Webflow Developer - Advanced SaaS Platform Build (Custom Code Integration Required)

About the Company

HireRivet is seeking a talented Webflow developer to build PermitProwler.com, a world-class AI-powered intelligence platform delivering real-time commercial permit alerts to subcontractors. This is a sophisticated SaaS product, not a marketing website—requiring expert-level technical implementation and custom code integration.

About the Role

This is an advanced Webflow Developer position focused on building a production-ready SaaS platform with custom code integration. You'll work remotely to implement a 5-page marketing website, a dynamic onboarding form system with webhook integration, and a full member dashboard connected to live database APIs. This role is perfect for experienced Webflow developers who excel at custom HTML/CSS/JavaScript implementation, API integration, and modern SaaS UI/UX design.

Responsibilities

• Design and implement a 5-page marketing website (home, pricing, features, how it works, contact) with responsive layouts and branded design systems
• Build and integrate a custom onboarding form system that submits JSON payloads to n8n webhooks and handles success/error responses
• Create a member dashboard with live Supabase database connectivity, user authentication via magic links, and dynamic data display
• Import and configure provided custom code blocks (~300 lines for forms, ~400 lines for dashboard) into Webflow with proper integration
• Configure Supabase JavaScript SDK and n8n webhook URLs to enable seamless API communication
• Ensure mobile-first responsive design across all pages and features for iOS and Android devices
• Test all integrations, form submissions, API calls, and dashboard functionality for production readiness
• Optimize page load times and implement smooth form validation with proper user feedback

Requirements

• 3+ years of proven Webflow development experience with a portfolio demonstrating advanced projects
• Expert-level proficiency in custom code embeds (HTML, CSS, JavaScript) within Webflow
• Proven experience connecting Webflow to external APIs and webhooks (REST API integration, JSON payloads)
• Experience with Supabase or similar database platforms and JavaScript SDK implementation
• Strong understanding of Webflow CMS, interactions, responsive design, and custom fonts/graphics
• Comfortable debugging network calls, API responses, and webhook integrations using browser developer tools
• Ability to build modern SaaS dashboards with clean, professional UI/UX standards (Stripe, Linear, Notion-level aesthetics)

Nice to Have

• Experience with n8n or similar workflow automation platforms
• Prior SaaS platform builds with live database connectivity
• Familiarity with Stripe payment links and integration
• Experience implementing magic link authentication flows
