Job description

Overview

We’re looking for a senior front-end web developer who cares deeply about the interactive details — design, animation, and behavior — that bring a brand to life. You’ll join our design-driven team building custom websites from scratch for interesting clients.

You will lead end-to-end website development, choosing the appropriate tech stack (often Craft CMS), establishing technical architecture, crafting intuitive content authoring experiences, and writing resilient front-end code to allow clients to easily create new pages, and manage and evolve their sites post-launch.

Working closely with designers, content strategists, and project managers, you'll turn designs into fast, accessible, responsive, and animated websites. You’ll contribute throughout the project lifecycle — from initial strategy, to wireframe and design reviews, technical architecture, front-end development, interactions and animations, to testing and final quality assurance.

You’ll also collaborate with your peers on the development team to improve our processes and perform regular maintenance and enhancements to hosted client sites.

Primary Responsibilities

• Define technical requirements through research and collaboration with designers and project stakeholders
• Lead development on small to large-scale websites as the primary individual contributor
• Architect and implement the CMS content editing experience for clients
• Translate bespoke design mockups in Figma into modular, reusable front-end component systems
• Propose and implement performant animations and interactions that enhance the user experience
• Ensure cross-browser compatibility and responsive behavior across devices and platforms
• Lead client-facing demos and technical discussions, bridging the gap between technical and non-technical teams
• Perform quarterly maintenance to keep projects secure, stable, and up to date
• Enhance and extend client sites to meet new business and audience needs
• Contribute to internal tools, workflows, and development standards
• Support teammates with development challenges

About You

• 3+ years of experience in an agency or similar environment
• Strong portfolio demonstrating attention to craft, detail, and design-led work
• Deep appreciation for design, branding, and the role of front-end in shaping user experience
• Passion for refined interfaces, thoughtful animation, and interactive experiences
• Experience building modular systems with a CMS and reusable components
• Mobile-first mindset with solid knowledge of common cross-browser issues
• Strong understanding of web performance, accessibility, and SEO best practices
• Familiar with WCAG AA accessibility standards
• Experience or Interest in using AI to enhance the velocity of development or open up new possibilities
• Comfortable working across multiple projects and navigating tight timelines
• Excellent communicator who collaborates well with designers and other developers
• Curious, self-motivated, and committed to continuous learning and improvement

Nice to Have

• Experience working with Craft CMS, Shopify, Wordpress, or Astro
• Background in design or motion
• Experience with animation libraries like GSAP or Framer Motion
• Experience implementing Lottie or Rive animations
• Familiarity with TailwindCSS and BEM methodology
• Experience with PHP (Craft, WordPress, or Laravel)
• Experience with front-end frameworks like React/Next or Vue
• Experience with 3D or creative development (three.js, shaders, animations using canvas or WebGL)
• Interest in CI/CD or DevOps workflows

Relationships

• Manager: Executive Director, Operations
• Mentors: Principal Developers
• Peers: Developers, Senior Developers
• Collaborates with: Associate Creative Directors, Creative Directors, Project Managers, Account Directors, SEO/Analytics Experts
