Core Responsibilities

Primary Functions

Plan, design and execute end-to-end usability research programs (moderated lab testing, remote unmoderated studies, guerrilla testing) to evaluate new features, prototypes, and existing product flows; produce clear research plans, recruitment criteria, scripts, and test tasks aligned to product hypotheses and KPIs.
Conduct moderated usability sessions and workshops (in-person and remote), facilitating participants through task scenarios, ensuring validity and consistency of data collection while probing to uncover unmet needs and mental models.
Run unmoderated usability tests and surveys at scale using tools such as UserTesting, Lookback, Maze or similar platforms, and interpret both qualitative feedback and quantitative success metrics to prioritize recommendations.
Design and develop low- and high-fidelity prototypes (wireframes to interactive mockups) for usability validation using Figma, Sketch, Axure, or InVision; iterate on designs based on test results and stakeholder feedback.
Synthesize qualitative findings into pragmatic, data-driven recommendations and artifacts (insight reports, usability findings decks, prioritized UX backlog items, personas, journey maps) for product and engineering teams to implement.
Define and track UX success metrics and KPIs (task completion rate, time-on-task, error rate, SUS/NPS, CSAT, conversion funnels) and present impact analysis that ties usability improvements to business outcomes.
Collaborate with product managers to translate usability insights into product requirements, user stories, acceptance criteria, and roadmap priorities using a clear, hypothesis-driven approach.
Partner with engineers and QA to ensure usability recommendations are implemented accurately, perform post-release validation testing, and measure the before/after impact on UX metrics.
Operate as the usability and accessibility subject-matter expert: apply heuristics evaluations (Nielsen, ISO) and WCAG 2.1 guidelines to review UI for compliance, provide remediation guidance, and work with engineering to ensure accessible implementations.
Use quantitative analytics (Google Analytics, Mixpanel, Heap), session replay (FullStory, Hotjar), and A/B testing platforms (Optimizely, VWO) to augment qualitative research, identify friction points and conversion drop-offs, and validate design decisions.
Facilitate cross-functional discovery workshops, design sprints, co-creation sessions, and stakeholder interviews to align teams on user problems, success criteria, and usable solutions.
Create and maintain user personas, mental models, task flows, and customer journey maps that inform product strategy, design decisions, and prioritization of usability improvements.
Develop and maintain a prioritized usability backlog and roadmap, balancing quick wins and strategic investments; communicate trade-offs and ROI to senior stakeholders to secure investment in UX work.
Lead longitudinal usability studies and longitudinal diary studies to observe behavior over time, identify retention and engagement drivers, and inform product lifecycle decisions.
Manage recruitment, screen participants for usability studies, and coordinate logistics for lab sessions or remote tests; ensure representative sampling to improve generalizability of findings.
Run heuristic evaluations and expert reviews to quickly identify areas of high usability risk and propose pragmatic remediation strategies for iterative delivery.
Translate user research findings into clear, implementable design patterns, interaction guidelines, and microcopy suggestions (UX writing) that reduce cognitive load and increase trust.
Mentor designers, product owners, and junior researchers on usability best practices, research methods, effective moderation techniques, and how to interpret and apply results to product decisions.
Document research repositories and playbooks, maintain an organized library of recordings, transcripts, and insight summaries to enable knowledge transfer across teams and prevent duplicated research.
Coordinate with legal, privacy, and security teams to ensure participant data handling and research activities are GDPR/CCPA compliant and maintain participant confidentiality.
Identify opportunities for experimentation (A/B tests, multi-armed bandit tests) to validate usability hypotheses, design experiments, analyze outcomes, and recommend rollouts based on statistical significance and practical impact.
Support product launches and feature releases by conducting pre-launch usability validations and defining acceptance criteria tied to baseline UX metrics and performance thresholds.
Communicate complex research findings to executives and business stakeholders using compelling storytelling, visualizations, and clear recommendations that drive decision-making and prioritization.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Provide training and internal workshops to embed user-centered design and usability practices across product and engineering teams.
Maintain relationships with external vendors and usability labs, negotiating contracts and ensuring high-quality research delivery.
