Back End Engineer - Partner Tech Team

Hybrid in London / Remote within the UK

The company

Imagine a world where every small business has the power to thrive. That's the world we're building at iwoca. Small businesses aren't just statistics – they're the heartbeat of our communities, the character of our high streets, and the engine of our economy. Since 2012, we've revolutionised how these businesses access finance, turning what was once a lengthy, frustrating process into something remarkable: funding that's fast, flexible, and actually works for modern businesses.

Our impact speaks for itself: we've provided billions in funding to more than 150,000 businesses across Europe, making us one of the continent's leading fintech innovators. But we're just getting started. Our mission? To empower one million businesses with the financial tools they deserve.

We combine cutting-edge technology and data science with genuine human understanding to make finance feel less like a barrier and more like a superpower. Whether a business is managing cash flow or seizing unexpected opportunities, we ensure they get the funds they need – often within minutes.

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 Tech 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. The team’s responsibilities include:

• Continually improving our Lending API and other developer tools, so that partners can integrate with iwoca quickly and easily.

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

• Improving the conversion rate of customers who come to us through partners, by streamlining the journey and removing obstacles.

The team is made up of two engineers plus a product manager, working closely with an internal team of commercial stakeholders. Partner Tech is remote/hybrid-friendly, meeting up for team days in the office once or twice a month, but not on a fixed schedule. They work in an Agile fashion with two-week sprints and a daily standup.
