What the job involves
- Mozilla Ads is building privacy-forward advertising that funds an open, people-first internet. We are looking for a Senior Product Manager, Advertising Products (individual contributor) to help lead the development of Mozilla’s next generation advertising infrastructure
- This infrastructure will power multiple performance ad placements across search and display - think real-time decisioning, partner integration, privacy-preserving personalization, and reliability at scale
- Product Vision & Strategy: Drive the vision, strategy, and execution for our privacy-preserving advertising products (e.g., targeting, search suggestion monetization, ad formats)
- Innovative Solutions: Drive rapid hypothesis testing and experiment-led product development to improve ad relevance, user experience, and advertiser ROI-while preserving privacy
- Cross-Functional Collaboration: Orchestrate execution across Ads Engineering, Data Science, Firefox Platform, Design, Legal/Policy, Trust & Safety, Finance, and GTM. Convert strategy into crisp product requirements and cross-team plans

Define product terms, API/SDK requirements and success metrics: influence pricing and packaging; steward marquee partnerships from tech evaluation through scaled adoption
- Data-Driven Decisions: Establish the experimentation and measurement backbone for Ads (instrumentation, event quality, dashboards). Set and track KPIs such as RPM/eCPM, CTR, fill rate, viewability, latency SLOs, advertiser retention, and user sentiment/trust signals. Use privacy-preserving analytics to guide roadmap bets and protect the user experience with guardrails
- Effective Communication: Deliver exec-ready narratives, PRDs, and decision memos that clarify trade-offs and drive alignment. Represent Ads strategy and results to Mozilla leadership, cross-functional partners, and external stakeholders; set a strong operating cadence for multi-team programs
- Industry Awareness: Anticipate and respond to platform and regulatory shifts (e.g., cookie deprecation, privacy standards, ATT, IAB specs). Continuously translate market and ecosystem signals into strategy, ensuring Mozilla leads on privacy-preserving advertising
- Thought Leadership: Champion Mozilla’s point of view on trustworthy, user-respecting ads and open standards. Influence industry forums and standards, publish insights, and build relationships that elevate Mozilla’s role in the ecosystem
Our take
Mozilla develops a range of free and open-source software, with its most familiar product being Firefox. Operated with a mission-driven, not0for-profit ethos, Mozilla champions online privacy, open standards and user-choice.
Beyond Firefox, Mozilla has focused on privacy forward offerings such as Mozilla VPN, which allows users to browse securely without being tracked. The company has also streamlined its product portfolio to concentrate on initiatives that align closely with its core mission, ensuring resources are dedicated to improving user experiences while fostering safer, more open digital environments.
Alongside this, its impact extends into the developer and tech community, having played a pivotal role in the creation of Rust, a systems programming language celebrated for its speed and efficiency. With a loyal user base, ongoing innovation, and a clear commitment to privacy and open-source principles, Mozilla remains an influential player in the technology landscape.

Company benefits
- Health and wellness: Mozilla covers medical, dental and vision plan premiums at 100% for U.S. and Canadian employees. Our offerings give you the options you need to manage your health — and your family’s — the way you want.
- Mental health: Mental health is as important as our physical health. That’s why Mozilla’s health benefits include therapy and coaching sessions to make sure our people have access to the care they need.
- Time away: With all of life’s demands, time away from work to disconnect and recharge is essential. In addition to country-specific holidays (12 in the U.S. and Canada), vacation and sick time start accruing right away (specifics vary by country). Everyone also takes a pause together on quarterly all-company wellness days, plus you get to celebrate the most personal holiday of all: your birthday.
- Parental leave: While Mozilla’s parental leave policies vary globally, our U.S. and Canadian-based employees can look forward to 26 weeks of paid leave for childbearing parents and 12 weeks of paid leave for non-childbearing parents.
- Financial: Mozilla is a private company, so our compensation isn’t tied to stock options or equity plans. Instead, we offer generous, performance-based bonus plans to all regular employees to underscore that we share in our success as one team. As for retirement savings for US and Canadian employees, Mozilla contributes a percentage of your eligible base salary each year to the 401(k) Plan/RRSP (regardless of whether you contribute or not), with 100% vesting.
- Learning and development: We’re big believers in learning by doing, and we also want to invest in your education and development beyond your role. Every employee is eligible for an annual professional development budget. Mozillians can put it toward technical or management training, certifications, conferences and more.
- Help when you need it: Life is full of surprises; that’s why it’s important to be prepared. Mozilla provides Life/AD&D and Short and Long Term Disability insurance (offerings may vary by locale) to ensure that you and your family will have a safety net in place should you ever need it.
- Plus a bit more: A few other benefits include a quarterly wellbeing stipend (to use on those things just for you), an employee referral bonus, internet reimbursement if you’re remote, and a budget for office essentials to make working remotely ergonomically comfortable.
