🎯 Role Definition

The Web Animator creates and implements motion and interactive animation for web and mobile interfaces, marketing campaigns, and digital product experiences. This role merges creative motion design with front-end skills (HTML5, CSS3, JavaScript) to produce lightweight, accessible, cross-browser animations—ranging from microinteractions and SVG/CSS transitions to complex timeline animations powered by GSAP, Canvas, or WebGL. The Web Animator partners closely with UX/UI designers, front-end developers, product managers, and marketing teams to storyboard concepts, prototype interactions, export production-ready assets (Lottie/Bodymovin, sprite sheets), and ensure performance and analytics-driven iteration.

Core Responsibilities

Primary Functions

  • Conceptualize, storyboard, and pitch animated concepts and interaction flows for web pages, landing pages, mobile apps, and digital ad campaigns, aligning motion with product goals and brand guidelines.
  • Design and author high-fidelity animation prototypes using After Effects, Lottie, Adobe Animate, or equivalent tools and translate those prototypes into production-ready HTML5/CSS3/JavaScript implementations.
  • Implement performant SVG, CSS, and JavaScript-based animations for microinteractions, transitions, and hero animations, ensuring smooth 60fps motion where possible across modern browsers and devices.
  • Build complex timeline-based animations using GSAP (GreenSock) or similar libraries, optimizing tweens, timelines, and lazy-loading strategies to minimize jank and CPU/GPU load.
  • Export and integrate Lottie (Bodymovin) JSON animations into web and mobile projects, troubleshooting compatibility issues, and converting After Effects assets for runtime use.
  • Create Canvas- and WebGL-based interactive experiences (Three.js or raw WebGL) for immersive visuals, parallax, and data-driven motion when vector/SVG approaches are insufficient.
  • Produce lightweight HTML5 banner ads and animated creatives following IAB specifications, tag formats, and ad platform delivery constraints while maintaining visual fidelity.
  • Collaborate with front-end engineers to integrate animations into component-driven frameworks (React, Vue, Angular), encapsulating motion as reusable components and respecting framework lifecycles.
  • Convert static UI designs into motion-enhanced interfaces, defining easing, duration, and choreography rules to improve usability and perceived performance across touch and pointer interactions.
  • Optimize animation assets and delivery (minifying JSON, compressing sprites, using vector over bitmap where appropriate) to meet strict weight budgets and improve page load and Core Web Vitals.
  • Ensure all animations meet accessibility requirements, provide alternatives or reduced-motion modes, and adhere to WCAG guidance and system-level prefers-reduced-motion settings.
  • Conduct cross-browser and cross-device testing, debug render and timing inconsistencies, and implement fallbacks for older browsers or low-power devices.
  • Maintain an organized animation asset library, documenting naming conventions, export presets, reusable motion tokens, and component APIs for other developers and designers to consume.
  • Collaborate with product and UX teams to define motion specifications in design systems, documenting intent (affordance, feedback, continuity) and technical constraints for consistent behavior.
  • Iterate on animations using analytics and A/B testing results to measure engagement uplift, CTR, and conversion impact, and adapt motion strategies based on data.
  • Manage handoff processes, producing clear spec sheets, frame-accurate screenshots, or code snippets for engineering implementation, and participate in release triage to resolve animation regressions.
  • Mentor and review work from junior animators or contractors, providing feedback on timing, easing, export fidelity, and production code practices.
  • Support campaign planning by estimating animation effort, scoping deliverables for sprints, and pacing work to meet marketing and product deadlines.
  • Integrate asset version control workflows (Git) for animation code and scripts, and coordinate with design/versioning tools to track iterations and rollback when necessary.
  • Troubleshoot runtime issues in staging and production, profiling memory and paint/reflow bottlenecks, and implementing fixes to improve battery life and performance on mobile devices.
  • Build and maintain demo pages, styleguides, and motion pattern libraries that illustrate best practices, accessibility settings, and recommended animation primitives for product teams.
  • Coordinate with QA and localization teams to validate animation across languages, ensure text-only or RTL compatibility, and confirm that motion doesn’t interfere with translated layouts.

Secondary Functions

  • Provide ad-hoc creative support for marketing needs such as social motion clips, animated email header GIFs, and promo microsites.
  • Contribute to the organization’s design system and motion guidelines, proposing new motion tokens and documenting their intended use cases.
  • Assist in vendor and freelance coordination—onboarding external animators, reviewing deliverables, and ensuring consistent technical handoffs.
  • Train designers and engineers on animation best practices, export techniques, and efficient use of libraries like GSAP and Lottie.
  • Research and propose new tools, libraries, or workflows (e.g., vector optimization, runtime rendering approaches) that reduce build weight or improve production velocity.
  • Maintain and update internal tooling scripts for automating exports (Bodymovin scripts, batch SVG optimizers) and validating asset compatibility.
  • Participate in sprint planning, grooming, and agile ceremonies to align animation work with product milestones and delivery expectations.
  • Track animation performance KPIs post-release and produce short reports with recommended technical or creative optimizations.
  • Support accessibility audits and remediation, updating animations or implementing reduce-motion fallbacks as required by policy or law.
  • Provide technical estimates and risk assessments for large-scale animation initiatives, advising product leadership on feasibility and timeline.
