Webflow Developer / Front-End Engineer

Welcome to the video-first world

From your everyday PowerPoint presentations to Hollywood movies, AI will transform the way we create and consume content. Today, people want to watch and listen, not read — both at home and at work. If you’re reading this and nodding, check out our brand video.

Despite the clear preference for video, communication and knowledge sharing in the business environment are still dominated by text, largely because high-quality video production remains complex and challenging to scale—until now…

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
