Core Responsibilities

Primary Functions

  • Own the end-to-end visual and interaction design of product features: create wireframes, high-fidelity mockups, interactive prototypes, and handoffs that clearly communicate intent to engineering and stakeholders.
  • Design and maintain a robust design system including reusable components, tokens, pattern guidelines, and documentation to ensure consistency across platforms and speed up delivery cycles.
  • Collaborate with product managers and UX researchers to translate user research, personas, and journey maps into interface solutions that address user needs and business goals.
  • Produce pixel‑perfect UI assets and specifications (grids, spacing, typography, color, iconography) and provide clear redlines and exportable assets for engineering implementation.
  • Build interactive prototypes in Figma, Framer, Principle, or similar tools to validate flows, micro‑interactions, and animation intent with stakeholders and test participants.
  • Work closely with front‑end engineers to implement UI components and ensure designs are feasible, accessible, and performant in production; participate in code reviews when requested.
  • Ensure all product interfaces meet accessibility standards (WCAG 2.1 AA or higher): conduct accessibility reviews, create remediation plans, and test with assistive technologies.
  • Create responsive and adaptive layouts that work across breakpoints and devices; define behavior rules for components across screen sizes and input methods.
  • Participate in iterative design sprints: rapidly explore multiple concepts, run internal critiques, and iterate based on usability test outcomes and analytics.
  • Produce and maintain UI documentation, component usage guidelines, and onboarding materials so design and engineering teams can adopt patterns consistently.
  • Run usability tests, remote moderated/unmoderated sessions, and A/B experiments; synthesize findings into design improvements that measurably improve task success and engagement.
  • Translate complex product flows into simple, intuitive interfaces that reduce cognitive load and support clear call-to-action hierarchy.
  • Optimize UI performance by advising on image optimization, lazy loading strategies, DOM complexity, and CSS architecture to improve perceived and actual page speed.
  • Provide thought leadership on visual design trends, accessibility best practices, and front-end capabilities; evangelize design process improvements across the organization.
  • Maintain brand integrity across digital touchpoints: enforce brand systems within product UI and collaborate with brand/marketing teams to align visual language.
  • Create motion and micro‑interaction specifications that guide engineering implementation and improve user feedback loops and task clarity.
  • Triage and QA UI implementations in staging and pre-release builds: verify pixel accuracy, responsive behavior, interaction fidelity, and accessibility remediation.
  • Drive cross‑functional design critiques and stakeholder reviews, collect actionable feedback, and close the loop on decisions with documented rationale.
  • Lead or mentor junior designers and interns: provide design reviews, guidance on workflows, and career development coaching to elevate team output.
  • Define and maintain versioning and release practices for UI components and design tokens so design system updates are predictable and backward compatible.
  • Collaborate with localization and content teams to ensure UI scales for internationalization, variable copy lengths, and right-to-left layouts when applicable.
  • Monitor product analytics, heatmaps, and user feedback to identify UI friction points, generate hypotheses, and prioritize design work that drives business metrics.
  • Coordinate with QA engineers to define UI acceptance criteria, test cases, and automation hooks for visual regression and component-level testing.
  • Manage stakeholder expectations and delivery timelines by scoping UI work, estimating design tasks, and communicating tradeoffs transparently.

Secondary Functions

  • Support cross-functional teams by creating quick design explorations and production-ready assets for marketing pages, landing experiences, and promotional micro-sites.
  • Contribute to the product roadmap by identifying UI technical debt and proposing prioritized refactors of legacy interfaces and components.
  • Conduct accessibility audits and partner with engineering to track and remediate WCAG violations and keyboard/ARIA issues.
  • Maintain a backlog of design improvements driven by analytics, customer support trends, and product learning sessions.
  • Assist in vendor evaluation and onboarding for design tools, prototyping platforms, and UX research services.
  • Support ad-hoc stakeholders with design consultations and rapid mockups to unblock sales, customer success, or support initiatives.

Required Skills & Competencies

Hard Skills (Technical)

  • Proficiency in Figma (components, variants, auto-layout), Sketch, or Adobe XD for interface design and prototyping.
  • Strong HTML5, CSS3 (including Flexbox and Grid), and responsive layout capabilities for close collaboration with engineering.
  • Working knowledge of modern JavaScript frameworks (React, Vue, or Angular) and component-driven development to ensure feasible handoffs.
  • Experience building and maintaining design systems, component libraries, and design tokens (e.g., Storybook, CSS-in-JS, tokens).

  • Proficiency with prototyping and motion tools (Framer, Principle, Lottie, After Effects) for micro-interactions and animated transitions.
  • Familiarity with version control concepts (Git) and design file versioning workflows for cross-team collaboration.
  • Experience writing detailed design specs, redlines, and developer-ready assets (SVG optimization, export workflows).
  • Usability testing and research skills: building test scripts, moderating sessions, synthesizing qualitative feedback, and translating learnings into design changes.
  • Analytics-driven design: ability to interpret product analytics (GA4, Mixpanel, Amplitude) and run A/B tests to validate UI hypotheses.
