Full-stack Engineer - Operations Engineering Team Hybrid in London We’re looking for a Full-stack Engineer to build the systems that power iwoca’s German business. You’ll join the Operations Engineering team, a cross-functional group that builds the proprietary tools (like our CRM) that our German operations staff use every day. You’ll own high-impact projects from the ground up, using your technical experience and curious mindset to improve how we serve small businesses while also helping to level up the wider engineering team. The company Small businesses move fast. Opportunities often don’t wait, and cash flow pressures can appear overnight. To keep going, and growing, SMEs need finance that’s as flexible and responsive as they are. That's why we built iwoca. 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 The Operations Engineering team is a cross-functional group consisting of three full-stack engineers and one product manager. The team works closely with the Operations, Operations Strategy and Analytics teams to deliver impactful changes across the wider Operations function. The team builds and maintains the internal systems – including tools for underwriting, notifications, and account management – that power iwoca’s German market. They support more than 70 colleagues across sales, credit, and collections who rely on these tools every day. As the German business grows, the Operations Engineering team is moving beyond small improvements and into reworking how work is done. By reducing manual steps and improving how information flows through the company, the team directly influences how quickly other teams can act, how reliably iwoca can support its customers, and where we can most effectively spend human effort. The role You’ll work on the systems that internal teams rely on to serve customers. You’ll take an initial problem, engage with stakeholders, and develop solutions through to delivery and see the outcome in daily use. You’ll design and build full-stack services that support core operational workflows, including customer communication, underwriting, and collections. Simplify workflows: You’ll decide when and what to automate, translating operational needs into reliable code that reduces manual effort. Evolve the architecture: You’ll identify ways to modernise our systems, managing trade-offs to keep them dependable as they scale. Advocate for quality: You’ll be a key part of the team, using code reviews and design sessions to advocate for better engineering practices and staff user experiences. Expand your scope: You’ll join a growing team that supports individual ownership, offering you opportunities to lead projects end-to-end, developing your commercial judgement. The requirements Essential: Proven track record designing and building backend systems using Python, with the ability to work across front-end codebases, particularly React or TypeScript, to deliver projects end to end. You use AI (like Cursor, Claude Code or similar) in your daily flow—whether for work or for fun. You use it to blast through boilerplate and research, so you can focus on the hard parts: complex architecture, rigour, and high-stakes decision-making. Experience working with relational databases, ideally PostgreSQL or similar, with an understanding of performance and maintainability considerations.
