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

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!

Our CEO is increasingly focused outward on the Board, funders, partners, and public conversations that will shape the Foundation’s next chapter. This newly created Chief of Staff role exists to extend the CEO’s reach inside the organization and make that outward focus possible.

Reporting directly to the CEO, you’ll serve as the CEO’s strategic partner, internal proxy and trusted extension of their leadership. You’ll also partner with the Foundation’s Investment Committee and its technical and strategic advisors, keeping their focus on the right questions, their recommendations aligned with the Foundation’s strategic priorities, and decisions moving efficiently from evaluation to funding.

Building a solid working partnership with the CEO, aligning on priorities, ways of working and clearly defining the scope of your delegated authority.

Developing a deep, cross-functional understanding of the Foundation’s work and how each function connects to the CEO’s priorities.

Getting up to speed with the Investment Committee and its advisors, and helping keep their focus on the right questions so decisions move efficiently from evaluation to funding.

As the Chief of Staff to Mozilla Foundation’s CEO, you will…

Direct the CEO’s time toward strategy, external relationships, development, Board leadership and the Foundation’s highest-consequence decisions.

Filter rather than forward, so significant shifts in strategy, material risks, major budget decisions and Board-level matters reach the CEO early, with context, options and a recommendation.

Ensure the CEO enters every Board meeting, funder and partner conversation, speech and public engagement fully prepared, with concise briefings, organizational context and answers to likely questions.





Steward alignment between the Investment Committee’s work and the Foundation’s strategy: keep its technical and strategic advisors focused on the right questions, surface gaps, risks or competing views, and bring forward matters that need the CEO’s judgment.

The Chief of Staff does not manage the Executive Leadership Team or run the Foundation’s operations. This role does not have any direct reports and also doesn’t manage the CEO’s calendar, scheduling or administrative support.

Significant, verifiable experience as a strategic partner at CEO or executive-team level, with a track record of leading high-stakes work and turning ambiguity into structure and action.

Experience working across multiple legal entities is a plus, including navigating differences, building influence, and coordinating work across entities where relevant.

Demonstrated ability to influence without formal authority, build trust across functions and at the most senior levels, and give direct feedback with care.

Strong analytical and strategic problem-solving skills: you frame the right question, gather the right information, test assumptions and recommend a practical path forward.

Disciplined prioritization, with the agility to move between long-term priorities and time-sensitive issues without losing the thread.

Direct experience supporting Board governance, fundraising or other high-stakes external relationships at an executive level.

A demonstrated commitment to Mozilla Foundation’s mission and to building an open, accessible and trustworthy internet.

The ability to work across time zones and occasionally outside standard working hours for Board meetings, major events or urgent organizational needs.





Comfortable traveling for Board meetings, leadership gatherings and major events.

Senior roles in nonprofit, philanthropic, technology or public-interest organizations.

A few things that are true about how we work at Mozilla Foundation. Stay curious and current :you stay close to what executives are seeing and what’s happening in our fields and communities, and turn it into the context the CEO needs. Flex with purpose : you move between long-term priorities and time-sensitive issues as context shifts, and adapt how you work with each executive. Lead with care :you hold a high bar for the work while treating people as whole humans. Mozilla Foundation is dedicated to fair and equitable compensation for our staff. We aim to pay a competitive and market-based salary based on the responsibilities and requirements of the role. We do not ask for, or take into account, salary histories in our offer process.
