About Callsign

Callsign is the app that makes identification quick, secure and private. No more passwords, forms and even business cards. Use your single Callsign across multiple channels and applications, at work and at home.

Job Description

Since our launch in 2012, we’ve been on a mission: to make digital identification simple and secure for everyone, and everything.

In that time, we’ve expanded constantly, and been joined by over 150 incredible people, all with the same vision. We’ve grown in other ways too – we raised $35 in our Series A funding round, and launched our game-changing authentication platform.

Our technology is now being used by hundreds and thousands of users worldwide, including some of the world’s leading financial institutions.

And this is just the beginning.

Over the next year, Callsign will double in size as we continue our mission to make every web, mobile and physical interaction seamless and secure.

We can’t do that alone, though. That’s why we’re looking hire the brightest, most inquisitive minds out there: the people who want to help us change the rules of identity ­– and have the skills and passion to make this mission a reality.
