ABOUT THE ROLE We are looking for a highly analytical and research-driven Senior Researcher & Taxonomist to help us understand, categorize, and map the intricate landscape of user jobs and tasks. In this role, you will be the architect of a comprehensive taxonomy that defines the wide range of roles and careers across many domains and subdomains, along with the specific tasks required within them. You will lead both qualitative and quantitative research initiatives to uncover deep user insights and translate them into a structured, prioritized framework. If you are passionate about the Jobs-to-be-Done (JTBD) framework, comfortable leveraging cutting-edge AI research tools, and skilled at using data to rank users’ actions and behaviors, we want you on our team. This is a four-month contract with the possibility of extension. KEY RESPONSIBILITIES - Taxonomy Development: Design, build, and continuously refine a scalable taxonomy of jobs, sub-domains, distinct user tasks, tools, and data used across various job roles. - Mixed-Methods Research: Plan and execute both qualitative (interviews, observational studies) and quantitative (surveys, behavioral data analysis) user research to inform and validate the taxonomy. - AI-Moderated Research at Scale: Leverage AI-moderated user research tools to conduct, synthesize, and extract qualitative insights from large user cohorts efficiently. - Task Prioritization & Ranking: Apply basic statistical methods (e.g., MaxDiff, forced ranking, opportunity scoring, weighting, and imputation) to evaluate, rank, and prioritize tasks based on user importance, frequency, and current pain points. - Cross-Functional Collaboration: Partner with Product, Design, AI Research, Operations and Engineering to ensure the job and task taxonomy directly informs product strategy and feature development. - Insight Synthesis: Translate complex, multi-layered research data into clear, actionable frameworks, user models, and documentation. REQUIRED SKILLS & QUALIFICATIONS - Experience: 3+ years of experience in UX Research, Information Architecture, Taxonomy, Applied Economics, Human Computer Interaction or a closely related field focusing on user behavior. - Research Expertise: Proven ability to independently design and run rigorous qualitative and quantitative research studies. - Taxonomy & Frameworks: Strong understanding of classification systems, hierarchical modeling, and frameworks like Jobs-to-be-Done (JTBD).
