OpenSignal is building the most comprehensive data set on wireless networks in the world. We want to know which mobile networks are the best in any area, where the best wi-fi hotspots are located and how you can get better signal on your cell phone in realtime.

We've had over 2.5million people download our application to date and have worked with the BBC, TIME Magazine, Forbes to publicize our reports on wireless. We've also recently closed our seed round of $1.3million from a fantastic set of investors: O'Reilly AlphaTech Ventures, Passion Capital and Qualcomm Ventures to ramp things up to the next level.

You love the product and have visions for what it could be. It could be cartography, big data, crowdsourcing or wireless networks: whatever it is, there has to be something about this project that grabs you.

Why us?

You'll get a competitive salary (yawn) that depends on experience. In addition, and more importantly, you'll receive equity options giving you a share in the company. As you help us grow the company, you get to reap the rewards. Informal environment & flexible work style. We're based near Old St, London,at the heart of London's tech scene, it's a lot of hard work and a lot of fun.

About you:

You're passionate about building iPad and iPhone apps in Objective C. As long as you can show us evidence of this, your background doesn't matter. You must be able to point proudly to iOS apps that you have built
You're familiar with all areas of iOS design & deployment
You can turn illustrator designs into shiny apps (ideally you can do same goes for back-of-the-envelope squiggles)
The app will be using a SQLite database. To build the app you won't need advanced SQL skills, but if you do have them or if you're a no-SQL pro it'd be awesome

Extra: You have experimented with the black-magic of private APIs. While not our top priority but we are also interested in building an app for jailbroken phones that will dig deep into iOS.
