Full Stack Engineer - Credit Compass

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 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.

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.

• 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.

• 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.

• 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.

• 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.

• Significant experience as a software engineer working across the stack, with strong front-end skills in React/TypeScript.
• Experience building and maintaining back-end services in Python, ideally with Django, including designing and consuming API endpoints.
• Confidence working with data-rich products – for example, querying relational databases and integrating third-party APIs.
• Strong communication skills, with the ability to translate business and customer needs into clear, effective technical solutions.
• A product mindset: you care about outcomes over outputs, are comfortable working with experiments and metrics, and enjoy collaborating closely with Product, Design and Data.

• Experience building dashboards, analytics tools, or other products that help users understand and act on data.
• Familiarity with integrating complex external services (e.g. Open Banking, credit bureaus).
• A strong numerical or technical background, with a degree in maths, physics, computer science, engineering, or relevant industry experience.

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.
