Senior Full Stack Engineer

We are looking for a Senior Full Stack Developer to design, build and maintain client websites, Shopify stores and custom web applications.

The work spans two areas. The first is WordPress and Shopify delivery: custom themes and plugins, store setup, app development and third-party integrations. The second is custom web application development: secure customer portals with role-based access, quotation and enquiry workflows, document management with controlled access, and user-facing dashboards.

This is a senior, hands-on role in a small team. You will own projects from discovery through to launch, make the technical calls on architecture and approach, work directly with clients, and help shape how we build. There is no layer between you and the decisions.

What you will be doing

• Developing and maintaining responsive WordPress websites, including custom themes and plugins
• Building and customising Shopify stores, including custom apps and third-party integrations
• Building secure customer portals covering registration, login, password reset, account profiles and role-based permissions
• Developing product catalogue interfaces, request-for-quotation workflows and enquiry history views
• Building document management functionality covering upload, categorisation, search, filtering, access permissions and activity records
• Designing and implementing user-facing dashboards and reporting views
• Integrating AI tools and APIs to extend web functionality, including document data extraction and content workflows
• Developing and integrating REST APIs
• Working with MySQL and PostgreSQL, including schema design
• Managing version control with Git and taking part in code review
• Maintaining CI/CD pipelines and using automation tools such as Gulp
• Testing across browsers and devices, fixing bugs and optimising performance
• Building to web accessibility standards and UK data protection requirements
• Supporting deployment, client handover and training
