Core Responsibilities

Primary Functions

Lead end-to-end UI/UX design for web and mobile product features: conduct discovery, map user journeys, create wireframes, produce high-fidelity mockups, and deliver interactive prototypes that accelerate engineering implementation.
Plan and execute user research activities (interviews, contextual inquiries, surveys) to surface user needs, pain points, and behavioral patterns that inform product strategy and feature prioritization.
Conduct usability testing (remote and in-person) on prototypes and shipped experiences, synthesize qualitative and quantitative feedback, and iterate designs to measurably improve task completion and satisfaction metrics.
Design and maintain scalable design systems and UI component libraries (tokens, components, patterns) to ensure visual consistency, accelerate delivery, and improve cross-team collaboration.
Translate product and business objectives into clear interaction models, IA (information architecture), and low-fidelity flows that demonstrate user pathways and edge-case handling.
Produce pixel-perfect high-fidelity UI designs that meet brand guidelines and accessibility standards (WCAG 2.1), and hand off design specifications, assets, and annotations to engineering with clear acceptance criteria.
Create interactive prototypes (Figma, Framer, Principle, or similar) to validate interaction design, micro-interactions, and complex flows prior to engineering work.
Collaborate closely with product managers, engineers, content designers, and data analysts to align on scope, roadmap priorities, and measurable success criteria (KPIs, conversion metrics).
Use analytics tools (Google Analytics, Mixpanel, Amplitude) to analyze user behavior, conversion funnels, and feature usage to inform iterative product improvements and design hypotheses.
Own A/B and usability experiment design in partnership with product and data teams; translate experiment results into actionable design changes that improve retention, engagement, or conversion.
Advocate for accessibility and inclusive design practices across products; perform accessibility audits, provide remediation guidance, and QA designs for assistive technologies.
Create responsive and adaptive UI solutions that work across breakpoints and device types, including high-DPI and low-bandwidth scenarios.
Drive collaborative design workshops (design sprints, ideation, co-creation) to generate concepts, align stakeholders, and reduce ambiguity during early discovery phases.
Maintain a prioritized backlog of design tasks, clearly communicate trade-offs, and support sprint planning by estimating design effort and dependencies.
Mentor junior designers and interns, provide constructive design critique, and help raise team design maturity through reviews and documentation.
Produce clear design documentation and pattern guidelines that enable product teams to self-serve and maintain consistent UX across multiple product areas.
Create motion and interaction specifications (timing, easing, transition states) to convey intent to engineers and front-end developers for polished animations and micro-interactions.
Collaborate with marketing and brand teams to adapt product UI to campaigns, localization, and market-specific requirements while preserving core UX principles.
Participate in stakeholder meetings, articulate design rationale using data and research, and negotiate scope to ensure user-centered outcomes are prioritized.
Ensure end-to-end quality by participating in QA cycles, reviewing implemented UI, and iterating on visual polish and interaction details post-release.
Stay current with design trends, emerging UX patterns, platform conventions (iOS, Android, Web), and new tools to continuously improve design outcomes and team efficiency.
Translate complex product requirements into simple, elegant user interfaces that reduce cognitive load and improve user onboarding and first-time user experience.

Secondary Functions

Support cross-functional teams by producing quick prototypes for sales demos, executive reviews, and investor presentations.
Contribute to product roadmaps and design OKRs by providing feasibility assessments and impact estimates for proposed features.
Provide design input during sprint retrospectives and release planning to identify process improvements and design handoff optimizations.
Assist with localization and internationalization of UI elements and collaborate with translation teams to ensure UX integrity across languages.
Help maintain a centralized design asset repository with version control, naming conventions, and usage examples for internal teams.
Participate in recruitment and interviewing of design candidates; evaluate portfolios and provide feedback on fit and skill level.
