About the Job

Requirements

  • 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.
  • A proven record of driving complex, cross-functional priorities from idea to execution by defining outcomes, ownership, milestones, and decision points.
  • Exceptional judgment and discretion, including handling confidential information and navigating complex executive dynamics with integrity.
  • Demonstrated ability to influence without formal authority, build trust across functions and at the most senior levels, and give direct feedback with care.
  • Outstanding written and verbal communication, with experience distilling complex information into decision-ready briefs, recommendations, presentations, and executive communications.
  • Strong analytical and strategic problem-solving skills, including framing questions, gathering information, testing assumptions, and recommending practical paths 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 track record of doing high-impact work out of the spotlight, measuring success by the CEO’s and the team’s, and acting in the best interests of the CEO and the organization.
  • A demonstrated commitment to Mozilla Foundation’s mission and to building an open, accessible, and trustworthy internet.
  • Ability to work across time zones and occasionally outside standard working hours for Board meetings, major events, or urgent organizational needs.
  • Comfort traveling for Board meetings, leadership gatherings, and major events.

Responsibilities

  • Build a strong working partnership with the CEO, align on priorities and ways of working, and clearly define the scope of delegated authority.
  • Establish trusted partnerships with each Executive Leadership Team member and learn their priorities, pressures, and ways of working.
  • Develop a deep, cross-functional understanding of the Foundation’s work and how each function connects to the CEO’s priorities.
  • Translate the CEO’s priorities into clear strategic outcomes leaders can use to guide their decisions, while maintaining a current view of changes and approaching decisions.
  • Define with the CEO what requires their attention and ensure issues reach them decision-ready, with context, options, and a recommendation.
  • Serve as the CEO’s thought partner in developing, pressure-testing, and refining strategic priorities, synthesizing executive insight and external developments to anticipate what will need to be known or decided in the next 30, 60, and 90 days.
  • Direct the CEO’s time toward strategy, external relationships, development, Board leadership, and the Foundation’s highest-consequence decisions.
  • Filter rather than forward, ensuring significant strategic shifts, material risks, major budget decisions, and Board-level matters reach the CEO early with context, options, and a recommendation.
  • Maintain a current view of the CEO’s top priorities, identify work drifting from strategic intent, and surface conflicts in priorities, resources, or attention before they become emergencies.
  • Enable the Executive Leadership Team to operate as one team around the CEO’s priorities, ensuring the right issues reach the ELT at the right level and decisions and commitments are followed through.
  • Partner with ELT members on cross-functional issues requiring CEO-level alignment but not the CEO’s direct involvement.
  • Represent the CEO’s position in internal discussions and make decisions on the CEO’s behalf within delegated authority, returning matters beyond that authority to the CEO promptly.
  • Prepare the CEO for every Board meeting, funder and partner conversation, speech, and public engagement with concise briefings, organizational context, and answers to likely questions.
  • Identify external opportunities warranting the CEO’s attention and ensure the CEO’s external commitments translate into clear internal follow-through.
  • Partner with the Foundation’s Investment Committee and its technical and strategic advisors to keep attention on the right questions, align recommendations with strategic priorities, and move decisions efficiently from evaluation to funding.

Desired Qualifications

  • Experience working across multiple legal entities, including navigating differences, building influence, and coordinating work across entities where relevant.
  • Senior roles in nonprofit, philanthropic, technology, or public-interest organizations.
  • Experience supporting or advising investment, grantmaking, or funding committees.
