Callsign

At Callsign we are changing identity. We are an identity fraud, authorisation & authentication company, solving the challenges that organisations face in getting their users on to & interacting with their digital platforms.

We use deep learning techniques to combine device, location and behaviour datapoints with dynamic policy management and multi-factor authentication, to verify that the user is who they say they are.

Our aim is to make identification more secure and simple – helping everyone to get on with their digital lives in the most seamless and secure way possible. If you’re interested in working for a company that’s changing the face of digital security globally, then you’re in the right place. We’re a talented team of research scientists, engineers and developers working with the latest technology to help make the digital world a more secure place.

Our Culture

Callsign is a talented team of people who are passionate about their craft and who care about making the digital world more secure. We work collaboratively, adopting agile principles and methodology and use the latest technologies to develop a reactive and scalable platform.

With boardgames nights, pop-up social activities and company parties, it’s easy to meet new colleagues and feel part of the team and, with breakout spaces throughout the office it’s easy to find space to socialise. But we also know how important it is to have time away from regular meetings, so we’ve allotted core development time at the end of the week.

Our Values

Challenge 
From challenging the status quo and driving an identity revolution, to building a world that protects user identities, we always set the bar high.

Mastery 
To deliver what we say we will, we’ve got to be the best at what we do, while
making sure there’s an artistry to our expertise.

Championing 
We’re determined to defend our customers against the bad guys, making identification safe and easy for everyone.

Integrity

This is the reason we do what we do to protect identities without ever betraying trust.

Community

Building a community at work, a community of partners and customers, and supporting the wider community outside of Callsign, really, really matters to us.
