About the role

  • We see growth as a creative practice, not a formula.
  • As AI makes execution faster and tactics easier to copy, creativity is the only lasting advantage.
  • In 2025, we raised a $100M Series C https://www.nytimes.com/2025/08/05/business/dealbook/clay-ai-marketing-fundraise.htmlbacked by world-class investors including Sequoia, CapitalG, and First Round - and crossed $100M in revenue.

Responsibilities

  • 5+ years of professional web development experience, with at least 3 years building conversion-focused websites and landing pages
  • Expert-level Webflow development skills, including advanced CMS implementations, custom code integration, and complex builds that push the platform's capabilities
  • Strong programming fundamentals in JavaScript/TypeScript, HTML5, and CSS3. You write clean, maintainable code that other developers can understand and build upon
  • API integration expertise-comfortable building REST API clients, implementing webhooks, handling OAuth flows, and debugging integration issues. You've connected web to CRMs, marketing automation platforms, and analytics tools
  • Build high-converting web experiences in Webflow.
  • You'll own the development of landing pages, conversion funnels, and website features from concept through launch.
  • This includes writing custom JavaScript for interactive elements, building CMS architectures, and pushing Webflow to its limits with advanced functionality.
  • Develop the technical infrastructure that powers growth.
  • You'll architect and implement the integrations, APIs, webhooks, and automation that connect our web to the broader marketing and sales stack.
  • This means building custom middleware, debugging complex integration issues, implementing event tracking architectures, and ensuring data flows seamlessly between Webflow, our CRM, analytics platforms, and marketing automation tools.

Nice to have

  • Experience with modern web development tools and frameworks: Git version control, Node.js, React (or similar), serverless functions, and build tools.
  • Familiarity with Three.js, GSAP, and animation libraries is a plus

Skills

  • Analytical thinking paired with business acumen. You understand how your code impacts conversion metrics, user behavior, and revenue
  • A get-it-done attitude with high standards. You ship, you iterate, you improve
  • Include code samples or GitHub repositories
  • Bonus points for:
  • Experience with analytics platforms (GA4, Segment, Mixpanel) and implementing custom tracking
  • Backend development experience or full-stack capabilities
  • Understanding of technical SEO and search optimization
  • Previous experience in high-growth startups or fast-paced environments
  • Contributions to open-source projects or technical writing
