Front-end Software Engineer

About SwanSw s Europe’s embedded banking specialist. We empower software companies to embed banking features like accounts, cards, and payments directly into their products, under their own brand. Swan processes over €1.5 billion in monthly transactions for more than 150 companies such as Pennylane, Indy, Agicap, Libeo and Lucca. Founded in 2019, the company has received growth capital from investors such as Lakestar, Accel, Creandum, Bpifrance and Eight Roads. Swan is a principal member of Mastercard and a licensed financial institution, regulated by the French banking authority (ACPR).MissionBanking belongs in business software. Many software companies already serve small businesses wonderfully – invoicing, payroll, inventory, and more. They’re on a mission to become the central hub for business life. When it comes to financial workflows, there’s still a gap. Critical tasks like managing cash flow, tracking payments or reconciling accounts happen outside the software, in spreadsheets, email threads and banking portals. Business software shouldn’t just record financial activity — it should run it.Job DescriptionSwan is building the future of embedded banking in Europe. We empower companies to seamlessly integrate banking features into their products through our modern GraphQL API, pre‑built front‑end components and comprehensive administration tools. As we scale to serve thousands of businesses and millions of end‑users, we’re looking for talented engineers who want to craft exceptional user experiences that developers and end‑users love.Your MissionAs a Front‑End Software Engineer, you’ll be an autonomous contributor within our focused front‑end team – a center of excellence across our 70+ engineering organization.

internal interfaces, from technical design through production deployment and monitoring.Work autonomously on projects with limited uncertainty, delivering value on time.Reduce scope intelligently when needed to meet deadlines without compromising quality.Handle unexpected complications without derailing timelines – you’re resourceful and pragmatic.Deliver consistently, building trust with your team through reliable execution.Component Library Development & Maintenance (15%)Build and maintain reusable components that are intuitive, flexible and maintainable.Ensure backward compatibility and handle breaking changes gracefully with clear migration paths.Write comprehensive documentation including usage examples, props API, accessibility guidelines and integration guides.Provide developer support by triaging issues, reviewing partner implementations, and improving DX based on feedback.Optimize for bundle size and performance – partners integrate your components into their production apps.Technical Execution & Code Quality (25%)Write production‑grade React, TypeScript and GraphQL code that’s clean, maintainable and well‑tested.Provide insightful code reviews and approve PRs independently, helping elevate the entire team.Write comprehensive tests (unit, integration, visual regression, accessibility) covering edge cases and critical user paths.Design reliable components considering failure modes, edge cases and varied integration contexts.Implement security and performance best practices, ensuring interfaces are fast, accessible and secure.Propose refactoring to reduce technical debt and improve maintainability across both codebases.Collaboration & Communication (10%)Collaborate effectively across teams to solve complex problems spanning front‑end, backend and partner integrations.Explain technical concepts clearly to non‑technical stakeholders.Gather feedback from partners using the component library and translate it into improvements.Provide timely, constructive feedback in code reviews and design discussions.Participate in technical interviews, evaluating candidates and representing our engineering culture.Production Operations & Continuous Improvement (15%)Monitor component usage and performance across partner implementations.Create meaningful dashboards and alerts for the services you own.Participate in on‑call rotation, responding to incidents affecting both our product and partner integrations.Investigate production issues independently, including debugging issues in partner implementations.Handle deployments and rollbacks
