Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people. The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

The Firefox User Research team champions human-centered exploration of complex problems, using evidence, data, and insight to drive decision-making. We use quantitative and qualitative research to understand business needs and uncover user insights that inform product and design strategy. As a Senior Staff Quantitative User Researcher, you’ll lead both strategic and tactical quantitative studies in close partnership with product managers, designers, engineers, marketers, data scientists, and fellow researchers. You’ll apply quantitative methods to scientifically understand users’ experiences, needs, motivations, and behaviors at scale, translating those findings into clear, actionable insights that shape roadmaps and strategies.

What you’ll do:

  • Own strategic quantitative research initiatives from scoping business needs and designing surveys to synthesizing data and communicating actionable recommendations to influence product decisions.
  • Utilize a variety of research methods to embed quantitative insights into the end-to-end product development lifecycle (e.g., discovery opportunity sizing, prioritization, concept testing, tracking and measurement after launch).
  • Partner cross-functionally at a strategic level with product, design, engineering, data science, and marketing to develop and own a research roadmap, identify high-impact research opportunities, and align insights to business priorities.
  • Analyze and translate complex data sources (e.g., surveys, behavioral data, and market intelligence) to build cohesive, evidence-based perspectives that guide product decisions.
  • Champion user-centered decision-making by embedding research into product strategy, advocating for user needs, and influencing leaders across functions.
  • Elevate the quantitative practice by mentoring peers, refining methods and tools, and scaling approaches that increase the visibility and impact of user insights across Firefox.

What you’ll bring:

  • 8+ years of experience in user research,...
