About The Position

Qompyl is redefining trading by focusing on a hands-on, visual, and gamified strategy builder that empowers traders to create and refine their strategies with ease. Our core service is a mobile-first platform, emphasizing simplicity, accessibility, and real-time interaction. We are building an interactive fintech product where performance, clean UX, and seamless integration between front-end and back-end systems are critical. We are seeking a Full-Stack Developer with a strong front-end orientation, particularly in React Native, to help build and scale Qompyl’s mobile-first trading platform. While this is a full-stack role, the primary focus will be on mobile front-end development, user experience, and real-time data interaction. The ideal candidate is comfortable contributing to back-end systems (Python/FastAPI) but thrives in building intuitive, high-performance mobile interfaces. This role is ideal for a front-end-leaning full-stack developer who enjoys building mobile experiences and can confidently collaborate on back-end systems.
