In the interests of copying a useful thread from YC Hackernews. I'm starting up a "Who's Hiring" in the community thread (though there might be scope for making this into a more permanent thing in future like exists for community events: www.opentech.events).
At Security First we are in the middle of putting together a formal job spec (which we will put up here) but just to kick off, we will be looking for another Android Developer to join the team to work on Umbrella. Ideally Dublin based but open to remote for the right candidate. Email jobs AT Secfirst dot org.
