Front End Developer-UAE

Russian hacker, Vladimir Leonidovitch Levin, attempted the biggest bank heist the world had ever seen via dial-up internet in 1994. Zia Hayat, Callsign CEO and founder, was hooked - armchair fraud became a real possibility. From this moment, Zia knew he wanted to play a part in stopping the bad guys and securing the internet for all. Founded in 2012, Callsign's mission has been to make Digital Identity simple and secure for everyone and everything. In that time, we've grown to over 200 employees, opened offices in Singapore and Abu Dhabi, been recognised as a WEF Global Innovator, and our technology is being used by many of the world's leading financial institutions to keep millions of consumers safe.

But we aren't stopping here. The identity revolution has only just begun, and we are looking to hire the brightest and most inquisitive minds to help us make every web, mobile, and physical interaction seamless and secure. If this sounds like you, let's chat.
