🚀 Role Summary

• This freelance role focuses on building and maintaining sophisticated job sites using Webflow, with a strong emphasis on robust data synchronization between Applicant Tracking Systems (ATS) and various external tools.

• Key responsibilities include developing real-time data flows, ensuring seamless vacancy, candidate, and status updates across platforms, and extending Webflow's capabilities with custom code and APIs.

• The position requires deep expertise in Webflow CMS, JavaScript, and automation tools like n8n, alongside a critical understanding of API integrations and data transformation in XML and JSON formats.

• Success in this role hinges on the ability to diagnose and resolve complex synchronization issues, manage webhooks effectively, and ensure the technical integrity and real-time accuracy of publicly facing job portals.

📝 Enhancement Note: This role is framed as a "Senior Webflow Developer" but the core responsibilities heavily lean into operational technology, data integration, and process automation, specifically for recruitment and HR tech stacks. The emphasis on ATS integration, data synchronization, and automation tools like n8n positions this as a critical GTM (Go-To-Market) or Revenue Operations adjacent role, focused on the efficiency of candidate acquisition and talent management systems.

📈 Primary Responsibilities

• Develop, customize, and maintain dynamic job sites and career portals on the Webflow CMS, ensuring responsive design and optimal user experience for job seekers.

• Design, implement, and troubleshoot complex data synchronization workflows between Webflow, Applicant Tracking Systems (ATS), and other third-party services using n8n and REST APIs.

• Build and manage integrations for publishing vacancies, capturing candidate applications, and updating applicant statuses in real-time across integrated platforms.

• Consume, transform, and map data between different systems, primarily handling XML and JSON data formats for seamless information flow.

• Extend native Webflow functionality by leveraging the Webflow API, custom JavaScript, HTML, and CSS to create advanced features and unique user interfaces.

• Implement advanced CMS functionalities such as dynamic filtering, pagination, and site-wide search, often utilizing tools like Finsweet Attributes for enhanced capabilities.

• Set up, configure, and maintain tracking codes and events using Google Tag Manager (GTM) for analytics and performance monitoring of job sites.

• Maintain version control for all code and configurations using Git/GitHub, ensuring a robust and traceable development process.

• Document all integrations, automation workflows, and technical processes thoroughly to facilitate knowledge transfer and ongoing maintenance for the JumpSeat team.

• Proactively diagnose, troubleshoot, and resolve synchronization failures, webhook errors, and API call exceptions to ensure continuous operational uptime.

📝 Enhancement Note: The responsibilities highlight a blend of front-end development (Webflow, JS, HTML, CSS) and back-end integration/automation (APIs, n8n, data sync). For operations professionals, the emphasis on "data synchronization," "ATS integrations," and "automation flows" is critical, indicating a role that directly impacts the efficiency and reliability of a core business process (recruitment).
