Experience Level: Mid-Level (2-5 years)

Remote Status: On-site

🚀 Role Summary

  • This role is integral to Synthesia's Marketing Website team, focusing on the global presentation and user experience of the company's digital presence.

  • The Webflow Developer/Front-End Engineer will be responsible for building, maintaining, and enhancing the marketing site, ensuring high performance, reliability, and user engagement.

  • The position requires a blend of Webflow expertise, front-end coding skills, and an understanding of supporting systems for SEO, experimentation, and growth initiatives.

  • This role offers significant ownership and impact, collaborating across Design, SEO, Growth, and Engineering to deliver cutting-edge web experiences.

📝 Enhancement Note: While the job title is "Webflow Developer / Front-End Engineer," the description strongly indicates a role within Marketing Operations or GTM Operations due to its focus on the marketing website, SEO, growth, and experimentation. The emphasis on "how Synthesia shows up to millions of users globally" and supporting "growth" initiatives aligns this position with operational functions that drive customer acquisition and brand perception.

📈 Primary Responsibilities

  • Develop and maintain website pages, components, and content within the Webflow platform, leveraging CMS capabilities and localization features.

  • Implement custom front-end functionality, including dynamic JavaScript interactions, engaging animations, interactive widgets, and robust form submissions.

  • Support and enhance internal SEO and automation tools, likely involving scripting and integration with cloud services.

  • Integrate with APIs and develop simple backend services to support website features and functionalities, potentially using serverless technologies.

  • Drive improvements in website performance, user accessibility (WCAG compliance), and technical SEO to optimize search engine visibility and user experience.

  • Collaborate closely with cross-functional teams including Design, SEO specialists, Growth Marketers, and core Engineering to translate strategic goals into tangible web solutions.

  • Actively participate in the entire development lifecycle, from implementation to iteration, maintaining high standards of code quality and deployment efficiency.

  • Contribute to the strategic direction of the marketing website's technical stack and development processes.

📝 Enhancement Note: The responsibilities clearly highlight a blend of front-end development and operational support for marketing initiatives. The mention of "supporting and extending internal SEO and automation tools" and "working with Lambda functions, APIs, and simple backend services" suggests a need for operational efficiency and system integration skills beyond standard Webflow development, fitting within a GTM or Marketing Operations framework.

🎓 Skills & Qualifications

Education:

  • Bachelor's degree in Computer Science, Web Development, Marketing Technology, or a related field, or equivalent practical experience.

Experience:

  • 2-5 years of professional experience in front-end development, with a significant focus on Webflow.

  • Proven track record of successfully building and launching complex websites or web applications in a production environment.

Required Skills:

  • Strong proficiency in Webflow, including CMS, dynamic content, and integrations.

  • Solid fundamentals in HTML5, CSS3 (including preprocessors like Sass/LESS if applicable), and JavaScript (ES6+).

  • Experience implementing custom JavaScript functionality, animations, and interactive elements.

  • Understanding of technical SEO concepts, including page speed optimization, structured data (Schema.org), mobile-first design, and indexing best practices.

Preferred Skills:

  • Experience with AWS services, specifically Lambda functions, basic infrastructure management, scripting, and cron jobs for automation.

  • Familiarity with Node.js or other server-side JavaScript runtimes for developing simple backend services.

  • Experience building or maintaining SEO tooling, web scrapers, content generators, or other automation scripts.

  • Familiarity with front-end build tools and modern JavaScript frameworks (e.g., React, Vue.js) for custom widget development.

  • Understanding of accessibility standards (WCAG) and best practices for inclusive web design.

📝 Enhancement Note: The required skills are heavily weighted towards front-end development and Webflow. However, the preferred skills, particularly AWS, Node.js, SEO tooling, and analytics, push this role towards a more operational and technical marketing function, common in GTM operations or marketing operations roles that manage the digital front-end. The experience level of "2-5 years" suggests a mid-level engineer who can work independently but also grow with the company.
