Core Responsibilities

Primary Functions

Create high-fidelity UI mockups and interactive prototypes using Figma, Sketch, Adobe XD or similar tools, ensuring visual polish, consistency, and alignment with product requirements and brand guidelines.
Translate wireframes, user flows, and UX specifications into pixel-accurate screens for web and mobile (responsive breakpoints), iterating quickly based on feedback from designers, product managers, and engineers.
Collaborate closely with product designers and UX researchers to incorporate user research findings and usability test outcomes into actionable UI improvements that increase task completion and reduce friction.
Implement and maintain reusable UI components in a design system (tokens, components, patterns), documenting usage rules and variations to accelerate team delivery and promote cross-product consistency.
Produce interactive prototypes and micro-interactions to communicate motion, transitions, and interaction states to stakeholders and engineering teams for validation and handoff.
Prepare developer-ready assets and redlines (SVGs, PNGs, icon sets, style tokens) and create clear handoff documentation (spacing, color values, typography scales) to facilitate accurate front-end implementation.
Support front-end engineers by providing CSS/HTML snippets, style guides, and component specifications, ensuring fidelity between design and shipped product across browsers and devices.
Participate in daily stand-ups, sprint planning, and design reviews to align design priorities with product roadmaps and engineering timelines, contributing estimates and scope suggestions.
Conduct visual QA of implemented UIs across devices and browsers to identify regressions, pixel misalignments, accessibility issues, and inconsistencies from design specifications.
Contribute to accessibility audits and remediation plans, applying WCAG best practices for color contrast, keyboard navigation, semantic HTML, and ARIA attributes to improve product inclusivity.
Iterate on onboarding flows, settings pages, dashboards, and core product screens to improve discoverability, conversion, and user satisfaction while tracking key UX metrics.
Design and optimize responsive layouts, grid systems, and breakpoints to ensure seamless experiences across mobile, tablet, and desktop viewports.
Create and maintain iconography, illustration guidelines, and visual assets that align with brand voice and improve the clarity of UI elements and affordances.
Collaborate with content designers and copywriters to ensure UI copy, microcopy, and form labels are clear, accessible, and aligned with design intent.
Run or support moderated and unmoderated usability tests (remote or in-person), synthesize findings, and produce prioritized recommendations for UI improvements.
Analyze product analytics and qualitative feedback (session recordings, heatmaps, NPS comments) to identify UI pain points and propose hypothesis-driven design experiments.
Design A/B test variations for UI experiments, document hypotheses and success metrics, and support results interpretation to iterate on winning solutions.
Maintain and update a living style guide, pattern library, and component inventory to reduce design debt and onboarding friction for new designers and engineers.
Assist in cross-functional design critique sessions, provide constructive feedback to peers, and incorporate feedback into rapid design iterations.
Work on end-to-end feature flows from discovery to delivery for small scoped features, taking responsibility for the visual implementation and collaborating through release cycles.
Support product launches by preparing marketing-ready assets, screenshots, and visual examples for app stores, release notes, and internal demos.
Proactively research emerging UI trends, accessibility techniques, and front-end tooling to recommend process improvements and innovations that enhance the user experience.

Secondary Functions

Support ad-hoc usability studies and exploratory design research to validate low-fidelity concepts and early prototypes.
Contribute to cross-team design system governance by documenting component usage, patterns, and versioning recommendations.
Assist engineers with visual regression testing and track UI bugs through issue trackers (JIRA, GitHub Issues), helping to reproduce and prioritize defects.
Help create onboarding materials and internal demos to educate stakeholders on new UI features and component updates.
Support the organization’s analytics and UX KPI tracking by tagging UI variations for experiment measurement and reporting.
Participate in UX workshops, design sprints, and ideation sessions to generate and refine feature concepts with product and engineering partners.
Prepare presentation decks and design rationale for stakeholder reviews, synthesizing design decisions and expected user outcomes.
Maintain an up-to-date portfolio of internship projects, including problem statements, process documentation, and final UI deliverables.
Assist in maintaining brand asset libraries (colors, logos, approved photography) and ensure adherence in product UI screens.
