About the Role
This role sits within our Marketing Website team, responsible for how Synthesia shows up to millions of users globally. As a Webflow Developer / Front-End Engineer, you’ll work across Webflow, front-end code, and supporting tooling. You’ll collaborate closely with Design, SEO, Growth, and Engineering, and you’ll have real ownership over what ships to production. Your mission is simple: build fast, reliable, and high-performing experiences on our marketing site, and help maintain the systems that support SEO, experimentation, and growth.
What you’ll be working on:
- Building and maintaining pages and components in Webflow (CMS, localization, integrations)
- Implementing custom front-end functionality (JavaScript, animations, interactive widgets, forms, experiments)
- Supporting and extending internal SEO and automation tools (currently running on AWS)
- Working with Lambda functions, APIs, and simple backend services where needed
- Improving performance, accessibility, and technical SEO
- Collaborating closely with Design, SEO, Growth, and Engineering
- Shipping fast, iterating often, and keeping quality high
Skills and requirements
Must-have skills/experience:
- Strong experience working with Webflow in a production environment
- Solid fundamentals in HTML, CSS, and JavaScript
- Comfortable working outside Webflow when needed (custom JS, embeds, APIs)
- Experience with technical SEO concepts (page speed, structured data, indexing basics)
Some extra skills that would be awesome:
- Experience with AWS (Lambda, basic infrastructure, scripts, cron jobs)
- Familiarity with Node.js or similar backend runtimes
- Experience building or maintaining SEO tooling, scrapers, generators, or automation
- Knowledge of analytics and tracking setups (GA4, GTM, events)
- Experience working in a product-led or growth-focused environment
How we work:
- Small team, high ownership, and meaningful impact
- Webflow is our main platform — but we regularly extend it with custom code and build custom tooling
- We care deeply about performance, maintainability, and clean implementations
- You’ll have real influence over technical decisions, tooling, and how things are built
This role is not for you if:
- You only want to design in Webflow Designer and avoid code
- You’re uncomfortable touching JavaScript or backend logic
- You prefer rigid specs over solving open-ended problems
Why this role is unique:
- Production traffic at real scale
- A role that spans Webflow, front-end engineering, and backend tooling
- Ownership over both UI and the systems behind it
- Room to grow inside one of the fastest-growing AI companies
