strengthening movement infrastructure—the connections and shared resources all social movements need to succeed. With its innovative model of participatory grantmaking, Mosaic aims to make transformative investments that build the power of the environmental field by addressing “how” positive gains are made.


Launched in 2019 as the result of a two-year design process with diverse activists and organizations, Mosaic is led by a rotating Governance Assembly of leaders from environmental, philanthropic, and justice organizations and supported by a small staff. With ideas sourced from the field, the Governance Assembly makes grants to support field-wide capacity building through leadership development, communications, shared resources, and fostering relationships within the environmental and justice communities.


The Executive Director will own initiative-wide responsibility and lead core operational functions to implement Mosaic’s innovative model. The Executive Director will work closely with the Governance Assembly to set strategy, make grants, and lead the learning and evaluation process around Mosaic’s efforts. This role will include the management of three team members with the potential for future additional direct reports.


This role requires an outcome-oriented self-starter who believes in Mosaic’s mission of engaging the entire field—from the frontlines to the “Big Greens”— to create the alignment, shared tools, and scale needed to win environmental victories during this critical decade. The role calls for a strategic and nimble professional with a deep understanding of social movements, exceptional communication, and fundraising ability.
