Submit your CV and get offers from companies, startups and science labs according to your skills and then get interviewed.
After passing the interview, you will receive a job offer. When there are intentions to sign a contract on both sides, you are waiting for the move. We don't care where you live now. The main thing is your desire to move.
Regardless of the format of future work, you will have to move from the territory of Russia or Belarus to free countries. For this, there is a relocation service, which will be available after a successful interview with the employer.
