DevOps Engineer

About Selina

At Selina Finance, our mission is to provide exceptional value with simple and flexible financial products. We’re achieving this by building a next-generation digital lender targeting homeowners across the UK. More than £2tn of equity value is locked up in UK homes, while homeowners still need to rely on high-interest-rate consumer loans, credit cards, or overdrafts. We believe this is unfair and unnecessary. We offer a financing product unlike anything else out there, one that is as flexible as a current account, as affordable as a mortgage, and as easy to apply for as a consumer loan.

We are building an incredible team and culture of high performance, development, reward and recognition, ready for the next phase of our adventure, and this is where you come in!

We have quite a few things to be proud of:

🌏 We have 19 different nationalities across our London + Manchester offices
