About the role

As a Senior WordPress Engineer you will bring a blend of front-end and back-end expertise, leading the planning and development of projects, features, functionality and logic across enterprise-level projects for the NHS and other public sectors. WordPress experience is essential and the ideal candidate has previous experience in a senior position. Prior experience working in the public sector is also favourable.

A comprehensive understanding of the components and technologies related to WordPress is essential to this role. To enable you to develop complex WordPress projects, you should also have expert knowledge of the larger WordPress ecosystem, including commonly used third-party libraries. You must have excellent knowledge of modern web technologies and best practices, including semantic HTML,modern CSS, and extensive experience building PHP applications. You should also have a solid understanding of MySQL and database-driven applications. You will be familiar with the tools required for engineering projects including a good understanding of Git, local development environments, PHP configuration, coding standards, accessibility and information security. You should also be willing to adapt and help evolve our established processes at Mixd.

The responsibilities and expectations of a Senior Engineer are not necessarily tied to a specific project. While you will need to apply your skills on each project you are assigned to, you are also expected to set a similar example when interacting with the whole engineering team for meta-level tasks. This could be cross-project code reviews, helping other engineers debug problems, coaching, or offering advice and architectural guidance to other projects. You will lead by example when working on projects, meeting with clients and giving feedback to peers. It’s both your responsibility to voice concerns about technical decisions being made, but also have the distance and maturity to accept decisions made by the team and/or project technical lead and commit yourself to build solutions in the agreed-upon way.


About you:

We are looking for a senior engineer with a passion for pushing forward with new technologies in the WordPress space and a track record of building commercially successful digital projects. You should consider yourself an expert when it comes to WordPress best practices and have a history of developing for the Gutenberg editor. You should be experienced leading a project development team, advising on best practices to promote efficient development sprints. You should have practical experience developing accessible and inclusive websites to WCAG 2.2 AA standards. UK public sector experience is extremely desirable.



We work remotely from home, or you can choose to work from our studio in Leeds for some or all of the time. This means you will need to work both independently and as part of a remote team. We’re on the lookout for top talent nationwide, so don’t let location hold you back from applying. We welcome candidates from all over the UK however, please note that you will be required to attend in person for some events, so expect some travel to our Leeds office.

We organise regular socials throughout the year and you will have the opportunity to meet the rest of the company at our annual meetup. We care about good communication and you should be able to prioritise your work and meet deadlines, discussing any problems with the team along the way. One size doesn’t always fit all when it comes to working arrangements. So we’re happy to talk about what might be possible to help you balance work with your other commitments. We also offer support if you’re returning after time out of the job market.

Benefits package:

We offer a competitive salary, negotiable depending on qualifications and experience. On top of this we have a generous benefits package, including pension scheme, flexible hours, 25 days holiday growing to 30 days over time (and your birthday off), social events and our annual retreat, electric vehicle and cycle to work schemes and a wellbeing health and fitness allowance.

Career development:

From our clients to our teams, everything we do centres around people. That is why we feel it is critical to apply this approach to our business and our people. We encourage our people to grow, expand and pursue changing interests in a supportive and encouraging environment. We have career progression frameworks and offer clearly defined routes from junior to senior levels across departments. Our line managers are here to give you guidance and advice tailored to your interests and goals. Additionally, as a small company, employees have the unique opportunity to actively contribute to our success and play a crucial role in shaping our processes and strategies. You will also get a budget of £1,000 per year for your own personal learning and development.

About us:

Established in 2004, we have earned a reputation for specialising in designing fast, accessible websites for the NHS. We champion web accessibility and user-centred design principles, designing simple and intuitive digital services that meet user needs. We are a multidisciplinary team of designers, engineers and delivery experts with a diverse mix of user experience design expertise.

We are also one of the leading providers of enterprise-ready WordPress solutions in the UK and bring open source solutions to the public sector. We are involved in the wider accessibility community, running training and contributing to WCAG standards. We have developed our own Gutenberg Block Library (based on the NHS Digital Service Manual) and a PHP based Server Side Rendered (SSR) component 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.

Over the past 20 years, we have helped public sector teams create and run great public services – things like helping the NHS implement a COVID-19 communications platform (which we did completely free of charge) and looking at how to improve digital services for dozens of NHS Trusts including Leeds Teaching Hospitals NHS Trust and Alder Hey Children’s Hospital.

Diversity and inclusion:

We are wholeheartedly dedicated to promoting diversity, equality and inclusion. For us, it’s not about checking off boxes but about making a true, lasting difference. Having a diverse team unlocks our capacity for innovation, creativity and problem-solving while fostering an inclusive environment that benefits everyone. We strongly encourage applicants from all backgrounds to apply and join us on this important journey.
