Major Gift Officer

Mozilla Foundation is a non-profit building a better technology future — powered by people, open by design, fueled by imagination.

We deliver people-first alternatives to today’s extractive systems. We build side by side with developers, innovators and advocates, united in the belief that a better technology future is not only possible — it’s ours to create.

The Development team at Mozilla Foundation drives the philanthropic support that fuels our mission to ensure the internet is a global public resource, open and accessible to all. The team builds meaningful relationships with individual donors, foundations, and partners who share our vision for a healthier internet. As part of a newly formed and growing team, this role plays a key part in building the Foundation’s major giving program and expanding long-term, values-aligned funding.
