Core Responsibilities

Primary Functions

Define and evolve the end-to-end UI architecture and front-end platform strategy, ensuring alignment with product roadmaps, business objectives, and enterprise technical standards.
Lead the design, build, and maintenance of a scalable, documented design system and component library (tokens, components, patterns) that enables consistent cross-product UI implementation and accelerates delivery.
Translate UX research, product requirements, and business goals into technical UI solutions and architectural proposals that include tradeoffs, constraints, and migration strategies.
Select, evaluate, and advocate for front-end frameworks and libraries (e.g., React, Angular, Vue) and core technologies (TypeScript, bundlers, state-management) that meet performance, maintainability, and developer experience targets.
Architect and implement micro-frontend and modular front-end patterns to enable independent deployment, easier scaling, and cross-team ownership while preserving design consistency.
Establish and enforce UI engineering standards, coding conventions, component APIs, accessibility guidelines (WCAG 2.1+), and style guides across the organization.
Drive accessibility-first initiatives: define accessibility requirements, lead audits and remediation plans, and ensure all new components meet WCAG and inclusive design best practices.
Create and maintain architecture documentation, decision records, interface contracts, and roadmap artifacts to provide transparency and continuity across teams.
Define testing and quality strategies for the UI stack, including unit testing, integration testing, visual regression testing, and end-to-end automation (Jest, Testing Library, Cypress).
Lead performance optimization efforts across rendering, asset loading, caching, and runtime performance; monitor front-end metrics and implement continuous improvements.
Collaborate closely with backend and API teams to design robust API contracts, data interactions, and error-handling patterns that support front-end resilience and scalability.
Design and implement CI/CD pipelines and release strategies for front-end deliverables, including linting, bundling, code-splitting, and automated deployments.
Drive security best practices for the UI, including XSS prevention, CSP, secure handling of tokens, and third-party dependency management.
Mentor, grow, and hire front-end engineers and UI specialists; provide technical leadership, run architecture reviews, and shape engineering culture and processes.
Facilitate cross-functional design and architecture reviews with product, design, QA, and platform teams to ensure feasibility, usability, and technical soundness before implementation.
Define metrics and KPIs for UI health (performance, accessibility, error rates, adoption of components) and report program-level progress and impact to stakeholders.
Lead migration and refactor strategies for legacy UI codebases to modern architectures, balancing risk, cost, and long-term maintainability.
Evaluate, adopt, and integrate front-end developer tools and observability solutions (RUM, synthetic monitoring, bundler analysis) to improve developer productivity and user experience visibility.
Drive internationalization and localization architecture for front-end applications, ensuring UI components properly support right-to-left (RTL) layouts and locale-specific formatting.
Coordinate and negotiate tradeoffs between product velocity and technical quality; prioritize technical debt remediation, platform maintenance, and new feature enablement.
Act as the steward of component lifecycle: deprecation policies, versioning strategies, backward compatibility guarantees, and migration guidance for product teams.
Serve as a primary point of contact for cross-team UI escalations, presenting architecture recommendations and leading remediation efforts for critical production issues.
Partner with design leadership to define token strategies (color, spacing, typography) and tooling that provide a single source of truth for design and engineering.
Advocate for front-end SEO best practices for SPAs and hybrid renderings including meta management, server-side rendering (SSR), and progressive hydration to improve discoverability and performance.

Secondary Functions

Support ad-hoc UI investigations and technical spike work to unblock teams and validate architectural approaches.
Contribute to the organization’s front-end roadmap, standards committee, and design system governance model.
Collaborate with data and analytics teams to instrument UIs for telemetry, track user behavior, and enable data-driven UX decisions.
Participate in sprint planning, agile ceremonies, and cross-functional rituals to ensure architectural alignment and delivery predictability.
Provide subject-matter expertise during vendor evaluations, procurement discussions, and proof-of-concept pilots for front-end solutions.
Produce internal training materials, workshops, and brown-bag sessions to raise front-end engineering and accessibility competency across the company.
Assist product teams with scoping estimates, technical feasibility reviews, and risk assessments for UI initiatives.
Monitor industry trends, emerging libraries, and open-source projects to recommend opportunities for innovation or cost savings.
