Responsibilities:

• Develop and maintain responsive, high-performance web and mobile applications using React and React Native
• Write clean, maintainable, and efficient code following best practices and established coding standards
• Collaborate closely with product owners, designers, and other developers to define, design, and ship new features
• Participate in code reviews, offering and receiving constructive feedback to ensure code quality and consistency
• Implement unit and integration tests to ensure the reliability, scalability, and robustness of the application
• Debug, troubleshoot, and resolve performance issues across platforms

Requirements:

• Bachelor’s degree in Computer Science, Software Engineering, or related field
• Strong proficiency in React and React Native development
• Experience working with RESTful APIs, third-party libraries, and cloud-based integrations
• Solid understanding of modern front-end development tools (e.g., Redux, TypeScript, Webpack, ES6+)
• Strong problem-solving skills and attention to detail
• Excellent communication and teamwork skills
• English level: Upper-Intermediate or higher

In return, we offer:

• The friendliest community of like-minded IT people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program is designed to meet our team’s needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort, and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups

Come on board, and let’s grow together
