Finally I've found new job. From the range of offers (four offers from different companies) I've selected one (Mirantis) and as I think the best, in spite of great distance from home (I notched 1 hour and 20 minutes from door to door). US employer, good salary, medical insurance and other benefits makes this company so attractive. Interesting project and opportunity to develop C++ skills along with interest in my AI-research background prepossessed me to sign the offer and contract. I hope it will be great experience for me.
