Front End Developer

Frontend Developer (JavaScript / HTML / CSS)

Role overview

You’ll join a fast-paced agency environment, building high-quality, responsive frontends for a wide range of client projects—from landing pages and marketing sites to web applications and email campaigns.

If you enjoy shipping polished user experiences, collaborating closely with design, and taking pride in clean, maintainable front-end code, this role is for you.

What you’ll do

• Turn designs (Figma/PSD) into responsive, accessible, production-ready HTML/CSS.
• Build interactive UI features in modern JavaScript (and, where appropriate, frameworks such as React/Vue/Svelte).
• Support cross-browser compatibility and responsive behaviour across devices.
• Integrate frontends with APIs and work with data returned from back-end services.
• Build and maintain responsive HTML emails using best-practice techniques (including table-based layouts) and support testing across clients.
• Collaborate with designers, project managers and developers to deliver work to agreed timelines and quality standards.
• Contribute to continuous improvement—reusable components, performance, maintainability and clean code.

What you’ll bring

• Strong knowledge of semantic HTML5, modern CSS and responsive layout techniques.
• CSS frameworks (e.g., Bootstrap, Tailwind) and/or preprocessors (Sass/Less).
• Solid JavaScript fundamentals (ES6+), including DOM, events, async patterns and working with APIs.
• Experience building production websites or web app UIs and handling cross-browser issues pragmatically.
• Comfortable using Git-based version control.
• Familiarity with modern tooling (npm, bundlers/build tools) and writing maintainable, well-structured code.
• Design handover tools (Figma) and/or Adobe CC (Photoshop, Illustrator).

Helpful experience

• A JavaScript library or framework (e.g., React, Vue, Svelte, Alpine.js, jQuery).
• Email build and testing tools (e.g., Litmus, Email on Acid) and email platforms (e.g., Mailchimp, Campaign Monitor, dotdigital).
• Working in a ticketed workflow (e.g., Jira) and repository hosting (e.g., Bitbucket).
• CMS experience (e.g., WordPress, Umbraco).

Nice to have (a little back-end exposure)

• Basic PHP knowledge (enough to understand templates, make small changes and collaborate with back-end developers).
• Exposure to PHP frameworks (e.g., Laravel, Symfony) and/or WordPress theme development.
• Familiarity with databases (e.g., MySQL) and common web concepts (requests, sessions, authentication).
