About the role

The ideal candidate must have at least 2 years of industry experience, ideally more. They should have a passion for delivering accessible, optimised digital experiences. They must be comfortable working within a team and regularly presenting ideas and delivering technical briefings to both colleagues and clients.  We would also encourage applications from PHP developers who’s experience may not necessarily involve WordPress.

About us

Mixd is a highly respected user experience digital agency specialising in information design. Over the last 17 years, we have designed and built websites that are robust, usable, secure and meet user needs, using modern, open-source technologies for the NHS, Police, local Councils and many other public sectors. We are a multi-disciplined team of 13 designers, developers and UX experts and have established ourselves as one of the NHS’ leading digital partners working on a daily basis with NHS Clinical Commissioning Groups and NHS Trusts (including acute, mental health, community and ambulance trusts). We are also one of the leading providers of enterprise-ready WordPress solutions and bring open source solutions to the public sector. Ultimately, we’re a great place to work – you’ll love the environment, the people and the way the company looks after its staff.


Mixd has an agile approach to projects. Our team includes specialists in Discovery, UX, editorial, content migration and design that work closely with our clients to understand their goals and needs and use that to plan and roadmap our sprints so that our development team can focus on writing code.


Mixd have been advocates of accessibility for many years and as a minimum deliver websites that are fully compliant with the WCAG2.1 AA specification. We also believe in Accessible UX, working towards websites that provide an enjoyable experience regardless of the technology used to visit the site.

NHS Covid support

Over the last year, we are extremely proud to have supported the NHS in delivering critical solutions for the effective communication of information related to COVID-19. We developed a drop-in WordPress module for Coronavirus related news and updates for many of our NHS partners. We also developed and released a free coronavirus information microsite that could be deployed very quickly for public sector clients that we are extremely proud of.

Componentised frontend development

Mixd has developed a PHP based Server Side Rendered (SSR) component loading system that allows us to completely separate logic from presentation and also enables a development workflow comparable to javascript implementations such as React and Vue. We keep all our components organised using Fractal to create living design-systems for our projects.

  • Strong knowledge of WCAG 2.1 with practical accessibility testing experience.

  • Writing developer focussed documentation. 
  • Writing client focussed documentation.
  • Working to manageable deadlines.
  • Self-driven work ethic. You need to be a self-starter who loves taking initiative and seeing things through to completion.
  • You must have excellent communication skills (verbal and written) with the ability to listen and to articulate complex ideas clearly, vividly and concisely. You’ll demonstrate strong attention to detail and be confident in presenting at meetings and on sprint calls – both in person and via video calls.
