Job description
Hey there! I’m Simon, the CEO of Ling App. At Ling, we help people learn languages - especially those that aren’t always easy to find in traditional courses. Whether it’s Thai, Serbian, or even Khmer, we make learning fun and accessible through our mobile app.
We’ve grown a lot over the past few years, hitting $3 million in revenue last year, and we’re aiming for $7 million in 2025. To get there, we’re leveling up our team and looking for top talent to help us grow.
Our team is about 45 strong, with half of us in Thailand and the rest spread across the world.
We value high standards, open communication, and a friendly work environment.
If you’re looking for a place where you can make a real impact, work with great people, and build something meaningful, we’d love to have you on board!
We’re looking for a Senior React Native Developer who is ready to step in to fully understand and take ownership of our tech stack and eventually grow into a leadership role on our Development team.. You’ll lead the development, maintenance, and innovation of our app at first and grow into mentoring our developers and helping them grow their skills.
🚀 Lead the development and maintenance of mobile apps for Android and iOS using React Native with Redux
🎨 Architect, design, and implement scalable and maintainable mobile solutions

This is a full-time role, and you’ll need to be available from 14:00 PM to 18:00 PM Thailand time (GMT +7) / 8:00 AM to 12:00 PM CET.
The ideal candidate is easy to work with, willing to take on challenges, and not afraid to openly communicate across departments. You should be able to break down complex technical topics so others can understand them.
We’re looking for someone who is supportive, open to feedback, and committed to our mission of helping people learn languages.
If you’re entrepreneurial and like to take initiative, you’ll fit right in!
To excel in this role, you need:
