Core Responsibilities

Primary Functions

Lead the end‑to‑end planning, design, moderation and analysis of complex usability studies (lab, remote moderated, unmoderated, mobile and prototype testing) to validate product concepts, measure task success, and reduce user friction across digital experiences.
Define and implement a cross‑product usability research strategy and roadmap aligned to business objectives, product milestones, and customer outcomes, ensuring research priorities drive measurable UX improvements.
Design rigorous mixed‑methods research programs combining qualitative approaches (contextual inquiry, ethnography, usability testing, diary studies) with quantitative methods (metrics analysis, A/B testing, funnel analysis) to create a holistic view of user behavior.
Conduct heuristic evaluations, cognitive walkthroughs, and accessibility audits (WCAG 2.1/3.0) to identify usability and compliance gaps and provide prioritized remediation plans for design and engineering teams.
Translate usability findings into actionable product requirements, user stories, and acceptance criteria; partner with product managers and engineers to ensure research insights are implemented and validated.
Establish and track UX success metrics (task completion, time on task, SUS, NPS, CSAT, retention, conversion) and present trend reports to executive leadership to quantify the impact of design changes.
Prototype and validate interaction designs using low‑ and high‑fidelity prototypes (paper, HTML, Figma, Axure) to iterate on concepts quickly and de‑risk product decisions before development.
Lead or support large‑scale A/B experiments by defining hypotheses from usability insights, advising on experimental design, and interpreting results to inform product decisions.
Manage research operations including participant recruitment, panel management, vendor selection (e.g., UserTesting, Lookback, Optimal Workshop), budgeting, and ethical/privacy compliance for user studies.
Synthesize complex qualitative data into compelling narratives, customer journey maps, personas, and evidence‑based recommendations that are easily consumable for cross‑functional stakeholders.
Mentor and coach UX researchers and designers on best practices for usability testing, research synthesis, storytelling, and stakeholder influence to raise overall team capability.
Provide subject matter expertise on accessibility, inclusive design, and internationalization to ensure products meet regulatory requirements and offer equitable experiences for diverse users.
Collaborate with analytics and data science teams to link qualitative usability insights with quantitative product telemetry (GA, Mixpanel, FullStory) for deeper diagnosis and root cause analysis.
Facilitate cross‑functional workshops (story mapping, co‑creation, design critiques, usability synthesis sessions) to align teams on user problems and co‑create validated solutions.
Drive scalable research practices and templates (test scripts, recruiting screener templates, analysis frameworks) to accelerate research throughput and ensure consistent quality across projects.
Influence product prioritization by communicating cost/benefit analyses of usability issues and proposed design changes to product leadership and stakeholders.
Maintain a research repository and knowledge base of usability findings, design patterns, and validated solutions to promote reuse and institutionalize user insights.
Lead post‑release usability validations and retrospective analyses to measure the effectiveness of design changes and iterate on persistent pain points.
Serve as the escalation point for difficult usability trade‑offs, mediating between product, engineering, design, legal and business teams while advocating for the user.
Represent the usability discipline externally by presenting at industry events, sharing case studies, and contributing to hiring and interviewing to build a world‑class UX research organization.
Ensure research activities comply with legal, ethical and privacy standards (GDPR, CCPA) and internal policies, including secure handling of participant data and consent documentation.
Drive cross‑product standardization of interaction patterns and accessibility controls by partnering with design systems and front‑end engineering teams.

Secondary Functions

Support ad‑hoc usability requests and tactical research needs across product teams to unblock design and development with rapid, lean research sprints.
Contribute to the organization’s UX research strategy, tooling roadmap and research operations improvements to increase speed and quality of insights.
Collaborate with product owners and engineering to translate usability issues into technical requirements, acceptance criteria and backlog items.
Participate in sprint planning, agile ceremonies and design reviews to keep research insights tightly coupled with product delivery cadence.
Manage external research vendors and participant panels for specialized testing (e.g., assistive technology users, international markets) and negotiate contracts to ensure cost efficiency.
Run training sessions and internal brown‑bags to raise UX literacy, educate teams on usability best practices, and encourage data‑informed decisions.
Assist in recruiting, onboarding, and performance reviews for UX research hires, helping to shape job descriptions and interview processes.
Monitor competitor products and industry usability trends to inform strategic product differentiation and persistent usability improvements.
Provide synthesis of user insights into executive briefs, decision memos and ROI analyses to support strategic business cases.
Maintain documentation and dashboards of ongoing usability initiatives for transparency and cross‑team alignment.
