The ideal candidate will have experience in building beautiful user experiences and robust functionality. With a few years of development under your belt, you’ll have a mastery of modern CSS and JavaScript and a solid understanding of PHP and common CMSes and frameworks.

You’ll bring a passion for building things that people love to use, a can-do attitude and an inquiring mind. In return we’ll help you to grow, giving you an unbeatable variety of interesting projects for big name clients, room to learn new tools and technologies, and a friendly, supportive atmosphere to work in.

Apply for this role if you:

Who we are

Four is an award-winning creative agency working for clients of all shapes and sizes in the UK and internationally.  

Our Creative Technology unit, of which this role is part, combines Four’s existing digital business and two strategic acquisitions in 2021 and 2022 – Joi Polloi and Marmelo. In practice this means you get the security and support of a larger agency with the focus and friendliness of a small start-up.

We work with a huge range of clients, and every project is different. We’ve got a particularly impressive track record in the cultural sector (especially museums and heritage), broadcast and media, brands and retail, health, property, tourism and the public sector.  Recently we’ve delivered sites, apps and interactive experiences for the Science Museum, BBC, Amazon, Channel 4, London’s West End, the Royal Shakespeare Company and the University of Sheffield.

We wear our ‘creative technologist’ badges with pride, helping our clients find the right mix of technologies and channels to tell their stories and achieve their goals.  We engage people, transform organisations and elevate brands through unified digital experiences, bespoke platforms and innovative products.

Everyone has the freedom to flourish in their roles whilst allowing you to not just suggest, but to create change and better ways of thinking and doing things.

The day-to-day

Four operates a flexible working policy – you can work from home or wherever you like, unless you have face-to-face commitments such as client meetings and events, team meetings or training. 

For this role we are interested in candidates whose home office would be in the Sheffield in the UK: though we have other offices in London, Cardiff or Aberystwyth.

We invest in making sure our offices are beautiful spaces in interesting locations, where we can collaborate to produce multi-award winning, innovative work.  Regular team drinks and lunches are well-attended, and tea, coffee, fruit and cereal are provided.
