The human element
We're a tech firm at heart, firmly focused on research and engineering. But even the most advanced technology has people at its core.
And our ever-expanding team of engineers and developers are just that – real people with a real passion for innovation and teamwork, focused on a common goal.
Digital trust is broken; we’re helping to fix it.
Innovation is a double-edged sword. As new technologies emerge, the bad actors – the fraudsters and scammers – are quick to adopt and adapt these technologies to their own criminal intentions.
Callsign’s technical experts are leading the fight against fraud. We're building a better, safer digital future for everyone by developing technologies that help global business establish digital trust with their users and put identity at the heart of every digital interaction.
Callsign is flexible, versatile, and vastly powerful. Our codebase allows our customers to operate our product in whichever way works for them – cloud-enabled, on-premises, or even in a hybrid mode.
But it's more
than just code
Whatever technical abilities you bring to the table, we’ll value your people skills just as much.
Whichever team or location you work in, you’ll find Callsign to be a welcoming, respectful and above all, engaging environment. From skills and career building opportunities to social events, we aim to encourage, nurture and develop every one of our people.
Be part of a global team, working together to develop game-changing products on the global stage.
From lunch-and-learn sessions to training, we’ll give you the tools and skills to get where you want to be.
Data led and evidence driven, our autonomous tech-first ethos is present in every element of our day-to-day work.
