Lateral Moves:

CMS Specialist (WordPress/Drupal)
Conversion Rate Optimization (CRO) Specialist or Digital Marketing Technologist

Core Responsibilities

Primary Functions

Design and implement responsive, mobile-first website layouts using semantic HTML5, modern CSS (Flexbox, Grid), and modular, maintainable SCSS/SASS or CSS-in-JS patterns to ensure consistency across devices and screen sizes.
Translate UX wireframes and high-fidelity designs from Figma, Sketch, or Adobe XD into production-ready front-end code while maintaining pixel accuracy and interactive behavior.
Build interactive UI components and reusable design system elements (buttons, forms, navigation, modals) and document component usage in a living style guide or Storybook.
Implement and optimize single-page applications (SPAs) and dynamic interfaces using modern JavaScript frameworks and libraries such as React, Vue.js, or Angular, ensuring accessibility and performance best practices.
Collaborate with product managers, UX researchers, content strategists, and back-end engineers to convert business requirements into technical specifications and prioritized feature plans.
Ensure web pages and applications meet accessibility standards (WCAG 2.1+, ARIA roles, keyboard navigation) and conduct audits and remediation for accessibility issues.
Optimize front-end performance: minimize render-blocking resources, implement code splitting, lazy-loading of images and components, and use modern image formats (WebP, AVIF) to improve Core Web Vitals.
Integrate websites with headless or traditional CMS platforms (WordPress, Contentful, Drupal, Sanity) to create flexible content templates that content editors can manage.
Implement SEO best practices in collaboration with SEO specialists: semantic markup, structured data (JSON-LD), meta tags, crawlability, and fast load times to improve organic search rankings.
Write clean, maintainable, and well-documented code with unit tests (Jest, Testing Library), and perform code reviews to uphold quality and consistency across the front-end codebase.
Set up and manage front-end build tooling and bundlers (Webpack, Vite, Rollup), task runners, and package managers (npm, Yarn) to streamline development and CI/CD workflows.
Create interactive prototypes and run usability testing sessions to validate design decisions, gather user feedback, and iterate rapidly.
Produce marketing-facing landing pages, email templates, and conversion-optimized UI elements in coordination with marketing and growth teams.
Integrate analytics, event tracking, and A/B testing tools (Google Analytics, GTM, Optimizely) to measure user behavior and inform data-driven design improvements.
Troubleshoot cross-browser compatibility issues and ensure consistent user experiences across Chrome, Firefox, Safari, Edge, and mobile browsers.
Manage version control workflows using Git, create feature branches, resolve merge conflicts, and maintain a disciplined commit history in collaboration with engineering teams.
Implement security best practices on the front end (input validation, output encoding, secure cookies) and work with back-end developers to protect user data and sessions.
Localize and internationalize UI elements and content, supporting multi-language sites and region-specific formatting and accessibility considerations.
Mentor junior designers and developers, provide constructive feedback during design critiques and code reviews, and help grow front-end and design capabilities within the team.
Plan, estimate, and scope project tasks for front-end work, balancing short-term deliverables with long-term maintainability and technical debt reduction.
Maintain brand consistency across digital touchpoints by enforcing style guides, typography, and color systems while adapting to platform-specific constraints.

Secondary Functions

Provide technical recommendations and feasibility assessments for new design and feature requests during discovery and roadmap planning.
Assist in pre-sales, client scoping, and RFP responses by preparing prototypes, technical estimates, and visual mockups.
Create onboarding documentation and training sessions for content editors on CMS templates, design systems, and publishing workflows.
Monitor production sites for performance regressions, broken links, and visual regressions; coordinate hotfixes and scheduled maintenance windows.
Participate in hiring, interviewing, and onboarding processes to grow the web design and front-end team.
