Senior Frontend Engineer, Source.ag

• 6+ years of experience in React Native with strong proficiency in TypeScript and JavaScript
• Experience building performance-critical features, specifically involving complex lists, maps, or 2D visualizations. You are comfortable stepping outside standard Flexbox layouts to use Skia or imperative animations when necessary
• Deep knowledge of state management patterns (Redux, Zustand, or MobX) with a specific focus on minimizing re-renders in data-heavy applications
• Solid understanding of event-driven architectures, API design, and Offline-First principles (sync engines, local DBs)
• Proven track record integrating back-end services (experience with MongoDB data structures is a strong plus)
• Solid grasp of mobile (iOS) development and release management
• Demonstrated experience in mentoring and influencing technical teams, with the ability to lead technical projects independently
• Knowledge of testing, CI/CD, deployments, and Computer Science concepts (data structures, algorithms, and their performance impact)
• Strong communication skills and a drive to learn and master new technologies
