Freelance Network | Mid-Senior Web Developer

We are looking for an experienced Freelance Mid-Senior Web Developer to join our freelance roster, supporting our current developers in our Experience Department on ambitious B2B website & product projects.

About the Role

This role is about building clear, performant, well-crafted web experiences from the ground up. You’ll be working across a varied mix of B2B projects, collaborating closely with UX, UI and project management to turn polished Figma designs into fast, accessible, best-in-class websites.

We are looking for people who care about their craft. You should have an eye for design detail, a grounding in best practices, and the experience to deliver well under fast-paced agency conditions.

The work

Work will be varied and you will support web development (primarily WordPress web development) across a mix of ambitious B2B projects, including:

• Full website builds and rebuilds across a wide range of sectors
• Work can range from landing pages, to lead-gen sites and through to full ecommerce and complex multilingual builds
• Projects involving older or established codebases requiring a careful hand
• Close collaboration with UX, UI designers, and project managers to turn supplied designs into performant, engaging websites

What you’ll bring to the role 

You’re an experienced web developer (front end and back end) with a strong WordPress background and a solid grasp of modern development practices. You’re comfortable working across the full range of what WordPress can be, from traditional templated builds to more modern Gutenberg / ACF Blocks based approaches, and you know your way around the wider ecosystem.

On the technical side, you’ll bring:

• Strong WordPress development experience, including familiarity with a wide range of implementations
• Solid hands-on experience with ACF and ACF blocks, as well as traditional WordPress templating approaches
• Fluency in SASS, JavaScript, PHP and HTML is a given and React and TypeScript experience is advantageous
• A thorough understanding of Version Control (BitBucket) including Git flow models
• Experience with WPEngine hosting environments and management would be beneficial and familiarity with Vercel is a bonus
• Solid grounding in web performance and accessibility best practices, (and a genuine desire to deliver them)
• SEO should be well understood along with delivering on-site technical SEO factors
• Experience with building custom WooCommerce sites and working with multilingual tools like Polylang would be beneficial.
• The ability to utilise AI tools to support and accelerate development, with the discipline to properly QA any AI-assisted output
• 
  

Beyond the core stack, you’ll also bring:

• A keen eye for design and the confidence to not only follow Figma designs precisely, but to flag potential issues and spot opportunities to add engagement, animation, and polish
• Experience designing or building on CMS platforms beyond WordPress, such as Payload, Webflow, Shopify, or modern headless setups
• Comfort working in an agency environment, with an understanding of time allocation, budgets, and delivery realities
• 
  

Experience we’re excited about

• A strong portfolio of website builds and digital work across a variety of sectors
• Demonstrated experience with ACF Blocks and modern WordPress development patterns
• A history of working closely with design teams and translating Figma into high quality, performant builds
