OpenSignal - London, UK (Full time, permanent) At OpenSignal we're using mobile apps to tap into the smart phones we're all carrying around with us to build up global crowdsourced sensor networks. Our first sensor network is for wireless signal [1] where we are building a global database on the coverage and performance of wireless networks (both mobile + WiFi) on a scale that has never before been possible. Our second sensor network is WeatherSignal [2], which uses the barometers, thermometers and hygrometers on smart phones to crowdsource weather data and we have already published a scientific paper [3] showing the potential of this approach. Our third sensor network is WifiMapper [4] which leverages sensors and the community to build the best free Wifi database in the world.

If the concept of crowdsourced sensor networks appeals to you too then please get in touch. We are hiring for all manner of different roles right now (Android, Full-stack, Backend (Python), Frontend, UX/UI & Data Science(R, Pandas, Numpy, Spark)) but most of all we are just looking for smart, like minded people rather than people with specific, existing skills. We raised our $4 million series A [5] from Qualcomm Ventures, O'Reilly Alphatech Ventures & Passion Capital and we are growing fast.
