About the role

We are looking for a bright, enthusiastic, and highly organised iOS Developer at SamKnows, (offices in London Bridge, Central London).

We are an independent, profitable, and well-funded company that is continuing to scale fast.

SamKnows is currently seeking a Mobile Application Developer to work on our suite of iOS applications for measuring network performance. These applications make extensive use of network connectivity and a variety of other Apple technologies. We currently have over 250,000 users of our mobile apps worldwide.

You should have some experience working in iOS development, modern user storyboarding in iOS, app localisation, and the Apple store distribution infrastructure.
