Work with us

Who we are

We are Martin, Andy, Paul and Ed. Error is where we’ve worked since 2010. We design and build websites, web applications and the occasional mobile app, as well as running a hosted software product which we use on every project.

All our work is centred on the human experience, and that’s one of the main reasons our clients love to work with us.

Some of our previous work

Client logos

Our previous clients include Sony Games, the BBC, ITN, Tate, Bupa, the Open Data Institute and many more established businesses and startups. We’re proud to have been honoured at the Webby awards for our design of the National Museums Liverpool web site, and are excited to be working closely with the University of London on a project to map the history of the city over the last 2000 years.

We run a nascent SaaS product called Rooftop CMS, which we use primarily to speed up delivery of sites for our clients, but which we hope will turn into a business of its own.

Our work is strongly design-focused, but we also deliver heavyweight technical solutions too. The two together are what stands us apart from many smaller agencies. Our clients are generally either very commercial (startups, blue-chip organisations who use us to deliver agile solutions), or in the cultural and creative sectors. Both have their challenges and interests, and we like to keep it mixed. Many of our clients have been with us for years.

We open-source as much of our work as possible. Ed and Paul co-maintain a popular Ruby gem, Rooftop CMS is released under the GPL, and our work on Layers of London is all available on Github too.

What’s special about Error

Three of Error

We run Error because we care about the work we produce, and those we do it for. We also care about our colleagues, families and communities, so our working practices reflect that. Generally, we only work 4 days per week, from Tuesday to Friday: Mondays are our own for outside interests or family time. We have a strong remote-working culture, and you can work remotely full-time if you want (Ed and Paul both do). Getting the job done is much more important to us than working hours or formalities.

Error will probably never become a behemoth agency with layers of management and tonnes of bureaucracy. We much prefer to keep things flexible and small-scale, so we can embed ourselves with our clients and focus on fewer things at one time. We are, however, planning to grow a bit: we’d like to get to the point where we can say ‘yes’ to projects more often than we say ‘no’, and have a little more flex in the system.

Are you a good fit for Error?

If you like the sound of working at Error, we’d love to chat to you. How you fit into the team is as important to us as the skills you have; if you think you’d be a good cultural fit for us, you’ll find your niche and add value to the business.

You’ll need to be within an hour or two of UK time, and able to work in the UK - if you’re somewhere in Europe that’s fine, but we don’t think it’s feasible to work across continents at the moment.

If you think working at Error is in your future, send your CV and a covering email to If you’re applying for one of the jobs above please say so. If you think we should be hiring you for another job, pitch your idea.

No agencies please

We know it’s tempting to bombard companies with CVs when you work at a recruitment agency. But honestly, please don’t. If you’re sending us unsolicited stuff and you’re not actually the person applying for the job, it’ll go straight into the spam folder.

Let's create something good.
