Onfido is the new identity standard for the internet. That means we only need an image of your ID and a selfie to prove that you’re you. In doing so, we help millions of people connect to the services they need and love more easily, speedily and safely than ever before, whether it’s renting a car or opening a bank account. Our vision is to create an open world where identity is the key to access.

We've received over $200 million in funding from world-class tech investors including TPG Growth, Microsoft, Salesforce to back our vision. And we're just getting started.

At Onfido, our AI scientists build the world’s most secure digital onboarding system used by thousands of businesses globally as the next generation of digital identity. We are looking for an exciting and dynamic leader who can lead our amazing team of AI scientists to push the envelope on several unsolved problems like uncertainty modelling, interpretable AI, protection against adversarial and Deep Fake attacks, differential privacy, bias mitigation, and generalised concept drift detectors within human-in-the-loop systems in service to our identity verification and digital identity products. 

As a senior AI leader, you will support Onfido’s hyper-growth and passionately deliver real world value using state-of-the-art machine learning and computer vision techniques.  We build fraud detection systems that operate at unprecedented performance levels with error rates of less than 1 in a million (99.9999% performance levels) while protecting against unknown unknowns?  We detect thousands of fraud attacks daily in over a dozen industry verticals from banking to gaming to the crypto-world to shared economies and others. As businesses and services go online or maintain a purely online presence, secure, fast and reliable digital on-boarding is a necessary and enabling need.
