• Optimize performance and scalability to support a growing user base.
• Work closely with designers and product managers to turn ideas into reality.
• Maintain high engineering standards, including writing clean, maintainable code and automated tests.
• Collaborate with the backend team (NestJS) to integrate APIs and improve overall system efficiency.
• Participate in code reviews, architectural discussions, and mentoring junior developers.
• Help shape our mobile tech strategy as we scale.

What We’re Looking For

• 4+ years of experience with React Native and deep knowledge of the mobile development lifecycle.
• Strong proficiency in TypeScript and modern JavaScript (ES6+).
• Experience working with React Navigation, Redux, and Expo.
• Familiarity with native modules (Swift/Kotlin) and bridging when necessary.
• Comfortable working with REST APIs.
• Knowledge of mobile performance optimizations and debugging tools.
• Bonus: Experience with NestJS, PostgreSQL, AWS, or Firebase.
• Startup mindset: you thrive in a fast-paced environment, love shipping quickly, and take ownership of your work.

Why Join Us?

• Fast-moving, high-impact work—your code will be in users' hands quickly.
• Ownership & growth—we believe in empowering our engineers to solve real problems.
• Competitive salary—we reward great work.
