• Proven ability to successfully lead and ship complex software projects
• Experience in Rust
• Familiarity with one of the following front-end technologies: JavaScript or React
• Experience with telemetry, privacy-preserving analytics, and/or programmatic advertising is a plus.

• Commitment to our values:
• Welcoming differences
• Being relationship-minded
• Practicing responsible participation
• Having grit

What you’ll get:

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

About this team and role:

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. 

What you’ll do: 

• 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.
• Design & Engineering Partnership: Co-create user-first ad experiences and performant services (decisioning, delivery, measurement) that meet strict latency, quality, and accessibility standards. Provide clear problem framing and success criteria; give actionable design and technical feedback that raises product quality and delivery velocity.
• Business Development: Partner with BD/Sales to shape deal structures and launch new supply and demand integrations (e.g., PMP, SSP/DSP, measurement). 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. 

What you’ll bring: 

• 10+ years in product management or (adjacent technical roles) including 5+ years building performance advertising products at meaningful scale.
• Demonstrated end-to-end ownership of technical products from concept to launch to iteration-with clear business and reliability outcomes.
• Experience in two-sided marketplaces (bidding, ranking, pacing, measurement).
• Working proficiency with data and experimentation (SQL, dashboards, A/B testing design, interpreting causal and observational results).
• Track record of influencing across multiple teams (Engineering, Research, Data, Security/Privacy, GTM) without direct authority.
• Exceptional written communication: PRDs, decision documents, and executive level narrative storytelling.
• Commitment to our values:
• Welcoming differences
• Being relationship-minded
• Practicing responsible participation
• Having grit

What sets you apart: 

• Experience working with content/surface teams on ad format design and layout.
• Comfortable operating in ambiguous 0-1 environments and scaling successful bets from 1-n.
• Passion for ads monetization, privacy, and user agency.
• Strong technical fluency with ML systems (training vs. inference, feature engineering, evaluations, drift, model/version management) and modern cloud/data stacks.

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
