At Klorie, we’re building a future-proof payment platform for European businesses. We’re looking for a Senior Front-End Engineer who’s equally skilled in building web and mobile interfaces — someone who delivers polished user experiences across platforms.
You’ll lead the development of both our **web application** (React/Next.js) and mobile app (React Native with Expo). From dashboards to onboarding flows, you’ll be responsible for building interfaces that are fast, intuitive, secure, and pixel-perfect.
Core Responsibilities
- Build and maintain the web app using React, Next.js, and TypeScript.
- Build and maintain the mobile app using React Native with the Expo framework.
- Translate Figma designs into responsive, accessible, and performant UIs.
- Collaborate with design and product to refine UX flows across devices.
- Ensure mobile and web apps are consistent, secure, and production-ready.
- Create and maintain shared UI components and design systems.
- Handle app deployment via Expo, including OTA updates, testing, and platform-specific concerns.
Requirements
- 5+ years of front-end experience with a strong focus on React and React Native.
- Proficiency with Next.js and modern TypeScript tooling.
- Experience building Expo-based apps for iOS and Android, with a solid grasp of mobile UX/UI.
- Strong skills in responsive design, accessibility, and performance optimization.
- Familiarity with state management (e.g., Zustand, React Query, Redux).
- Experience working with REST/GraphQL APIs.
- Comfortable shipping and debugging apps across web and mobile platforms.
- Strong collaboration and communication skills in a hybrid work environment.
Nice-to-Haves
- Fintech or SaaS dashboard experience.
- Familiarity with Storybook, design tokens, and scalable component systems.
- Performance auditing experience (Core Web Vitals, Lighthouse, etc.).
- Familiarity with App Store and Play Store processes.
- Experience with mobile-native features via Expo SDK (Push Notifications, SecureStore, etc.).
- Understanding of authentication flows, token storage, and secure UX on mobile.
Why Join Klorie?
- Impact: You’ll own key user interfaces across both web and mobile.
- Autonomy: High trust, high ownership role in a growing product team.
- Flexibility: Hybrid work model (1–2 days/week on-site in Belgium).
