You will lead both evaluative and foundational studies in close partnership with product managers, designers, engineers, data scientists, and fellow researchers. You’ll apply qualitative and quantitative methods to understand users’ experiences, contexts, motivations, and behaviors, translating those findings into clear, actionable insights that shape roadmaps and strategies.

Leverage AI tools thoughtfully across the research workflow while applying critical review to ensure outputs are accurate. Define standards for responsible AI use in research, establishing frameworks that the broader team adopts and that position Mozilla as a leader in ethical AI-assisted research practice.

Extensive experience leading both evaluative and generative research across multiple phases of the product development lifecycle. 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). 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. 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. Recognized as an internal expert in research methodology, with the ability to introduce novel approaches, advance the field, and advise others where standard methods fall short. Collaborative and influential communicator, skilled at building partnerships with cross-functional teams and driving alignment through evidence-based insights.
