Ling - Senior React Developer

Lead and evolve Ling App’s React Native mobile experience.
$6,000–$8,000/month - Partial overlap with Thailand (GMT+7) hours.

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 $4.5 million in revenue last year, and we're aiming for $8 million in 2026. 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.

In this role, you will:

🚀 Own the development and maintenance of our mobile applications (iOS & Android) using React Native

🏗️ Architect, design, and implement scalable, maintainable mobile solutions

🧩 Design, implement, and maintain backend services and APIs using Node.js

🧠 Take ownership of day-to-day technical and architectural decisions, balancing quality, delivery speed, and product impact

✅ Ensure high standards of code quality, testing, and maintainability through code reviews, unit tests, and best practices

⚡ Identify and resolve performance issues, technical debt, and architectural risks, optimizing for stability and responsiveness

🎨 Collaborate closely with Product, Design, and UI/UX to build solutions grounded in real user needs

👨‍🏫 Mentor developers, conduct code reviews, and actively raise the overall technical bar

🌟 Gradually become the go-to technical authority for the team

📚 Stay up to date with industry trends and emerging technologies to drive continuous improvement and innovation

This is a full-time role, and you’ll need to be available from 14:00–18:00 Thailand time (GMT+7) / 8:00 AM–12:00 PM CET. We also have a preference for candidates who can overlap more closely with our core working hours of 9:30 AM–6:00 PM Thailand time (GMT+7).

This role is not about managing people immediately. It’s about owning systems, decisions, and outcomes, with leadership growing naturally from there.

You will report directly to the Co-Founder & CEO, Simon Bacher, with close collaboration across Product, Design, and QA. 

Over time, you’re expected to grow naturally into a Tech Lead position, based on trust, impact, and results.
