Our smart technology, data science and five-star customer service ensures business owners can act with the speed, confidence and control they need, exactly when it's needed. We've already cleared the way for 100,000 businesses with more than £4 billion in funding. Our passionate team is driven to help even more SMEs succeed, through access to better finance and other services that make running a business easier. Our ultimate mission is to support one million SMEs in their defining moments, creating lasting impact for the communities and economies they drive. The team iwoca partners with a variety of third-party platforms, ranging from large banks and comparison sites to small fintechs that serve SME customers. These partners use iwoca’s Lending API to embed iwoca loans into their own customer journey. Partnerships are an important and fast-growing source of customers for iwoca. The Partner Flow team builds new features and optimises existing flows to provide the best possible experience for iwoca's partners and the customers they refer to us.

Adding new functionality to facilitate deeper integrations and ensure iwoca is the best embedded finance provider on the market.

They work in an Agile fashion with two-week sprints and a daily standup.

You’ll be encouraged to bring your own ideas and take responsibility for areas of functionality. Autonomy: Own features and projects from scoping and design through to production. Collaborate with other engineers to meet the team’s goals, whilst being trusted to define your own solutions and work independently on your part of the problem. Design and maintain robust, flexible, and maintainable systems to ensure scalability and fast-paced development. Impact: Deliver new functionality critical to onboarding important new partners. Run experiments (RCTs) and optimise the funnel to measurably improve how partner-referred customers convert. Leave code, docs, and processes in better shape than you found them.
