Mobile Engineer - React Native

Accountabilities:

Develop and maintain a cross-platform peer-to-peer mobile application, taking ownership of features from implementation through testing and release. Ensure the application delivers a reliable, responsive, and secure experience across iOS and Android.

• Build, refine, and maintain features for messaging, voice and video calls, media sharing, device pairing, and identity backup.

• Implement user interfaces and connect them to the peer-to-peer core APIs running directly on the device.

• Integrate native mobile capabilities, including push notifications, camera access, biometric authentication, and background tasks.

• Profile and optimize performance on real devices, focusing on application startup time, extended chat sessions, media processing, battery consumption, and network usage.

• Write and maintain unit and end-to-end tests to ensure application reliability and prevent regressions.

• Support stable releases through continuous integration workflows, crash reporting, and systematic debugging.

• Collaborate with product, design, and peer-to-peer engineering teams to deliver new features and improve the overall user experience.

• Participate in code reviews, promote engineering best practices, and maintain a high standard of code quality.

Requirements:

Candidates should bring substantial experience in React Native development, strong JavaScript expertise, and a solid understanding of mobile application architecture and state management. The ideal candidate is comfortable working independently in a remote environment, optimizing existing applications, and collaborating across technical disciplines.

• Significant professional experience with React Native and mobile application development.

• Strong experience with Redux for state management and Redux-Saga for handling asynchronous workflows.

• High proficiency in JavaScript, including ES6+ features and modern development practices.

• Experience integrating and working with WebSockets and RESTful APIs.

• Familiarity with mobile application performance optimization, debugging, and testing.

• Experience collaborating with distributed or fully remote engineering teams.

• An interest in modernizing, improving, and optimizing mobile or web applications.

• Strong problem-solving skills, attention to detail, and the ability to communicate effectively in English.

• Familiarity with native development languages such as Swift and Kotlin is an advantage.

• Experience with native development and build tools, including Xcode and Android Studio, is a plus.

• Experience building applications with peer-to-peer frameworks or working with decentralized technologies is a bonus.

Benefits:

• Fully remote working arrangement, with worldwide opportunities.

• Opportunity to contribute to innovative peer-to-peer technology and privacy-focused mobile applications.

• Collaboration with an international team of engineers and product specialists.

• Exposure to modern mobile development practices and a distinctive on-device peer-to-peer architecture.

• Opportunity to take ownership of end-to-end features and make a meaningful impact on product development.

• Professional growth through challenging engineering projects involving mobile performance, decentralized communication, and cross-platform development.
