The Senior Staff Mixed Methods User Researcher at Mozilla will lead complex research studies, setting the standard for research excellence and directly shaping product vision at the organizational level. This role involves driving user-centered decision-making at the executive level, influencing directors and VPs, and ensuring user needs are embedded in the long-term product and business strategy. The researcher will partner cross-functionally with product, design, engineering, data science, and marketing teams to identify high-impact research opportunities and align insights to business priorities.
Key responsibilities include integrating diverse data sources—qualitative and quantitative research, behavioral data, and market intelligence—to build cohesive, evidence-based perspectives on user experience. The researcher will leverage AI tools thoughtfully across the research workflow while applying critical review to ensure outputs are accurate. Additionally, they will define standards for responsible AI use in research, establishing frameworks that the broader team adopts and positioning Mozilla as a leader in ethical AI-assisted research practice. Elevating the research practice by setting methodological standards, identifying capability gaps across the team, and mentoring staff researchers and below is also a crucial aspect of this role.
Candidates should have 8+ years of applied research work experience, including strategic research leadership in complex organizations, with at least 6 years in the tech/SaaS industry. Extensive experience leading both evaluative and generative research across multiple phases of the product development lifecycle is required. The role demands demonstrated success operating in fast-paced, agile environments, adapting to shifting priorities while maintaining research impact. Deep expertise in qualitative methods (e.g., interviews, concept testing, usability studies) and practical experience with quantitative approaches (e.g., survey design, data analysis) are essential. Exceptional judgment in setting research priorities at the program level, making trade-offs across multiple concurrent workstreams, and advising other researchers on method, scope, and strategic framing is expected. Additionally, deep, current knowledge of AI tools used in research workflows, with the expertise to evaluate their outputs critically, define organizational standards for their use, and guide the team in applying them responsibly and effectively, is required.
