As a User Research Intern, you'll join our User Research team to help researchers, designers, and product managers understand user needs across products like Coinbase Cloud and developer tools. You'll tackle complex product problems, craft research reports that drive design and product decisions, and build foundational skills in UX research at scale. What you'll do: Own one or more research projects alongside researchers, designers, and product managers to investigate a product problem or area Plan and execute research to solve complex, ambiguous product questions using appropriate methodologies Deliver research reports that clearly communicate findings and provide actionable design and product recommendations Partner with cross-functional teammates to translate user insights into thoughtful product experiences that help people engage with the crypto economy Required Skills and Experience: Actively pursuing a career in user research through a degree in a research-related field, or equivalent experience Working knowledge of general research principles (experimental design, bias, confounds) and UX research principles (usability testing, design thinking) Demonstrated ability to communicate research findings clearly, supported by a final report from a past research project (school, bootcamp, or extracurricular) uploa

Who We Are Notion is the collaborative AI workspace where teams and agents think together . We're building one place where your knowledge, projects, meetings, and AI tools live side by side, so work is faster, clearer, and less fragmented. Millions of individuals, small teams, and large companies run their work on Notion. Notinos (our employees) are customer zero in bringing this future of work to life. We care about craft, building things that last, and the belief that great work is still fundamentally human. Our goal isn’t to ship the next feature. Each and every team of Notinos is working to set the standard for how humans work together in the AI era. From building a business’s system of record to making and managing AI agents to automating away the busy work, we care deeply about giving our customers more time for their life’s work. This internship will take place from January 25 - April 16 and you will need to be able to work out of our SF office during this time. What You'll Achieve: Conduct data analyses to gain insights about Notion and use these insights to uncover opportunities for improvements in our product and business. Communicate these insights with actionable recommendations to cross-functional teams (insights are useful, impact is even better!). Work with cross-functional partners across the product and business to learn about their functions and use data to advance their respective areas. Create metrics and build dashboards to monitor the growth and health of Notion. Communicate insights and recommendations effectively to leadership and have an impact on strategic decision-making. Qualifications: Pursuing a bachelor's or master's in a quantitative field such as Economics, Statistics, Applied Math, Engineering, Computer Science, or Natural Sciences. Must graduate before December 2027. This internship will take place from January 25 - April 16 and you will need to be able to work out of our SF office during this time.
