About the Role

This role sits within ourMarketing Website team, responsible for how Synthesia shows up to millions of users globally.

As aWebflow 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 inWebflow (CMS, localization, integrations)

  • Implementingcustom front-end functionality (JavaScript, animations, interactive widgets, forms, experiments)

  • Supporting and extending internalSEO and automation tools (currently running on AWS)

  • Working withLambda 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 withWebflow in a production environment

  • Solid fundamentals inHTML, CSS, and JavaScript

  • Comfortable working outside Webflow when needed (custom JS, embeds, APIs)

  • Experience withtechnical SEO concepts (page speed, structured data, indexing basics)

Some extra skills that would be awesome

  • Experience withAWS (Lambda, basic infrastructure, scripts, cron jobs)

  • Familiarity withNode.js or similar backend runtimes

  • Experience building or maintainingSEO 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 spansWebflow, 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

Where to Advertise Data Science Jobs in the UK (2026 Guide)

Advertising data science jobs in the UK requires a different approach to most technical hiring. Data science spans a broad and often misunderstood spectrum — from statistical modelling and experimental design through to machine learning engineering, product analytics and AI research. The strongest candidates identify firmly with specific subdisciplines and are frustrated by adverts that conflate data scientist with data analyst, business intelligence developer or machine learning engineer. General job boards produce high application volumes for data roles but consistently fail to match specialist data science profiles with the right opportunities. This guide, published by DataScienceJobs.co.uk, covers where to advertise data science roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

How Many Data Science Tools Do You Need to Know to Get a Data Science Job?

If you’re trying to break into data science — or progress your career — it can feel like you are drowning in names: Python, R, TensorFlow, PyTorch, SQL, Spark, AWS, Scikit-learn, Jupyter, Tableau, Power BI…the list just keeps going. With every job advert listing a different combination of tools, many applicants fall into a trap: they try to learn everything. The result? Long tool lists that sound impressive — but little depth to back them up. Here’s the straight-talk version most hiring managers won’t explicitly tell you: 👉 You don’t need to know every data science tool to get hired. 👉 You need to know the right ones — deeply — and know how to use them to solve real problems. Tools matter, but only in service of outcomes. So how many data science tools do you actually need to know to get a job? For most job seekers, the answer is not “27” — it’s more like 8–12, thoughtfully chosen and well understood. This guide explains what employers really value, which tools are core, which are role-specific, and how to focus your toolbox so your CV and interviews shine.
