Core Responsibilities

Primary Functions

Translate product requirements, user research, and design direction into high‑fidelity, coded prototypes that demonstrate micro‑interactions, animation timing, accessibility states, and complex UI behavior for stakeholder validation and usability testing.
Build and maintain production‑ready UI components and patterns using HTML5, modern CSS (including CSS Modules, CSS‑in‑JS or utility frameworks), and JavaScript frameworks (React, Vue, or similar), ensuring components are documented and versioned for reuse.
Lead the development, evolution and governance of the organization’s design system — authoring component APIs, theming tokens, usage guidelines, accessibility rules (WCAG), and contribution workflows so designers and engineers can scale experiences consistently.
Collaborate with cross‑functional teams (product managers, engineers, user researchers, QA) to scope technical feasibility, estimate work, and define acceptance criteria for interactive features and UI implementations.
Rapidly prototype alternative interaction concepts (including AR/VR, voice, and motion prototypes where applicable) to validate hypotheses, reduce ambiguity for engineering, and inform product roadmaps.
Implement and optimize front‑end performance for complex interfaces: lazy loading, code splitting, efficient render strategies, ARIA optimization, and minimizing runtime costs to improve perceived and measured performance.
Author well‑tested, accessible code and automated tests (unit, visual regression, integration) for UI components to ensure long‑term reliability and to reduce regressions during scaling and refactors.
Work hands‑on within the codebase to ship features alongside engineering teams — owning interface code for assigned features from design hand‑off through QA and production deployment.
Define and maintain visual tokens (color, typography, spacing) and ensure these tokens are wired to themeable, platform‑agnostic systems (web, native, email) to enable consistent branding across channels.
Conduct UI audits and gap analyses of existing products, recommending refactors, accessibility remediations, and standardization opportunities to reduce technical debt and design inconsistencies.
Mentor and pair with product designers and front‑end engineers to upskill teams in prototyping tools, componentization best practices, and performance‑aware design decisions.
Create clear documentation, usage examples, code snippets, and living style guides that enable non‑technical designers to understand implementation constraints and engineering teammates to adopt design patterns quickly.
Run and analyze design experiments and A/B tests for interactions or microcopy; translate results into actionable improvements that balance conversion, usability, and maintainability.
Integrate design tools (Figma, Sketch, Adobe XD) with developer toolchains and component libraries — enabling tokens export, auto‑generated code snippets, and CI/CD pipelines for UI asset publishing.
Advocate for accessibility and inclusive design — perform automated and manual accessibility testing, remediate issues, and educate teams on accessible interaction patterns, keyboard flows, and assistive technology compatibility.
Set up and maintain front‑end build systems, component storybooks (Storybook, Bit), and developer experience improvements to shorten the feedback loop between design and engineering.
Collaborate on mobile and responsive behavior for multiple breakpoints and platforms, ensuring component adaptability and consistent interaction patterns across device sizes and input methods.
Work with backend and platform teams to define contracts (APIs, JSON schemas) for UI-driven features, ensuring data structures support efficient rendering and progressive enhancement strategies.
Participate in product discovery and sprint planning; surface technical risks, propose low‑cost prototypes, and identify opportunities to reduce time‑to‑market while preserving UX integrity.
Champion metrics‑driven design by working with analytics/opt teams to instrument interactions, define success KPIs, and iterate on UI improvements based on quantitative data.
Contribute to hiring, interviewing, and onboarding practices for design engineering roles; help establish hiring criteria and technical assessments for future teammates.
Stay current on web standards, emerging interaction models (motion design, micro‑interactions, conversational UI), and front‑end tooling; recommend and pilot new tools that reduce friction in the design → code workflow.
Coordinate cross‑team launches by preparing implementation checklists, regression testing plans, and post‑launch monitoring for UI stability and performance.
Advocate for a culture of reuse and component stewardship: track technical debt, propose deprecation plans for outdated patterns, and prioritize component maintenance in roadmaps.

Secondary Functions

Support product managers, UX researchers, and designers by delivering interactive artifacts for user testing and stakeholder demos on an as‑needed basis.
Contribute to strategic roadmaps by estimating cost and complexity of UI initiatives and identifying opportunities for reuse and automation.
Assist in triaging production UI issues that affect user experience, providing hotfixes or mitigation strategies in partnership with on‑call engineering teams.
Participate in sprint ceremonies (planning, standups, demos, retrospectives) and help the team maintain a high‑velocity, quality‑focused workflow.
Provide occasional training sessions and workshops on prototyping tools, component-driven design, and front‑end best practices to cross‑functional teams.
Help curate internal knowledge bases and repositories (wiki pages, design system docs) to ensure institutional knowledge is preserved and discoverable.
