Backend Software Engineer - Contract

London, United Kingdom – Contract

This job description is for a four-month contract position, however, if you’re looking for a permanent role we’d also like to hear from you.

We exist to make credit more equitable for everyone. We believe that context improves credit decisions. When a customer doesn’t meet the criteria of a traditional credit bureau, we offer a second chance, by inviting customers to tell us about themselves.

Aire is building a credit assessment tool that improves human-level intelligence and eliminates its biases.

Aire partners with a range of lenders including Toyota Financial Services, Zopa and N Brown Group to name just a few. We’re backed by venture capital funding.


Our engineering team is growing due to new projects, new product capabilities and new partnerships. Aire is looking to fulfil a 4-month contract position with a senior backend engineer.
