Core Responsibilities

Primary Functions

Plan, recruit, and moderate usability tests (remote and in-person), synthesize qualitative observations and quantitative metrics, and produce clear, prioritized recommendations to improve task completion rates, conversion funnels, and overall product usability.
Assist in designing and conducting user interviews, surveys, diary studies, and contextual inquiries; transcribe and code qualitative data then produce research artifacts like affinity maps, journey maps, and insight reports for stakeholders.
Create low- and mid-fidelity wireframes, interactive prototypes, and annotated design specifications using Figma, Sketch, Adobe XD, or Axure to communicate interaction patterns, screen flows, and micro-interactions to product and engineering teams.
Maintain and update the organization’s design system and component library, document usage guidelines, accessibility attributes, variant combinations, and code-ready assets to ensure visual and interaction consistency across platforms.
Collaborate with product managers and engineers in agile workflows to translate user needs into clear acceptance criteria, user stories, and UX tasks during sprint planning and backlog refinement.
Conduct heuristic evaluations and expert reviews of web and mobile interfaces against established UX best practices, accessibility standards (WCAG 2.1+), and internal design principles, then propose prioritized remediation plans.
Analyze product analytics (Google Analytics, Mixpanel, Amplitude) and A/B test results to identify usability issues, drop-off points, and opportunities for UX optimization; convert data trends into design experiments.
Prepare polished UX deliverables — research reports, personas, customer journey maps, usability test videos, and executive presentations — that communicate insights and recommended design changes clearly to non-design audiences.
Support UX writing and microcopy reviews across flows (onboarding, error states, empty states) to ensure consistent voice, clarity, and accessibility that reduce user friction and improve task success.
Assist in accessibility testing and remediation, including keyboard navigation checks, screen reader validation, color contrast audits, and documenting accessibility bugs for remediation by engineering.
Create and maintain user personas and scenario-based task flows that inform product decisions and help prioritize features according to user needs and business impact.
Facilitate cross-functional workshops, design sprints, and co-creation sessions with stakeholders and end users to align on problem definitions, ideation, and prototype validation steps.
Prepare and maintain UX test plans, recruitment screener criteria, incentive guidelines, and detailed test scripts to ensure consistent, unbiased usability research and defensible insights.
Conduct competitive and market UX analyses identifying industry patterns, best-in-class interaction models, and opportunities for differentiation that feed into product strategy and roadmap prioritization.
Assist in onboarding and mentoring interns or junior contributors by sharing research practices, design tooling tips, and product knowledge to scale UX efforts across the organization.
Monitor and triage user feedback channels (in-app feedback, support tickets, app store reviews) to identify recurring usability issues, feature requests, and quick wins for product improvements.
Create clickable prototypes and exploratory concepts for early-stage features and collaborate with engineers to scope technical feasibility and implementation trade-offs.
Document UX decisions, design trade-offs, and post-launch learnings to build organizational knowledge, support hypothesis-driven iterations, and enable faster future design cycles.
Support quality assurance by validating UI implementations against design specs, checking pixel accuracy, interaction states, and accessibility behavior prior to release.
Coordinate participant recruitment with external vendors or internal panels, manage scheduling and consent forms, and ensure research studies meet ethical and privacy standards.
Build and maintain a UX research repository and searchable library of past studies, transcripts, recordings, personas, and artifacts to enable rapid reference and avoid duplicate research.
Translate quantitative survey and analytics results into human-centered insights, running basic statistical summaries and visualizations that inform design trade-offs and stakeholder prioritization.
Help define and track UX success metrics (task completion, time-on-task, SUS, NPS) and establish regular reporting cadences to measure the impact of design changes over time.
Support rapid iteration cycles by preparing test-ready prototypes and coordinating quick guerrilla usability tests with internal teams or pilot users.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis in collaboration with product analytics to answer UX hypotheses and measure experiment outcomes.
Contribute to the organization's UX strategy and roadmap by surfacing user pain points, synthesizing customer feedback, and recommending prioritized design initiatives.
Collaborate with business units and engineering to translate research findings into technical requirements and acceptance criteria that are implementable within sprint cycles.
Participate in sprint planning, backlog grooming, and agile ceremonies to ensure UX work is sequenced with development and QA efforts.
Assist marketing and customer success with UX assets for release notes, feature education, and onboarding materials to improve adoption and reduce churn.
Support localization and internationalization efforts by validating UX flows for cultural and language considerations and coordinating with translation teams.
Maintain professional awareness of UX, accessibility, and product design trends by attending meetups, conferences, and internal knowledge-sharing sessions.
