Full job description

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US.

As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations.

Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow.

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
