About this team and role:

We're looking for an Executive Assistant to support the CFO and VP of Finance. This is a high-trust role at the center of Mozilla's Finance organization. You'll be the operational right hand to two senior leaders, keeping their time, priorities, and communications running smoothly while handling sensitive financial and business information with complete discretion. You'll work regularly with executive leadership (and their EAs), Board members, and external partners, so poise, judgment, and a proactive mindset matter as much as strong execution.

What you'll do:

• Act as a trusted partner and extension of the CFO and VP of Finance, providing proactive, high-level support that frees them to focus on Mozilla's most important financial and strategic priorities.


• Own complex, fast-moving calendars across both leaders: prioritize and sequence meetings, resolve conflicts, protect focus time, and align scheduling with Finance deliverables, Board cycles, and enterprise priorities.


• Run the operating rhythm of the CFO's office: plan and facilitate Finance and leadership meetings, prepare agendas and materials, capture decisions and action items, and drive follow-through.


• Prepare and refine executive-level presentations, reports, briefing materials, and correspondence for leadership meetings, business reviews, and external stakeholders.


• Coordinate domestic and international travel and manage expense reports.


• Serve as a key point of contact between the executives, their teams, and internal and external partners, ensuring timely, professional communication and follow-up.


• Support Audit committee, Investment Committee and Board preparation, including logistics, materials, and minutes as needed.


• Plan logistics for team offsites, work weeks, and events.


• Partner with other administrative colleagues on team communications, recognition moments, onboarding, and cross-team needs.


• Handle highly confidential information — financial, transactional, and personnel — with the utmost discretion.

What you'll bring:

• 7-10 years of executive administrative experience supporting one or more senior executives in a technology company or multi-location environment (calendar, travel, expenses, meeting support).


• Proven discretion and sound judgment with highly confidential and sensitive information, and comfort working closely with senior executives and Board members.


• Strong coordination and process management, with a bias toward anticipating needs and bringing options and recommendations rather than waiting for direction.


• A self-starter who thrives in a fast-paced environment, manages ambiguity and competing demands, and follows through with accuracy and attention to detail.


• Excellent written and verbal communication skills.


• Proficiency with Google Workspace.


• Familiarity with finance terminology, or experience supporting a Finance or executive team, is a plus.

What you’ll get:

• Generous performance-based bonus plans to all eligible employees - we share in our success as one team


• Rich medical, dental, and vision coverage


• Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)


• Quarterly all-company wellness days where everyone takes a pause together


• Country specific holidays plus a day off for your birthday


• One-time home office stipend


• Annual professional development budget


• Quarterly well-being stipend


• Considerable paid parental leave


• Employee referral bonus program


• Other benefits (life/AD&D, disability, EAP, etc. - varies by country)
