- 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, product research, or an applied research setting or similar with a strong focus on quantitative research.
- Extensive experience leading survey research across multiple phases of the product development lifecycle using quantitative insights to influence product decisions.
- Deep expertise in empirical survey methods (planning, sampling, weighting, statistical analysis) and applications (discovery, product needs prioritization, concept testing, panel surveys, intercept surveys, write-in analysis post-release measurement).
- Highly proficient in R for statistical programming and analyzing survey data.
- Extensive hands-on experience manipulating behavioral data using SQL and integrating into survey methods to tell a cohesive user-focused story.
- Demonstrated ability to craft compelling narratives using quantitative data and visualizations.
- Demonstrated success operating in fast-paced agile environments adapting to shifting priorities while maintaining research impact.
- Strong judgment balancing research depth and speed delivering insights actionable for product/business decisions.
- Hands-on experience with mixed methods and qualitative research; able to collaborate with qualitative researchers for mixed methods designs/roadmaps.
