Full Stack Engineer - New Ventures
Hybrid in London, United Kingdom
We’re looking for a full stack developer to join the Credit Compass team
We’re looking for a frontend-focused Full Stack Engineer to design and build the intuitive, high-performing experiences and services that power Credit Compass, helping small businesses understand, monitor and improve their credit health.
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
The Credit Compass team is responsible for helping small businesses understand, monitor, and improve their credit health by turning complex financial data into clear, actionable insights. The team owns the product end-to-end, from integrating data sources and shaping scoring logic through to designing the dashboards, journeys, and nudges that keep customers coming back. It is a cross-functional team of front-end and back-end engineers, product, design, and analytics, working closely together to run experiments, ship iteratively, and collaborate with other iwoca teams to share data and infrastructure
The role As a full stack engineer in the Credit Compass retention squad, you’ll help turn complex financial data into clear, trustworthy experiences that small business owners want to come back to every month. You’ll work across the stack with a particular focus on our dashboards and journeys, shaping how customers monitor their business health, understand their credit position, and decide what to do next.
Impact on customers
- Build and ship user-facing features on our roadmap – such as Monitoring, Cashflow Analysis and Spend Benchmarking – that make Credit Compass a habit, not a one-off tool.
- Turn raw Open Banking, credit bureau and internal data into clear, accurate visualisations, explanations and nudges that help customers take confident next steps and stay engaged with iwoca.
Ownership and delivery
- Own features end-to-end: from scoping and technical design through to implementation, rollout, and iteration based on what we learn.
- Maintain and improve the core systems behind Credit Compass, ensuring dashboards, scores and data integrations stay fast, reliable and easy to extend as the product and Retention team grow.
- Monitor and debug production issues, quickly identifying and fixing problems to protect user trust and product performance.
Collaboration and experimentation
- Partner closely with Product, Design and Data to shape solutions that balance impact, effort and scalability, using experiments and metrics to guide decisions about customer retention.
- Contribute to squad rituals – from planning and estimation to retros – sharing context, surfacing risks and helping the team adapt as priorities evolve (for example, moving from core retention work into early monetisation experiments).
Craft and tooling
- Write clean, well-tested code in Python/Django and TypeScript/React, and take part in code reviews to keep quality high across the codebase.
- Improve internal tools and CRM integrations that help us respond to user behaviour more quickly and reduce manual work for the wider team.
The salary
We expect to pay from £60,000–£80,000 for this role. But, we’re open-minded, so definitely include your salary goals with your application. We routinely benchmark salaries against market rates, and run quarterly performance and salary reviews.

At iwoca, we prioritise a culture of learning, growth, and support, and invest in the professional development of our team members. We value thought and skill diversity, and encourage you to explore new areas of interest to help us innovate and improve our products and services.

- Offices in London, Leeds, Berlin, and Frankfurt with plenty of drinks and snacks.
- Events and clubs, like bingo, comedy nights, football, etc.
The benefits
- Flexible working hours.
- Medical insurance from Vitality, including discounted gym membership.
- A private GP service (separate from Vitality) for you, your partner, and your dependents.
