Core Responsibilities

Primary Functions

Plan, design, and execute moderated and unmoderated usability studies (remote and in-person), including recruitment criteria, test scripts, task design, and success metrics to measure task completion, time-on-task, errors, and user satisfaction.
Conduct heuristic evaluations and expert reviews of web and mobile interfaces against established usability principles and company-specific design patterns to identify friction and opportunity areas.
Perform accessibility audits and gap analyses against WCAG 2.1/3.0 guidelines and provide prioritized remediation recommendations to engineering and design teams to improve inclusivity and compliance.
Synthesize qualitative and quantitative research data (session recordings, surveys, analytics, heatmaps) into clear, actionable insights, design recommendations, and prioritized roadmaps for UX improvements.
Create prototypes and interactive wireframes (low- to high-fidelity) to validate design hypotheses during iterative testing cycles and to accelerate stakeholder alignment and engineering handoff.
Develop and maintain participant recruitment pipelines, screening criteria, and panels; coordinate incentives, scheduling, and logistics to ensure representative and timely test cohorts.
Design test plans, consent forms, and research protocols that meet legal, privacy, and ethical standards (GDPR, CCPA) and ensure participant safety and confidentiality.
Lead cross-functional usability workshops, co-design sessions, and design critique meetings to translate research findings into product requirements and to align teams on user-centered priorities.
Establish and track UX metrics and success KPIs (SUS scores, NPS, task success, task time) and produce executive-level dashboards and monthly reports that link usability work to product outcomes and business metrics.
Collaborate with product managers to integrate usability research into product roadmaps, define acceptance criteria informed by user behavior, and measure post-release impact of UX changes.
Work closely with engineering and QA teams to validate implementation against intended interaction patterns and to perform usability-focused regression checks for critical flows.
Mentor and train designers, product managers, and engineers in basic usability research methods, test moderation, and evidence-based decision-making to grow a UX research culture.
Maintain a centralized repository of research artifacts, recordings, insights, and recommended actions (research library) to support knowledge reuse, longitudinal studies, and internal discovery.
Facilitate A/B and multivariate tests by collaborating with data science and product teams to design experiments that validate UX hypotheses and measure user engagement and conversion lift.
Advocate for mobile, responsive, and cross-platform usability best practices, ensuring consistent interaction models across web, iOS, Android, and other touchpoints.
Partner with content strategists to identify content-related usability issues (labeling, microcopy, error messaging) and test copy variations to improve clarity and conversion.
Run cognitive walkthroughs and task flow analyses for complex, multi-step journeys (onboarding, checkout, account management) to uncover pain points and reduce drop-off.
Translate research findings into design tickets with clear acceptance criteria, annotated prototypes, and severity-based prioritization for product backlogs.
Conduct competitor and comparative usability analyses to benchmark product performance, identify industry best practices, and inform design differentiation strategies.
Prepare and present compelling research narratives, reports, and stakeholder briefings using storytelling techniques, visuals, and quantitative evidence to drive decision-making.
Manage vendor relationships for panel providers, remote testing platforms, or lab facilities and evaluate tooling to optimize research throughput and data quality.
Continuously evaluate and improve usability research methods, tooling (UserTesting, Lookback, Optimal Workshop, Hotjar, FullStory), and internal processes for efficiency and impact.

Secondary Functions

Support product analytics teams with qualitative context for quantitative anomalies and collaborate on dashboards that combine behavioral data with user feedback.
Assist with recruitment of participants for longitudinal diary studies, beta programs, and early access initiatives to capture long-term usage patterns.
Contribute to the organization's design system by documenting usability patterns, accessibility tokens, and interaction guidelines informed by research.
Provide periodic training sessions and office hours for product teams to review usability findings and co-create remediation plans.
Participate in sprint planning and agile ceremonies to ensure usability priorities are represented and that research deliverables align with development cycles.
Maintain test lab equipment, recording setups, and session templates to ensure consistent, high-quality data capture for both remote and in-person studies.
Curate and prioritize research backlogs to maximize impact on user retention, engagement, and conversion goals.
Support content and localization teams by testing localized experiences and identifying language-specific usability issues.
Track and report on usability debt, providing cost/benefit analysis for remediation of legacy UX problems.
Provide hands-on support for user onboarding optimizations and retention experiments, including prototype testing and funnel analysis.
