Back End Engineer

About the role

We’re looking for a back-end engineer to join the Credit Compass team. You will help design and build the scalable, high-performing 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 [Employer hidden] teams to share data and infrastructure.

As a Back End Engineer in the Credit Compass New Data squad, you’ll help integrate richer data sources (Open Banking, credit reports) into our product. The aim is to deliver increasingly insightful information to small business owners to help them understand their credit position, and decide what to do next. Assist in building, testing, and shipping new user-facing features on our roadmap (such as Monitoring, Cashflow Analysis and Spend Benchmarking). Help ensure the accurate transformation of raw Open Banking, credit bureau, and internal data into clear visualisations and nudges that empower customers to take confident next steps. Contribute to the full development lifecycle—from supporting technical design and implementation through to rollout—for well-defined components and tasks. Learn to maintain and support the core systems behind Credit Compass, focusing on code quality and reliability. Assist in monitoring and troubleshooting production issues, helping to protect user trust and product performance. Partner with Product, Design, and Data to understand customer needs and contribute to solutions that balance technical feasibility with user impact. Actively participate in squad rituals—from planning to retros—by sharing context, asking clarifying questions, and helping the team achieve its goals. Write clean, well-tested code in Python/Django, and actively engage in code reviews to learn best practices and maintain quality across the codebase. Help improve internal tools and CRM integrations that speed up our response to user behaviour and reduce manual work.
