We are creating an iOS/Android app that will make it easier for people to find time to do things with friends and colleagues (& wider). See http://whosup.buzz We have developed a sophisticated approach to ranking and distributing event ideas. We are only looking for the strongest scala-spark developers with experience using ML Lib. This person will take over from a talented Cambridge Undergraduate and take the implementation to the next level (lot's to do & refine). There will be a interview test on you Scala Spark skills.
