About This Role

Headquarters: Germany
URL: https://ridr.bike/

We are a founder-driven company focused on building impactful, community-driven solutions. We believe great work comes from people who are enabled to grow – that’s why we focus on skills, mindset, and real ability rather than formal degrees. Our goal is to create an environment where talent can thrive every day. Through a hybrid way of working, we give our team the flexibility to focus on what truly matters – meaningful work, personal growth, and sustainable performance. We exist to create opportunities for people who seek purpose in what they do, enjoy being challenged, and want to build work around the life they aspire to live.

The Role

Working hand-in-hand with our Team Lead, you will take deep technical ownership of the RIDR app. This means bridging design and engineering to transform Figma prototypes into polished mobile experiences, while simultaneously architecting the Convex backend systems that power our gamified community. You will build product features—from highly performant, cross-platform UI to robust backend systems and social interactions.

What You’ll Do

Implement screens and components from Figma designs into Expo / React Native, ensuring flawless operation across iOS and Android.
Design and implement backend systems in Convex for gamification (challenges, levels, XP), social features (posts, likes, feeds), and spaces.
Build adaptive layouts and implement system-integrated dark/light theme switching.
Architect data models, real-time sync, and privacy-preserving aggregation for GPS heatmap data.
Manage basic GitHub CI/CD and Expo EAS deployment workflows.

What You Bring

Strong proficiency in React Native, Expo, and TypeScript.
Strong backend development skills with Convex (or deep experience with Firebase/Supabase and willingness to adapt).
Experience building gamification systems or social platform features.
Database design expertise for real-time, social applications.
Methodical testing mindset: you verify on physical devices, and design systems for data integrity, performance, and user privacy.
Understanding of React Native styling, flexbox, and platform-specific nuances.

Nice to Have

Experience with UI component systems (shadCN UI, HeroUI) or animation libraries (React Native Reanimated).
Understanding of mobile app backend constraints (offline-first, sync strategies).
Knowledge of social feed algorithms, content moderation systems, or analytics pipelines.
Familiarity with location-based service architectures.
