Core Responsibilities

Primary Functions

Lead the end-to-end planning, definition, and documentation of user interface architectures, including reusable component libraries, design tokens, and the governance model that ensures consistency across web and mobile experiences.
Translate product strategy and user research into actionable interface blueprints, wireframes, and high-fidelity prototypes that communicate interaction patterns, content hierarchy, and edge-case states to engineering and product teams.
Create and maintain a scalable design system: define components, variants, spacing and layout rules, accessibility attributes, and developer-ready tokens to accelerate implementation and ensure visual and interaction consistency.
Partner with Product Managers to map feature roadmaps to UI deliverables, prioritize interface work based on business impact, and define measurable success metrics such as task completion, conversion rate, and time-to-first-action.
Conduct and synthesize heuristic evaluations and usability testing sessions (moderated and unmoderated), analyze findings, and produce prioritized recommendations to improve discoverability, learnability, and efficiency of flows.
Define and document interaction specifications (micro-interactions, transitions, states) with clear acceptance criteria for front-end developers, including motion guidance and performance considerations.
Build and maintain detailed information architecture (IA) artifacts such as sitemap, content models, navigation schemas, and page templates that optimize findability and user flows.
Design cross-platform responsive strategies (mobile-first and adaptive) and specify breakpoints, layout behaviors, and component adaptations to ensure consistent experiences across devices.
Drive accessibility (WCAG 2.1/3.0 where applicable) compliance across UI components by specifying semantic HTML structures, ARIA attributes, keyboard/assistive technology support, and color contrast guidelines.
Lead cross-functional workshops (design sprints, journey mapping, story mapping) to align stakeholders on UX goals, prioritize user stories, and uncover technical or product constraints early in the design process.
Generate and maintain comprehensive UI documentation (pattern libraries, usage guidelines, do’s & don’ts) that makes design decisions discoverable and defensible across distributed teams.
Create task flows, personas, and scenario-driven interface specifications that connect business requirements and user needs to concrete interface solutions.
Mentor and provide constructive design critique for product designers and junior planners to elevate design quality and adherence to system standards.
Collaborate with front-end engineering leads to define handoff processes (Figma/Sketch to code), ensure component parity, and resolve implementation discrepancies using design tokens and CI/CD-friendly workflows.
Use analytics and qualitative research to run A/B tests and iterative experiments on UI variations, interpret results, and feed learnings back into the design system or feature backlog.
Manage and prioritize technical debt in UI components by maintaining a productized backlog for refactors, accessibility fixes, and performance optimizations.
Champion performance-minded UI decisions (asset sizes, render budgets, lazy-loading patterns) to optimize real-world loading times and interactive readiness across connections and devices.
Integrate content strategy and UX writing best practices into interface planning—defining microcopy, error messaging, and content hierarchy that reduce user friction and increase clarity.
Establish versioning, release notes, and change-communication practices for the design system so product teams can adapt to UI updates without breaking UX contract expectations.
Evaluate and select tools and processes for design collaboration including prototyping platforms, design system repositories, and developer handoff tools; pilot AI-assisted design tools for efficiencies (prompt-driven pattern generation, accessibility audits).
Liaise with legal, security, and compliance teams to ensure UI artifacts meet regulatory and privacy constraints (e.g., consent flows, data capture disclosures).

Secondary Functions

Support cross-team discovery sessions and provide UI feasibility input during early product discovery and technical scoping.
Maintain a backlog of UI improvements and coordinate with engineering to schedule iterative implementation within sprint cadences.
Produce onboarding guides and training sessions to help product teams adopt the design system and UI governance model.
Track industry trends and conduct competitive UI pattern audits to recommend modern, evidence-backed interface updates.
Assist in vendor evaluations for third-party UI libraries or front-end frameworks, advising on fit with system architecture and accessibility requirements.
Provide ad-hoc support for production issues related to UI regressions, style mismatches, or accessibility defects and help triage fixes.

Required Skills & Competencies

Hard Skills (Technical)
