Application Software Engineer

London, United Kingdom – Full-time

At Aire, we believe that when it comes to credit, many of us are missing out.

For lenders, access to only historical data has limited their ability to make the credit decisions needed in our modern economy. This impacts everyone, delivering less value for lenders and making access to credit for some, impossible.

But at Aire, we’re using state-of-the-art machine learning techniques to engage directly with consumers to deliver the fuller picture to lenders. We call this first-party data and we believe it’s shifting the balance of credit scoring for everyone, forever. Because, when you see a customer in three dimensions, credit decisions become clear.
