About Abound We’re redefining consumer lending in the UK, and beyond. Using advanced AI and Open Banking data, we make fair, affordable personal finance available to more people. While traditional lenders rely almost entirely on credit scores, we look at the full financial picture - how much you spend, and what you can afford to repay to build a deeper, more accurate understanding of each customer's unique financial situation. And we've shown it works at scale. We’ve issued over £1.3bn in loans directly to customers while delivering market-leading credit performance - for every 10 defaults the industry expects, we see only 3. We also reached profitability just 2.5 years after launch. Backed by £2bn+ of funding from top-tier investors including Citi, GSR Ventures, and Deutsche Bank, we’re recognised as one of Europe’s fastest-growing fintechs (Sifted, CNBC). Now, we’re expanding into new markets and product lines - and we’re looking for ambitious people who want to learn fast, take ownership, and grow with us. About the role We’re looking for a Senior Frontend Engineer to help us build high-quality, innovative product experiences that power our fast-scaling mortgage products. This role sits within our mortgage engineering team, where you’ll work across the frontend stack, owning features end to end: from shaping product ideas and UX details through to implementation, launch, and iteration. This role is ideal for someone who thrives in a fast-paced, empowered team; has strong product instincts; is comfortable operating with ambiguity and taking ownership; and takes pride in building interfaces that feel polished, reliable, and thoughtfully designed. What you’ll be doing: Build and ship high-quality product features using React, TypeScript, GraphQL, and Tailwind Lead frontend projects from concept through delivery, including technical design, implementation, testing, and iteration Work closely with product, backend engineering, and business stakeholders to build experiences that simplify complex mortgage journeys and make them feel fast, intuitive, and trustworthy. Who you are Strong professional experience building production web applications with React Advanced hands-on experience coding with TypeScript Experience working with GraphQL APIs A strong understanding of frontend architecture, state management, and performance optimisation Experience with modern testing frameworks, including integration and end-to-end testing A good eye for design, interaction details, responsiveness, accessibility, and overall product polish A product-minded approach: you care about customer outcomes and the “why” behind what you’re building A strong sense of ownership and accountability The ability to uncover unknowns, navigate ambiguity, and turn complex problems into clear, shippable solutions Pride in your craft, clean code, thoughtful reviews, and helping others grow Ideally, you'll also have: Experience in fintech, lending, mortgages, or other regulated industries Experience working with Python or contributing to backend services Experience in early-stage or fast-moving product teams Familiarity with user analytics, feature flagging, and observability tools A data-driven approach to decision-making Openness to change, innovation, and the ways AI will reshape how products are built and used What success looks like You don’t just “take tickets”. You think like a product builder: questioning assumptions, improving flows, and caring deeply about the customer experience. You notice when an interaction feels clunky, when a flow could be simpler, or when users need more clarity. You’re comfortable owning outcomes, making decisions, and pushing work over the finish line in a fast-moving environment.
