Our neighborhood

These are our surroundings, what we see every day on our way to work.

Public transport

Metro line A and tram 11 around the corner. Tram 10 and 16 around another.

Team space

We don’t put more than 6 people in a room. No open space. No solitude. Ideal compromise for cooperation.


Need 3 screens and 3 tablets? Here you go.

More equipment

…or 2 large screens and no tablet…

Farmers’ market

Just around the corner you can get bio goods at Prague’s most popular farmers’ market.

Parks all around

We have 3 parks in the immediate neighborhood.

Pro tap in the kitchen

Draught Kofola on the house + another beverage by people’s choice.

Backyard garden

This is what we see from our windows…

Who we are

We're a Prague, Czech Republic-based, small gang of programmers who have been together for countless years. Many of us still remember good old 8bit times, the Amiga, Atari ST, the first PCs/Macs and the time before the Internet came around. We've programmed for mobile devices since it became possible - we went through the time of mobile Java starting with Nokia 6230i, the boom of color phones and the wild platform fragmentation that it caused (making 150 different ports of an app a neccessity) all the way to today's open operating systems on smartphones and tablets (and soon smart TVs). Fragmentation, however, is here to stay. It only changes its form and shape. Earlier we had to live with different Java implementations, now it's different operating systems plus HTML5. But we love new technologies and we're eager to play with new ones. That's what 4mobile's all about. If it's battery-powered, we can program it.

We develop both to order and our own projects.

This all doesn't mean we're scared of back-ends, SQL, web services, the cloud or anything a modern application has to do - in fact, that's where we're rooted, mobility hasn't been around all the time, after all, and we did it all. So we can deliver the entire package. Including solutions in the cloud, media streaming, around the clock monitoring and support of critical systems, you name it.

Talent-wise, we have older and younger (our current age span is 20-50 years with a mean just below 30), game and business-savvy individuals among us. Just what a top-notch, no-nonsense programmer pack should be.

And we'd like to make you part of that team.


Part-timers and mature candidates

All that matters is getting the job done

Our philosophy is that a great team needs great people of all ages. For some reason, some companies won't hire people above 45. We don't understand this as we're happy to welcome aboard anyone irrespective of their width, height, weight, age, color, sex or anything else that has nothing to do with their perfomance - as that is the one thing that counts.


Candidates before job descriptions

If you're good we're interested

Our primary interest is to work with great people. We often change titles/positions around when we meet someone awesome, so don't fret if you consider yourself more or less experienced than one of our open positions.

In the end, the open positions list is what we need at the moment - many people end up finding out their skill set is more useful elsewhere within the company anyway, so please don't take these literally.

Like JavaScript? It's all the rage now - not just on desktops but also on all smartphones.
