Senior Product Engineer (Full Stack)

Our Mission

At Ophelos we believe in a different way to deal with debt. One that puts empathy and understanding front and centre approaching our customers as individuals no matter what theyre going through.

For too long people in debt have borne the brunt of poor industry practices. Intimidating tactics time-consuming customer service and a one-size-fits-all approach that overlooks the reasons anyone can fall into debt in the first place. Meanwhile businesses suffer too. Poor customer experience translates to poor customer satisfaction high churn rates bad brand reputation and ultimately missed opportunities.

Thats why were taking a radically different approach. Pioneering an industry-first AI-native collections platform we build products that help individuals clear their debts in a way that suits them whilst providing businesses with an improved customer experience and game-changing insights into their customer base.

Since our launch in 2021 weve worked with some of the UKs leading companies including Octopus Scottish Power and Philips helping millions of people move toward a more stable debt-free 2023 we were acquired by Intrum Europes biggest credit management service and have begun the next phase in our growth expansion into 17 European markets over the next two years.
