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

- 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
