Core Responsibilities

Primary Functions

Conduct and lead mixed-method user research (interviews, contextual inquiry, diary studies, and surveys) to uncover user needs, pain points, and behavior patterns that directly inform product strategy and design decisions.
Plan, design, and facilitate usability testing sessions (remote and in-person), synthesize findings, and translate test results into prioritized, actionable design improvements and roadmaps.
Create detailed user personas, empathy maps, journey maps, and scenario-based user flows to align cross-functional teams on the target user and user goals.
Define and iterate information architecture (IA), navigation schemas, and content hierarchies that improve discovery, findability, and overall information scent across the product.
Produce low-fidelity wireframes and high-fidelity interactive prototypes using Figma, Sketch, Adobe XD, or similar tools to validate interaction models, micro-interactions, and end-to-end user tasks before engineering implementation.
Design responsive interfaces and interaction patterns optimized for web, mobile (iOS/Android), and tablet, ensuring consistent behavior across breakpoints and device form factors.
Develop and maintain component-driven design systems and pattern libraries, documenting usage guidelines, tokens, accessibility rules, and handoff artifacts for engineers and designers.
Partner closely with product managers to translate business requirements and user research into prioritized feature specifications, acceptance criteria, and measurable UX success metrics.
Collaborate with engineering to ensure design intent is delivered accurately; provide annotated specs, redlines, assets, and participate in implementation reviews and QA.
Advocate and implement accessibility best practices (WCAG 2.1/2.2), conducting accessibility reviews and remediations to ensure inclusive design for users with diverse abilities.
Conduct heuristic evaluations and competitive analysis to benchmark experience quality and identify opportunities for differentiation and optimization.
Use analytics (e.g., Google Analytics, Mixpanel, Amplitude) and quantitative data to validate hypotheses, monitor feature adoption, track key UX metrics (task success, time-on-task, drop-off), and inform iterative design decisions.
Plan and run cross-functional design sprints and ideation workshops (co-creation sessions, story mapping, affinity mapping) to accelerate concept validation and align stakeholders.
Produce clear, persuasive presentations and design walkthroughs for stakeholders to communicate research insights, design rationale, trade-offs, and next steps.
Create and own UX deliverables for product features, including user stories, interaction specifications, clickable prototypes, visual comps, and developer-ready assets.
Iterate rapidly based on stakeholder feedback, user testing results, and instrumentation data, maintaining a bias toward validated learning and continuous improvement.
Define, track, and optimize product KPIs tied to user experience such as task completion rate, net promoter score (NPS), engagement, retention, and conversion funnel metrics.
Mentor and provide feedback to junior designers and interns; contribute to hiring and interview processes by reviewing portfolios, conducting design exercises, and assessing cultural fit.
Collaborate with content strategists and copywriters to craft UX copy, microcopy, and error states that guide users and reduce friction within flows.
Ensure brand consistency by implementing visual and interaction language aligned with brand design tokens, typography, color systems, and motion principles.
Support localization and internationalization efforts by designing flexible UI patterns that accommodate translation and regional content differences.
Contribute to product roadmaps by estimating UX effort, identifying technical dependencies, and advocating for user-centered prioritization in backlog grooming.
Influence cross-team processes by championing design thinking practices, establishing design ops patterns, and improving handoff workflows between design and engineering.

Secondary Functions

Support ad-hoc research requests from product and marketing teams, quickly scoping lightweight studies (surveys, guerilla testing) to answer immediate product questions.
Maintain and curate the team’s design repository, version control files, and accessible documentation to accelerate teammate onboarding and knowledge sharing.
Participate in sprint planning, stand-ups, and agile ceremonies to align on delivery timelines, scope, and dependencies.
Assist with QA testing and acceptance validation to ensure delivered experiences match design intent and meet accessibility and performance targets.
Provide training and internal workshops on usability heuristics, accessibility fundamentals, and prototyping tools to raise design maturity across the organization.
Help craft job descriptions, interview kits, and candidate evaluation templates for hiring designers and researchers.
Liaise with marketing and growth teams on UX-related experiments, A/B tests, and landing page optimizations to improve acquisition and conversion metrics.
Contribute to cross-functional retrospectives and post-launch reviews, documenting lessons learned and opportunities to improve design processes and outcomes.
